Mathematical methods always serve as powerful tools for minimising total inventory costs. In this paper, we have considered a retailer's inventory problem in order to determine an optimal strategy that minimises the total inventory cost under various constraints. Here, the constraints include constant deterioration, power-pattern demand, permissible shortages, partial backlog, different inventory costs, and inherent imprecision of various expenses concerning the current scenario. Subsequently, we develop the mathematical model of the problem together with its solving policy in a crisp as well as fuzzy environments. Moreover, we provide several numerical illustrations to validate our findings. Finally, we present several managerial insights for inventory managers based on the sensitivity analysis of associated parameters. Journal: Int.

A review of the extant literature identified an opportunity to build user-friendly human-robot interfaces and confirmed the need to enhance the perceptions of human safety conditions and requirements during interactions with cobots when performing manufacturing tasks. Therefore, this study seeks to deepen the knowledge regarding the use of cobots, based on introducing novel safety system architecture for human-robot collaboration in a shared workspace. The degree of collaboration is investigated, focusing on the safety requirements when human operators perform tasks involving cooperation between humans and cobots in a combined workstation. As a result, this study extends the previous literature by proposing a conceptual safety system architecture that is especially useful for covering safety requirements during the design stage of a collaborative workstation so as to minimise safety risks to humans, resulting in a dynamic safety framework that allows for the use of advanced robotics in an Industry 4.0 environment.

However, most researches in this area have only considered the cost and profit functions. In this research, the optimisation of multi-product CLSC considering customer satisfaction with dimensions such as quality, service level, lead time, and environmental pollution along with the profit function in different periods is considered. The uncertainty of demand in the form of grey numbers is considered. To optimise this NP-hard problem, a multi-objective meta-heuristic pareto-based enhanced firefly algorithm was used. The purpose of the proposed model is to determine the optimal production quantities of each product and finding the location of the warehouse at each stage and period in the CLSC. Finally, for the validity and analysis of the model, a numerical example has been considered. Journal: Int.

The main objective of this study is to provide a method for increasing power quality with hybrid access points to RES using optimal FOPID controller settings and UPQC. Non-linear system load and failure conditions seem to be the root of PQ issues with HRES. The UPQC uses series and shunt filtering methods to resolve the PQ issues with the aid of hybrid Honey Badger-salp swarm optimiser (HBD-SWO) method that inherits the qualities of SSA and HBA methods. The new technique involves fine-tuning the FOPID controllers' variables of the shunt and series devices of UPQC. The efficiency of the proposed method is compared with that of conventional methods to prove the efficacy of the proposed approach in PQ enhancement. Journal: Int.

A coconut oil industry with five production processes: expeller-pressing, refinery, extraction, hydrogenation, and pelletising can produce up to 11 products. A product mix problem often arises in the determination of the quantity of each product to be produced. As such, product mix decisions can significantly affect profit generation. This research aims to develop a mathematical model based on linear programming (LP) to maximise profits. The optimisation model developed in this study estimates that the industry can increase profits by 43.9% by applying the best product mix decision. A sensitivity analysis shows that changes in capacity affect the model. Three production flow scenarios were tested in the LP model. Scenario 1 (adding refinery 2, using it like refinery 1 plus using refinery 2 to produce refined bleached deodorised hydrogenised coconut oil super) can increase the industry's profit by 28%.

The process capability indices <i>C<SUB align="right"><SMALL>p</SMALL></SUB></i> and <i>C<SUB align="right"><SMALL>pk</SMALL></SUB></i> are based on the assumptions of independence and normality of the process characteristic. Many authors have reported that ignoring the autocorrelation present in the process characteristics leads to wrong decisions. In this paper, the effect of the autocorrelation on the capability indices <i>C<SUB align="right"><SMALL>p</SMALL></SUB></i> and <i>C<SUB align="right"><SMALL>pk</SMALL></SUB></i> is discussed. The second order autoregressive process AR (2) is considered to model the data from an autocorrelated process. To reduce the effect of autocorrelation on the indices and the skip and mixed sampling techniques are implemented to form rational subgroups in the design of these indices. Results based on simulation study confirm that both the techniques improve estimates of capability indices <i>C<SUB align="right"><SMALL>p</SMALL></SUB></i> and <i>C<SUB align="right"><SMALL>pk</SMALL></SUB></i> significantly.

A repository of artefacts is developed through system initiation, analysis, design, and implementation. Data about the problem is gathered, and existing procedures are analysed and improved using key stakeholders' knowledge to maintain continuous communication throughout the stages with involved parties. The DSS adopts mathematical programming and a heuristic to obtain exact and good solutions. The nearest neighbourhood heuristic is employed to solve large instances. IDEF0 and a problem statement are employed for system initiation. A cause-effect analysis is conducted for problem analysis. Use-case diagrams and narratives are used for requirements analysis. Logical and physical data flow diagrams are developed for system design. The system is implemented using Excel internal VBA language and the Application Programming Interfaces for Frontline Solver and Google Maps. Fico Xpress is used for exact solutions. Journal: Int.

