  • Application of Interactive Fuzzy Goal Programming for Multi-Objective Integrated Production and Distribution Planning   Order a copy of this article
    by Md. Sanowar Hossain, Md.Mosharraf Hossain 
    Abstract: Integrating two interconnected processes and controlling conflicting goals of a production and distribution problem is necessary for better planning. The aim of integrated production-distribution model is to allocate the limited available resources and equipment to produce the products over the time periods and ensure economical dispatching the products to the distribution centers or retailers. Using deterministic models in such conditions may not lead to fully satisfying results because the related parameters like market demands and capacities in production environment and processing times are frequently fuzzy in nature. In a responsiveness and competitive market, production and distribution planning modules have been considered in the framework of satisfaction level of decision maker. To make such problems realistic, triangular fuzzy numbers and the concept of minimum accepted level method are employed to formulate the problem. Minimum operator and weighted average operator method is used to aggregate all fuzzy set of the problem and solved by three algorithm and goal programming method. The proposed approach aims to formulate a fuzzy multi-objective linear programming model to simultaneously minimize the total production cost, distribution cost and delivery time for multi-product and multi-time period in a supply chain under multiple uncertainty condition. The Analytical Hierarchy Process (AHP) is used to rank multiple objectives to make the problem more realistic for the respective case and problem solved by using Matlab software.

    by Suman Gothwal, Tilak Raj 
    Abstract: The evaluation of the most appropriate performance measures in the manufacturing sector is one of the strategic issues that may affect the Flexible Manufacturing System (FMS). In this paper, five areas of performance measures, i.e., measures related to finance, measures related to customers, measures related to innovation and knowledge, measures related to internal business and miscellaneous measures with their sub-measures are considered. The purpose of this paper is to provide a framework to proactively manage performance measures. For this purpose, a comparative study of multi criteria decision making approaches, Simple Additive Weighting (SAW) and Weighted Product Method (WIP) are integrated with Analytic hierarchy process (AHP) in order to get the best solution. AHP is used to determine the weights of the measures which are used in SAW and WPM approaches, for prioritizing the performance measures so that management could take the decision regarding improvement. Here, fuzzy logic is used to change the qualitative measures into the quantitative measures.

    by Ankur Sharma, Rajiv Kumar Sharma 
    Abstract: In recent years, the Cellular Manufacturing System has emerged as an integral part of management ideology and received much recognition and adoration in numerous countries. Many organizations are adapting Cellular Manufacturing Systems to apt the challenges enforced by dynamic customer demands, international competition and assist managers in reiterating to the dynamic environment in an impressive and effectual manner. The primary objective of this paper is to develop a model for the enablers supporting the implementation of Cellular Manufacturing Systems with the help of Interpretive Structural Modelling methodology. These enablers were dissected through literature review and experts opinion. The questionnaire based review has been accomplished for the ranking of these enablers. The MICMAC analysis has been performed to interpret the mutual dependencies of driving enablers (i.e. which help to accomplish other enablers) and dependent enablers (i.e. which are accomplished by driving enablers). From the outcomes, it has been observed that improved production process stability and capability, increased automation, and improved worker skill flexibility forms lowest level in the ISM hierarchy. These enablers have high driving power and low dependence power. So, these enablers may be treated as the key enablers. These key enablers would avail the management in contributing appropriate supervision and guidance during the successful implementation of Cellular Manufacturing System.

    by Santosh Kumar Nayak, Purna Chandra Mishra 
    Abstract: Response surface methodology was employed for optimising the complex air-water spray mechanisms that occur in hot surface cooling processes where forced convection exists. Results from a physical air-water spray cooling experiment were generated and the experimental parameters were optimised for achieving heat flux from the surface of a hot steel test plate of dimension 120 mm X 120 mm. The thickness of the plate was considered as one of the variable (4 mm, 6 mm and 8 mm) during the experimentation. The other variables in the problem were the nozzle to plate distance, air pressure and water pressure. The experiments were carried out based on the response surface design of experiments. The heat flux was calculated by using Newtons convection model. The optimization of the controlling parameters was carried out by using the Response Surface Method (RSM). A new mathematical correlation was developed for optimization of the surface heat flux.

    Abstract: The purpose of this study is to evaluate the performance of emergency departments. The multi-criteria comparison between the wards of different hospitals is not only useful for the patients but also important for the hospitals management to improve their performance and for the medical policy makers to plan strategic decisions. In this paper, it is intended to consider the aspects of efficiency beyond the traditional evaluation of check list. The factors which have been chosen are divided into two subsets: first, input factors consisting of no. of active beds, no. of physicians, no. of nurses and medical equipment and second, output factors including no. of discharge, percentage of revival, average waiting time and patient satisfaction. The input oriented and constant returns to scale model of Data envelopment analysis (DEA) technique is used to evaluate the efficiency of each Emergency department. The model can be used to find out the causes of inefficiency and how to improve the performance. The method has been applied to evaluate and compare 24 ED of hospitals in Isfahan. DEA model reveals that 37 percent of them are inefficient. The results may be then used to suggest the improvement strategies based on the input factors.

    by J. Gokulachandran, R Padmanaban 
    Abstract: Predicting the remaining useful life of the partially degraded components and putting them to use will help to save natural resources to a great extent. This will reduce the overall cost , energy and protects environment. High productivity cutting tools used in manufacturing industry are generally expensive. As such, the accurate assessment of remaining useful life (for reuse) of any given tool is of great significance in any manufacturing industry. The main objective of this research is to develop a comprehensive methodology to assess the reuse potential of carbide-tipped tools. This paper presents the use of three soft computing methods, namely, artificial neural network, neuro fuzzy logic and support vector regression methods for the assessment of remaining useful life (RUL) of cutting tools. In this work, experiments are conducted based on Taguchi approach and tool life values are obtained. Tool life values are predicted using the aforesaid three soft computing methods and RUL obtained from these values are compared. It is found that the predictive neuro fuzzy method is capable of giving a better prediction of remaining useful tool life than the other methods.