In order to ensure the safe and orderly operation of air traffic flow, it is urgent to propose efficient conflict-free trajectory generation methods. The development of artificial intelligence technology provides a new way for the design of conflict-free trajectory generation algorithms. As a consequence, machine learning can be applied to conflict-free trajectory generation. Intelligent agents learn autonomously in their interactions with the environment, thus possessing the ability to make autonomous decisions. Simulation experiments in different scenarios have shown that the algorithm proposed is effective. Journal: Int.

Electric and hydrogen vehicles have emerged as sustainable alternatives, reducing greenhouse gas emissions and improving air quality. Both offer co-benefits in reducing air pollutants from common emission sources. However, the study shows that despite higher demand for electric cars, hydrogen car manufacturers still yield greater profits. The preference for consumers and governments is more towards electric cars due to higher demand and better environmental impact. Nevertheless, the hydrogen car market remains profitable for manufacturers. Governments may play a role through tax and subsidy policies to incentivise consumers towards more sustainable choices, contributing to environmental protection and public health preservation.

Title: Performance and reliability analysis of pulping system in a paper plant Abstract: This paper presents the performance and reliability analysis of the pulping system in a repairable paper plant utilising the fuzzy λ-τ method based on trapezoidal fuzzy numbers. The configuration of the pulping system has been modelled by the Petri net model. To deal with imprecision and vagueness in failure/repair data, trapezoidal fuzzy numbers are used to fuzzify the failure and repair data of each component of the pulping system. The fuzzy λ-τ method has been utilised to evaluate reliability factors of the pulping system including availability, reliability, failure rate, repair time, mean time between failures and expected number of failures at different spreads. The analysis is beneficial for plant managers to enhance the performance of the pulping system by developing and implementing appropriate maintenance strategies and policies. Journal: Int.

The estimation of input coupling terms does not depend on historical data. The complex interconnected systems with input couplings are decomposed into individual subsystems. The proposed strategy not only alleviates computational load, but also optimises the interaction between subsystems, effectively addressing the output oscillations of the system during abrupt reactions of input couplings. The convergence of the control algorithm and the stability of the closed-loop system response are examined, and the efficacy of the proposed control method is validated by comparative simulations.

For this reason, various studies have relied on discrete event simulation tools to create and evaluate the flexible manufacturing system's performance using multi-objective optimisation methods. However, the literature lacks comparative studies of these different methods in the flexible manufacturing systems optimisation context. This paper aims to compare the two optimisation methods, PROMETHEE and OptQuest, based on multi-objective efficiency. PROMETHEE is based on ranking simulation results, while OptQuest is an iterative method using a meta-heuristic. This comparison showed that OptQuest is the best-performing method. Journal: Int.

Accordingly, the sewage treatment industry has to push energy and industrial structure transformation and upgrading. Whether the inlet pump room can perform effectively, and energy-savingly, will directly impact the economic operation of the whole enterprise. This paper seeks to build a complete energy efficiency assessment model for the pump room. Firstly, the calculation and standard range of five relevant indicators are carried out. Secondly, the indicator weight algorithm of BP-DEMATEL and improved CRITIC technique is proposed, and the linear coupling weighting is adopted according to minimal discernment information. Alternatively, an OPTICS clustering approach based on Bayes optimisation is also presented to obtain the range for four operating conditions. Finally, empirical research is carried out on the case of the pump room in Shanghai. The researched model may greatly increase the assessment performance, giving the scientific reference value for the optimisation of the pump room renovation. Journal: Int.

Additionally, there can be multiple workers at individual manufacturing workstations. The MPMW-WSP focuses on the safe exposure of workers to a given ergonomic hazard that is dominantly present in the workplace. Dominant ergonomic hazard can be either a single-limit hazard or variable-limit hazard. A hybrid solution procedure is employed to solve the problem. It consists of a heuristic method to estimate an initial workforce size and an integer linear programming (ILP) model to determine a minimum number of workers to be rotated among different tasks so that their daily hazard exposures are within the permissible or recommended limit. Numerical examples and computation experiment are also presented. Journal: Int.

A conceptual model was developed based on an extensive literature review. The study was performed in a mixed mode based on the case study and survey. In the case study, ten public and private banks participated. The survey was conducted with responses from 54 banks using a semi-structured questionnaire. The conceptual model was validated, and the relationships within the model were tested using structural equation modelling (SEM). Additionally, the impact of CPS implementation on cost reduction, improved Performance, and enhanced resource utilisation was assessed. The data collected was analysed using SmartPLS 4. The findings indicated a positive influence of Interconnectivity and ISV on CPS implementation, leading to increased performance and resource utilisation. However, it is worth noting that the study did not find a positive effect of CPS implementation on overall cost. Journal: Int.

Real-time experimental data on specific enthalpy of steam has been collected and used for training of proposed models. The machine learning models have been trained using different training algorithms namely Levenberg-Marquardt (LM), Bayesian-regularisation (BR), scaled-conjugate gradient (SCG), one step secant (OSS) and resilient back-propagation (RB). The prediction performance of these algorithms has been analysed in terms of root mean square error (RMSE), mean absolute error (MAE), mean absolute percentage error (MAPE) and bivariate correlation coefficient (COR) for a maximum step size of 30 multistep predictions. The results highlight superior performance of NARXNET model designed using BR-algorithm compared to prediction models designed using other training algorithms. Journal: Int.

In order to better monitor the faults of bearings, this article combines the concept of deep learning and designs a bearing fault diagnosis and monitoring software system based on lightweight neural networks to resist coloured noise. This system is developed based on MATLAB App Designer. When testing the system, five different bearing datasets, namely MFPT, Paderborn, IMS, Ottawa, and CWRU, are applied. Considering that the data in actual scenarios contains complex noise, coloured noise signals are added. Compared to traditional fault diagnosis software that requires pre writing data into the program, this software can perform real-time processing on any single column vibration data file. By using lightweight neural network methods to preprocess the data collected by sensors, the SqueezeNet network has a faster speed to extract significant features of vibration. This software system can achieve time-frequency domain image output of signals, with multiple noise reduction methods. It can also calculate the frequency of faults based on bearing model data. Through envelope spectrum images, the location of faults can be monitored and email reminders can be sent to engineers. Journal: Int.

There are seven non-identical components in the system, which are arranged into three structures. The two structures operate in parallel and each having three components connected in series; while the third structure has a single component connected with the extreme components of the parallel structures. The expression for reliability of the system is assessed using the path tracing method. The failure rate of the components is assumed as constant triangular fuzzy number and thus they follow the exponential distribution. The α-cut method is used to defuzzify these fuzzy numbers for determining reliability measures. The intervals for fuzzy reliability and MTSF of the system have been computed for both non-identical and identical components. An illustration of RLC system has been described to highlight the application part of the research work. Journal: Int.

These disorders include infections, tumours, trauma, degeneration, structural defects, stroke, and autoimmune disorders. The devastating consequences of brain disorders on the lives of humans could be reduced by early diagnosis. The diagnosis of brain disorders consumes higher time and effort by physicians compared to computerised diagnosis techniques. Several computerised diagnosis algorithms have been developed to improve and optimise the diagnostic capabilities of physicians. Magnetic resonance imaging (MRI) is an effective tool used for brain disorders diagnosis. MRI detection of multiple sclerosis (MS) is extremely complicated due to several reasons, including the anatomical variability between patients, lesion location, and the variability in lesion's shape. This paper reviews several computerised algorithms used in diagnosing brain disorders, to present the most efficient techniques that reduce the physicians' diagnosis time and effort of MRI images, hence, starting MS treatment at earlier stages.

E-warehouses are operationally different from traditional warehouses. To accelerate fulfilment speed, an e-warehouse splits multi-line orders across multiple picklists. A key research question is how to manage the flow of picked items so that the number of shipped parcels is minimised. This research introduces the e-warehouse order consolidation (WOC) problem. Tote consolidation is a key link between order picking and parcel packing. We identify key modelling elements and formulate the associated constraints and objectives. The WOC mixed integer program is tested on a series of problems, and we illustrate the operational and business value of controlling the tote consolidation process. Order similarity between totes is used to develop two fast heuristics. Two controllable design parameters are investigated, the number of packing stations and the number of totes assigned simultaneously, on parcel packing efficiency. Journal: Int. J. of Industrial and Systems Engineering Pages: 421-441 Issue: 4 Volume: 49 Year: 2025 Keywords: fulfilment speed; shipping costs; parcel packing.

The approach of the study is empirical where dataset from different systems is used to develop ML and DL models to forecast more accurately transportation time and improve profitability. Various models, e.g., linear regression, deep learning, and distributed long short-term memory (DLSTM) networks are used. It is found that the DLSTM regression model shows superior performance in forecasting the delivery times compared to the other models, achieving an accuracy of around 90%, as the model has the ability to handle complex and nonlinear relationships among variables. The findings underscore the potential of machine learning (ML) and deep learning (DL) in improving predictability and profitability aimed increasing digitalisation in global transportation.

The novelty of the anticipated control strategy lies in the use of FOID control action, which generates the counteractive action to improve the control performance. The controller's gains are optimised by an optimisation algorithm called spider-monkey optimisation (SMO). The objective function is considered as the sum of the integral of the squared deviation of the microgrid frequency (ISFD). The proposed controller's response is then compared with the integer-order counterparts to investigate the effectiveness of the suggested controller. The detailed simulation results demonstrate the robust behaviour of the proposed control scheme and establish its superiority over other investigated control structures. Journal: Int.

This study aims to improve the quality of manufacturing processes from material acquisition to the end of production using multi-agent technology (MAT). The literature review identified five factors and their 31 governing variables, and their impact is analysed through AHP, DEMATEL, and TOPSIS. AHP was used to study and establish priority orders. DEMATEL was used to develop inter-relationship and TOPSIS to validate the global ranking evolved through AHP. 'Manufacturing process' along with 'quality aspects' have evolved most significant factors for controlling quality. Their significance is increased since they were discovered to be the most influential in affecting other factors. The detailed research and discussions in this article may allow industrial organisations to raise quality standards, hence increasing customer support, lowering costs, and improving efficiency.

We find that when the problem of difficult financing for enterprises exists, the approved loan amount positively affects the level of energy conservation and emission reduction through production volume. The level of energy conservation and emission reduction is not related to the loan interest rate. The fixed cost investment in energy conservation and emission reduction is a major factor for enterprises to take energy conservation and emission reduction measures. Even with financing difficulties, because of the existence of carbon taxes and subsidies, companies tend to adopt energy-saving and emission reduction measures. The heterogeneity of enterprise scale only exists when financing difficulties exist. Once financing difficulties are resolved, there is no heterogeneity in the impact of enterprise scale on energy conservation and emission reduction levels. This means that the energy conservation and emission reduction levels of enterprises of different scales are ultimately the same. Journal: Int.

To address these challenges, this study aims analysing the impact of multi-agent technology (MAT) on the quality standards of high-tech manufacturing (HTM). The extensive literature was used to explore 8 factors of HTM and 45 variables of MAT. A hybrid multi-criteria decision-making technique was used to analyse the factors and variables. The HTM process is a highly prioritised and impactful factor. <i>Process monitoring, automatic customised test plans, adaptive agents, demand forecasting agents, and virtual manufacturing</i> are the top five globally ranked variables. The findings of this article provide ranking order and determine the relationship between factors and variables for the integration of MAT in HTM. This bridging can assist designers in improving the design quality, manufacturers in increasing process quality standards of products, and market experts in selecting the potential market.

This review uses a systematic literature network analysis to provide an overview of the SCRM research landscape, with emphasis on optimisation approaches, mathematical modelling tools, and the identification of seminal studies and relevant keywords used in SCRM research. However, there are few quantitative models that represent the relationship between supply chain surplus, sustainability, and resilience in SCRM literature. The study has limitations since it only sources from a single database, and more clarity is needed on the effectiveness of optimisation in SCRM, which can be further evaluated through case studies and empirical studies.

However, to date, their adoption in the healthcare sector is still very limited. Few studies applied a systematic literature review (SLR) for blockchain adoption in healthcare. In this research study, the first contribution is to identify the factors that influence the adoption of blockchain by applying the SLR approach, understand how these factors are interrelated, and discuss the main challenges of blockchain adoption. The findings demonstrated that, the unified theory of acceptance and use of technology (UTAUT), the technology acceptance model (TAM) and its extension were the most popular models used for blockchain adoption. Then, we identified the key research gaps and proposed a conceptual framework to address the identified gaps to be a reference and guide for organisations adopting blockchain in healthcare.

The effect of three catalysts; subsidy proportion, word of mouth (WOM) and advertising effectiveness is addressed in this piece of work, in addition to a forecast of the power generated and the CO<SUB align="right"><SMALL>2</SMALL></SUB> emissions reduction by 2080. System dynamics (SD) is the fundamental approach of this study. Qualitative interviews and energy reports assisted the data collection process and simulation was conducted between 2020 and 2080. Six scenarios are hypothesised to facilitate the comparison between the catalyst's effects with the help of break-even point analysis. Jordan is expected to generate 1.845 Terra Wh (TWh) and 995.9 TWh of energy by 2040 and 2080, respectively. The CO<SUB align="right"><SMALL>2</SMALL></SUB> emissions reduction is expected to cross 630 million tons by 2080. Advertising effectiveness was found to be the top catalyst that stimulates the power generated in Jordan followed by WOM. The quantitative models foster the policy makers towards investing in social acceptability dimensions toward achieving earlier equivalency of demand and supply. This is the first study in Jordan that develops break-even calculations at various levels of catalysts using SD. Journal: Int.

Due to the lack of coconut tree climbers worldwide, many coconut palm growers are not interested in cultivating coconut farming. Based on the above problem, numerous researchers have developed various climbing mechanisms. To overcome this problem, a novel coconut tree climbing device (CTCD) was introduced which can climb the coconut tree up to the canopy. To check the deformation behaviour and generated stresses of various parts of the device in the present research work, the authors conducted dynamic analysis, such as modal, harmonic, and transient analysis in ANSYS 2021. Moreover, the dynamic properties of each component will also be tested under vibrational excitation. Therefore, one of the vibrational properties, that is, the natural frequency, is used to analyse the effect of transient loads and avoid the noise and vibration hazards in the components of the coconut tree climbing mechanism.

This empirical study combines clustering techniques and RFM model to analyse member customers' transaction data from a database of a supermarket in Taiwan within a six-week period. The results showed that 5,410 member customers are grouped into loyal, new, and vulnerable customers. A one-way analysis of variance is performed to show these three groups of customers are statistically different. This research further explores the top 10 best-selling merchandise items in both purchase quantity and total money spent. Loyal customers need to focus on five merchandise items. New customers have eight out of ten best-selling merchandise items appeared in both purchase quantity and total money spent. Supermarket management need to pay more attention to these eight items for new customers in this supermarket. Journal: Int.

Due to the fact that NEV powertrains are controlled by electrical and/or electronic (E/E) systems, faults and failures of these systems can lead to hazards. In order to prevent such hazards, functional safety engineering aims at avoiding or mitigating safety-critical E/E system faults and failures on the system, hardware and software level. Accordingly, numerous functional safety activities need to be executed and many workproducts are required. Variability of NEVs, high requirements as to achieve functional safety, short development cycles and resource constraints impose challenges for automotive companies. Motivated by an industrial case study we identify variation points of NEV powertrains and analyse their dependencies on the functional safety lifecycle. Based on that, we identify organisational and technical measures which support variant-rich new energy vehicle powertrain functional safety engineering. Journal: Int.

The multiple objective functions are formulated to single CEED constraint to solve using an efficient algorithm. By combining the peculiar preying characteristics of Harris Hawk and the intellectual food storage characteristics of crow, a novel MIHHO Algorithm is designed to handle the CEED constraint. The efficiency of the optimisation strategy is evaluated with six test cases. The minimised results of transmission loss, economic cost and emission cost for the DG system by MIHHO technique is evaluated over the traditional strategies, such as GA, GWO, WOA, CSA and HHOA. From the outcomes, it is evident that the proposed MIHHO algorithm provides better solution as compared over the existing methods. Journal: Int.

Due to the large number of devices, determining the best resource allocation in this situation is challenging. Accordingly, a unique resource allocation strategy for fog computing is suggested in this work. The resource allocation of fog computing is made possible by the modelling of a nonlinear functionality under the objective function comprising metrics like service response rate, execution time, make span, resource consumption, and reboot rate. The proposed approach also takes consideration for the allocation of resources in urgent scenarios that allow for quick resource distribution. Considering this as the optimisation problem, a new optimisation model termed as hybrid coati insisted beluga whale optimisation (HCIBWO) is introduced in this work. The performance of proposed work is evaluated over the conventional models in terms of different measures. Journal: Int.

Lean manufacturing (LM) is a popular method for optimising processes by eliminating non-value-added activities and improving efficiency and flexibility. However, in today's rapidly changing technological and market environment, companies must also adopt innovative production management approaches to stay competitive. The Fourth Industrial Revolution and related technologies offer the opportunity to take current manufacturing systems to the next level. While previous research has explored the concept of 'Lean 4.0', which combines Industry 4.0 and LM, there has been less focus on the relationship between methodological approaches and technological concepts. This research aims to fill this gap by presenting a methodological-technological framework for implementing Industry 4.0 technologies in SMEs in order to achieve the objectives of LM. The proposed methodology, called SDAPI, is developed through a literature reviews, it consists of five steps: specify, detect, analyse, propose, and implement. Journal: Int.

Because of this, the market is more cutthroat for businesses, especially those that are indigenous. Core functional competences are essential for survival in the age of globalisation since they can positively or negatively impact a variety of organisational performance factors. This paper deals with the prioritisation or ranking of the factors, which affect core functional competencies and further affect the performance of the Indian manufacturing industry. For the ranking of the attributes, the fuzzy MAUT method has been used in the study. Journal: Int.

An optimal design problem is being scrutinised and worked upon in the current paper. This work is conducted with reference to prior study conducted by Hu et al. (2012). They used a genetic algorithm (GA) to find the optimal design of the series-parallel configuration consequently minimising its cost. The particle swarm optimisation (PSO) technique is being proposed in this article to further refine their results. The solution entails identifying the vector comprising of system components and repair teams, (<i>n</i><SUB align="right"><SMALL>1</SMALL></SUB>, <i>n</i><SUB align="right"><SMALL>2</SMALL></SUB>, ..., <i>n<SUB align="right"><SMALL>N</SMALL></SUB></i>, <i>r</i><SUB align="right"><SMALL>1</SMALL></SUB>, <i>r</i><SUB align="right"><SMALL>2</SMALL></SUB>, ..., <i>r<SUB align="right"><SMALL>N</SMALL></SUB></i>). These computations were carried out using the computer software Python. As a consequence, extremely intriguing results were achieved. Journal: Int.

To solve the issue, the proposed framework employs the linear programming model (LPM) and TORA software to optimise the entire spare parts inventory. This research offers petroleum and fertiliser industries a clear and straightforward way for the spare parts management. Results show improved cost and stock management that promotes sustainability with optimised data set of total spare parts inventory as 40,000 numbers and US$65.5 million. Additionally, it eliminates the excessive stock due to exaggerated risk with traditional practices and reduces deterioration by lowering long-stay of items in the warehouse. Validation of model is done using classified data sets (as HML and FSN) that are based on previous factual six years' cumulative consumption and acquired from an Indian fertiliser industry.

This paper aims at the optimisation of UA-facility layout in the flexible bays structure (FBS) to maximise the adjacency requirements of facility types for the production layout. The FBS is a most commonly used structure flexible to allocate the facilities in the bays of unequal areas permitting empty space in the total area of the layout. The proposed mixed integer programming model has been formulated to ensure; minimum side length, confined aspect ratio of facility types, and optimal space utilisation in the total area of facility layout. The genetic algorithm based heuristic has been used to search the discrete solution space in a feasible time span. The optimal results obtained are mapped with the best-known numerical instances reported in the literature to approve the efficacy of proposed solution approach. Journal: Int.

Three optimisation methods were used: the Taguchi method, the response surface methodology (RSM), and the non-dominated sorting genetic algorithm II (NSGA-II). The Taguchi method identified the most influential parameter for surface roughness (f > d > s) and for material removal rate (d > f > s). RSM regression models achieved high R<SUP align="right"><SMALL>2</SMALL></SUP> values of 0.9896 for roughness and 0.9997 for material removal rate. NSGA-II multi-objective optimisation produced 35 Pareto solutions within ranges of cutting parameters, resulting in surface roughness values from 0.239 to 3.301 μm and material removal rates from 151.53 to 594.99 mm<SUP align="right"><SMALL>3</SMALL></SUP>/s. Confirmation experiments validated the optimal values, with deviations within 10%, confirming the accuracy of the research method for solving the optimisation problem. Journal: Int.

The uncertainties in failure/repair data of every subsystem/component of the bleaching system are quantified using two types of fuzzy numbers, trapezoidal and triangular fuzzy numbers. The basic arrangement of components/subsystems of bleaching system is represented using Petri net model. The fuzzy values of various reliability metrics of bleaching system for different uncertainty levels have been evaluated employing fuzzy <i>λ</i>-<i>τ</i> technique. Subsequently, to analyse the failure behaviour of bleaching system and to plan for suitable maintenance policies, these fuzzy values have been defuzzified using centre of area method. The analysis is useful for plant managers to improve the performance of bleaching system by establishing and implementing appropriate maintenance strategies and policies. Journal: Int.

Specifically, the K-means clustering algorithm is employed to generate initial routing solutions, subsequently optimised by an artificial bee colony (ABC) algorithm. The new approach is tested on large-scale real-life cases. The computational results show that the new algorithm outperforms a well-established ABC algorithm in terms of both objective value and computation time. In addition, the experiments highlight the importance of considering both the distance between customers and customer time windows in the clustering process to ensure good computational results.

Integrating qualitative and quantitative methods, it employs grounded theory (GT) for synthesising user interview data and iteratively refines design criteria through theoretical coding. The fuzzy analytic hierarchy process (FAHP) and criteria importance through intercriteria correlation (CRITIC) objectively establish weights for design evaluation criteria and finalise the weighting values using the combined ideal point assignment method. The VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is used to evaluate and select design solutions. This comprehensive approach minimises subjectivity and bias in criteria determination and weighting, enhancing the Objectivity and accuracy of cognitive training application evaluations. Usability questionnaires and user testing validate that the integrated approach improves design decisions' objectivity and scientificity, making the application more responsive to user needs.

Products are delivered from facilities to customers directly or via hubs, utilising different transportation modes. Full truckload shipments are employed for delivering products from facilities to customers or hubs, while less than truckload shipments are utilised for products from hubs to customers. Considering the susceptibility of facilities to failure, customers are allocated to either a primary facility exclusively or both primary and secondary facilities, with the secondary facility serving customers only during the failure period. The problem is mathematically formulated as a linear integer programming model and subsequently solved using the Lagrange relaxation procedure. The solution was obtained with an average computational time of 96.6 seconds, demonstrating a gap between upper and lower bounds averaging 0.158%. Journal: Int.

A risk assessment framework has been established to track risk scenarios and to address the level of disruptions on the priority orders of initiatives under the influences of scenarios. It demonstrated in an LPG facility in the State of Kuwait with 17 emergent conditions, 3 scenarios, 15 initiatives, and 4 evaluation criteria. The shutting down of one centre and the shutting down of two centres were the most disruptive scenarios. The highest ranked initiatives are: Increasing the number of workers for inspection, having random weekly inspections, and having monthly maintenance, respectively. However, these initiatives are the least robust to disruptive scenarios' impact. The initiative, raising customers' awareness of how to safely use LPG cylinders, has the least priority ranking order but is the most robust initiative to the influence of scenarios. Journal: Int.

It consumes a significant amount of energy while increases the system's spectrum effectiveness. This paper shows the resource distribution in non-orthogonal multiple access (NOMA) models for IIoT applications from the view of power efficiency. In this paper, the hybrid optimisation is used for reducing the energy consumption of power resources and channel resources. An integrated squid game with coati optimisation algorithm (ISG-COA) is developed by integrating squid game optimiser (SGO) and coati optimisation algorithm (COA) for resource allocation in IIoT scenarios. The limitation of user service quality criteria is also added to the existing optimisation problem in order to prevent the situation where the data transmission quality is substantially impaired as a result of the system's energy-saving measures. The algorithm's average system energy efficiency is higher according to the strategy performance simulation experiment when compared to traditional resource allocation algorithms. Journal: Int.

Considering the user's psychology and demand response, the energy storage behaviour of users is analysed to maximise the benefit of energy storage and achieve a win-win situation for both load aggregators and shared energy storage providers. The pricing and energy supply strategies of microgrid operators are optimised based on carbon capture technology. A case study is conducted on a microgrid system located in a business park in southern China. Through numerical simulation and comparative analysis of multiple scenes, it is verified that carbon capture devices and shared energy storage can significantly reduce the microgrid's carbon emissions and the uncertainty of the system operation and improve users' demand response capability, which is beneficial to the long-term development of the microgrid system.

The technology enables wide variety of materials to be printed for different applications starting from automotive, aerospace, marine and to the biomedical fields. 3D printing processes are majorly used to print polymeric materials compared to metallic materials. Polylactic acid (PLA) is the most commonly used material by the fused deposition modelling technique, which accounts for multiple applications. The present study investigates the effect of printing parameters such as infill density, wall thickness, printing speed and ironing to identify optimum process parameter combination for better mechanical performance. Based on the design of experiments, 40 samples were printed and measured for mechanical characteristics. Upon the analysis using TOPSIS, at the parameter combination of infill density (99%), wall thickness (3 mm), and printing speed (150 mm/hr), the printed specimens showed higher tensile strength of 10.20 MPa and comparatively good surface finish. Hence, the parameter optimisation showed a positive influence on enhancing the mechanical properties of printed components. Journal: Int.

However, a comprehensive framework and assessment criteria for integrating emotional factors into the design of such medical products are lacking. To standardise these criteria, this study integrates emotional design theory, grounded theory, and the fuzzy analytic hierarchy process (FAHP). Firstly, based on the three-level theory of emotional design, an interview outline was constructed to conduct semi-structured interviews with the target users, and the interview content was coded and analysed using the grounded theory to refine the emotional factor design indicators. Subsequently, FAHP assigned weights to these indicators, constructing a comprehensive emotional factor application model. PSSUQ validated product usability, revealing that the proposed model effectively meets users' emotional needs, thereby standardising emotional factors application criteria and offering theoretical references for designing medical products for paediatric asthma.

A case study approach is applied to a manufacturing company in Uzbekistan. Four steps are carried out: selection of a case company; formation of a working team and definition of the current process mapping; selection of relevant key performance indicators and lean tools; implementing lean tools and assessing improvements. The total daily production rate of the case company increased by about 28% after lean application. Developing countries need special efforts to overcome the barriers related to the cultural background of companies and the mentality of their employees, in order to support the diffusion of lean manufacturing. This case study can stimulate academics to focus on further research on the application of lean tools in developing countries and the key contextual factors for its successful implementation.

The locomotive maintenance organisation considered in this study has over the years hold excess obsolete and non-use inventories used for locomotive maintenance owing to poor inventory management practice. Hence, in order to remedy this dilemma, this study investigates strategies that could be deployed to generate value from the excess inventories held in the organisation. Experts' opinion sourced from inventory planners and supplier chain managers, and literature information were used to unveil suitable strategies that could be used to generate value from the excess inventories held in the organisation. The result of this research exercise revealed that lateral transshipment, auctioning, sales to external organisations, repurposing and supplier buy-back are the suitable strategies that could be used to generate value from the excess inventories held in the locomotive maintenance organisation.

Hence, this study examines how MBMA impacts each MC capabilities, thereby enhancing competitiveness of the manufacturing industry. Hypotheses were developed following a thorough review of the literature on manufacturing capabilities and modularity-based manufacturing. Expert opinions were collected using structured data-collection tools, and analysis was conducted using the algorithms of the fuzzy Delphi method. The research findings indicate that applying an MBMA in MC strategy enhances MC capabilities and ultimately contributes to increasing the competitiveness of the manufacturing industry. Journal: Int.

The production scheduling process allocates resources such as time for each specific operation, detects possible conflicts of allocated resources, controls job release timings on the shop floor, ensures delivery due dates, and thus increases the productivity and efficiency of the workforce. In this paper, a method usually exploited to reduce the production duration, dubbed 'lot streaming', is adapted and applied to solve scheduling problems in open shop environments. A new integer linear programming (ILP) model is developed to outline the integration of lot streaming scheduling and constraints of partial functionality machines in an open shop environment to minimise the makespan. In such an environment, there are no restrictions on the order in which the machines perform the job's operations. The developed model is applied and tested on five different hypothetical problems. The experimental results are presented, and the efficiency of the proposed ILP is discussed. It is concluded that considerable reductions in the makespan can be achieved with the inclusion of lot streaming in an open shop production environment. Journal: Int.

To meet the study objective, definitive screening design (DSD) and ANOVA techniques were used to develop a predictive model for establishment of a functional relationship between the selected process parameters and part surface roughness. Thereafter, the predictive model was validated and optimised using genetic algorithm (GA) technique. The comparison of optimal and default process parameter settings showed an improvement in surface roughness of 60.9%. The proposed combined DSD-GA approach can assist practitioners in fabrication of various industrial products to uplift the additive manufacturing (AM) sector. Journal: Int.

Mass customisation (MC) has emerged as a solution to tackle these challenges by offering customised products while maintaining product cost, quality, volume, variety, and delivery time, which are called competitive factors in the manufacturing industry. However, the effectiveness of the MC strategy depends on how effectively the industry applies different manufacturing systems. Therefore, the main objectives of this research were to identify and determine how the manufacturing system enhances MC capabilities and contributes to the competitiveness of the manufacturing industry. The process involved formulating hypotheses after reviewing existing literature and gathering expert opinions and analyses using the algorithms of the fuzzy Delphi method. Ultimately, this study identified the basic manufacturing systems that can increase MC capabilities, which contributes to improving the competitiveness of the manufacturing industry. Journal: Int.

Traditional two-dimensional design methods are inadequate for accurately conveying three-dimensional structures, textures, and product intricacies, This study presents an immersive packaging design system that leverages VR and deep learning-based semantic segmentation to address these limitations. The system was developed through a structured approach involving framework analysis, extensive data preparation, model training, and the creation of interactive VR environments. A user study with 50 participants demonstrated significant improvements in comprehension (average score: 4.2 vs. 3.0), satisfaction (4.0 vs. 2.8), engagement (4.1 vs. 2.5), and task efficiency (15 minutes to 10 minutes). An empirical case with a beverage brand further validated its effectiveness, showing increased consumer satisfaction, understanding, engagement, purchase intent. These results underscore the system's potential to enable intelligent, personalised, and immersive packaging design experiences. Journal: Int.

Optimal antenna design ensures better results in almost all applications. Hence, this paper aims to introduce a novel Microstrip patch antenna design optimisation that ensures enhanced antenna performance with the optimal design parameters like substrate thickness, width, height, and length, under the satisfaction of multi-objectives like gain, bandwidth, antenna efficiency, return loss, and TARC. To solve the given optimisation problem, this work implements an arithmetic adopted chimp optimisation algorithm (AAChOA) scheme that merges the strategy of the chimp optimisation algorithm (ChOA) and arithmetic optimisation algorithm (AOA) to obtain higher antenna performance. Finally, the proposed technique was evaluated over other extant models based on different parameters like antenna gain, efficiency, total active reflection coefficient (TARC), return loss, and bandwidth.

Here, the optimal routing is performed by selecting the cluster head under certain constraints like delay, distance, QoS, RSSI, and security. For this, chaotic functions influenced spider monkey optimisation (CFISMO) algorithm is used. The assignment of channels as the scheduling policy is introduced through senders while it has packets to transmit. In this work, the channel assignment will be initiated via a machine learning model that predicts the availability of the channels, which is based on the paths (channels) generated under the selected cluster head. Here, an optimised neural network (NN) will be used. Thus, the final output shows the paths (channels) to be assigned for data transmission. In the end, the performance of the adopted routing approach is evaluated over other traditional schemes based on various metrics like distance, PDR, delay, energy, alive nodes, QoS, security, and trust, respectively.

Floor planning is done to ascertain the relative location of the various modules inside each sub-circuit after the complex circuit is divided into smaller sub-circuits during the partitioning stage. The objectives of this process are to minimise the total chip area covered by the circuit, the amount of dead space in the layout, and the interlinking wire length (WL) among modules. Estimating the placements and forms of the modules is what it is all about. The integrated circuit (IC), which has small feature sizes, a high clock frequency, and high packing density, can dissipate a lot of heat. This work proposes a self-adaptive cat swarm optimisation (SA-CSO) to resolve the floor plan issues. The non-slicing floorplans are regarded by the algorithm as having hard modules with continuous outline restraint. Thus, the area of layout gets reduced. Journal: Int.

The simulation of IoT is the first step carried out, where the nodes collect the breast cancer histopathological image of patients. The routing is established with child circle inspired drawing optimisation (CCIDO). The fitness function is considered for choosing the best route using energy, trust distance, and delay. Then, the multi-grade breast cancer is executed at the base station. Here, a median filter is utilised for abandoning the noise. Unified extraction of features is provided for acquiring the features. The classification of breast cancer is done with the LeNet and trained using CCIDO. The assessment was performed to reveal the importance of the proposed model. The CCIDO-LeNet outperformed with the highest accuracy of 94.9%, NPV of 93.4%, PPV of 93.3%, TNR of 93.9% and TPR of 94.8%. In future, other datasets can be engaged to validate model flexibility.

The SURF features have been extracted from the audio input and text input. In addition, the video input is converted into RGB to greyscale format, and then the SURF features are extracted from it. The pattern generation phase includes three stages: 1) scaling of features; 2) rules generation with Association rule mining algorithm; 3) optimised rule generation. Initially, the extracted feature is scaled within limits 1 to 20, and the rules are generated for the video, audio, and text signals separately using the Association rule mining algorithm. Moreover, the optimised rules are generated from the extracted rules using the improved GOA model. Then, using the map-reduce framework, the correlation between them is validated. Journal: Int.

To address this challenge, a novel mixed integer nonlinear model is formulated by incorporating internal quality costs, environmental impact considerations, and the impact of buffer size to solve the micro-computer aided process planning problem. The scope covered is limited to milling operations for a part mix involving different materials being machined. Surface roughness is used to evaluate the desired quality level of finish. The internal quality failure cost model, including scrap and rework, is developed based on Taguchi's quadratic loss function. Mathematical programming is employed to validate the results of genetic algorithms (GAs). Because of the nonlinear nature of the model, GAs has been used. Considering strict quality cost measures, the model minimises internal quality-related costs while minimising the environmental impact. Journal: Int.

The trending problem relies on the demand prediction of RES, such as wind, solar, and the IEEE-30 bus system, which is assessed using the ANN classifier. The evaluated values are fed as input to the proposed optimisation algorithm known as the BE-Cro optimisation algorithm. Here, the optimisation variables are controlled to achieve the solution for the EED problem, to reduce the entire cost. The performance of the BE-Cro method is evaluated based on cost of economics, cost of emission, power loss, and total cost. The result depicts that the BE-Cro method is superior in performance when compared to other traditional methods. In future, the analysis will be carried out in IEEE-33 and IEEE-69 bus systems.