  • The Application of Overall Equipment Effectiveness to Support the Development of a Steamless Nut-Separated Palm Oil Mill   Order a copy of this article
    by Tanakorn Tantanawat, Nuttharporn Puckdeesorasuk, Arkom Haewchin, Ekkarut Viyanit 
    Abstract: A steamless nut-separated palm oil mill has been developed based on small-scale communitys requirements with the purpose to overcome constraints faced by a conventional palm oil mill. The current paper discusses challenges in the development and technology transfer of the steamless nut-separated palm oil mill, including communication about technology performance, uncategorized problems, and limited flow of financial information. To overcome these challenges, the proposed approach is to use OEE-based plant performance indices and its estimated corresponding financial performance indices to communicate about the technology performance. In this work, the calculation of OEE was derived based on data obtained from palm oil mills. In addition, the performance factor was sub-categorized into the reception and extraction factors to relate the plant performance to the mill capacity and oil extraction rate, which are common variables used in palm oil mills. Moreover, the quality factor was derived based on free fatty acid of crude palm oil. A simulated plant operating data was used for the purpose of demonstrating the proposed approach. The figures of world-class OEE and its components were also used to identify the area for initiating process improvement activities and estimate the potential performance of the technology.

  • Measurement of Overall Equipment Effectiveness to Improve Operational Efficiency   Order a copy of this article
    by Rohit Kr Singh, Elvin Clements, Vandana Sonwney 
    Abstract: This paper presents measurement of OEE which serves a basis for analyzing operational efficiency in a manufacturing unit. Initially, measure of overall equipment effectiveness is described which explains what metrics make up this OEE and the losses that are classified under each of the metrics. Then it focuses on how OEE forms an integral part of the total productive maintenance activity. Its use and implementation in the manufacturing unit are analysed by calculating the OEE before and after making some modifications in the process by considering the case of die manufacturing equipment. Later, the significant benefits of developing OEE as basis for operational measure are described. The purpose of the paper is to explore the use of OEE not just as an operational measure but also as an indicator of process improvisation within a manufacturing environment. The losses of the equipment are identified and measures are suggested to improve it. The methodology adopted for this paper tries to provide an independent assessment of OEE effectiveness as a measure of operational improvement. This case study with longitudinal approach includes data collection and analysis of the process followed in a manufacturing unit. The operational data of OEE variables is collected that contribute in calculating availability, performance and quality which are the criteria for measuring OEE. It also illustrates how the three OEE factors are determined and splits them into the specific constituents that are needed to develop the OEE percentage. The OEE measure is analyzed but assessed from an overall systems level. It illustrates how the three OEE Factors are calculated and breaks them into the specific elements that are required to develop the OEE percentage. The equipment effectiveness is calculated before the implementation of the TPM and after the implementation. The method is divided into steps which bring improved maintenance policies. The continuous and thorough inspection of the production procedure is achieved through measurements of the overall equipment effectiveness. The OEE thus obtained is compared with World class OEE and measures are suggested to attain on par OEE level. The Current study will enable industry to monitor the OEE and the suggested steps if implemented will lead to improved process and performance of the equipment.

  • An Automated Method for the Construction of Semantic Business Process Patterns   Order a copy of this article
    by Makni Lobna 
    Abstract: The effectiveness of reuse in the development of software prompted researchers to look for reuse techniques for business process modeling. Indeed, a variety of reusable business artifact types has been proposed during the last decade. Among the recently proposed reuse artifact types, Semantic Business Process Patterns (SB2P) offer process patterns that encapsulate knowledge and commonly used practices in a particular domain. The design using an SB2P provides for the adaptation of these practices and it offers guidance on possible variations. This paper presents an automated method to construct SB2P starting from a set of process models in a given domain. The proposed method has the merit of accounting for the semantic, structural and behavioral information of the initial models. In addition, it produces process patterns where common fragments are distinguished from variation points, which assists business process designers in reusing an SB2P to meet their requirements. The method is illustrated through a case study in the cost accounting domain.

  • A farmland choice based on hesitant fuzzy linguistic preferences relations   Order a copy of this article
    by Nesrin Halouani, Sonia Hajlaoui 
    Abstract: A new type of fuzzy preference structure, called hesitant linguistic preference relations is developed in order to describe uncertain evaluation information in group decision making (GDM) farmland choice. Moreover, it allows decision makers to offer all possible linguistic terms that are not accounted in current preference structure types when we compare two alternatives. Systematic aggregation operators are proposed to aggregate hesitant fuzzy linguistic information. In addition, an approach to GDM based on PROMETHEE method concepts and hesitant linguistic preference relations is developed to take into account the differences in opinions between individual decision makers. An agriculture real case study is implemented to demonstrate the practicability of the proposed method. Also, a sensitivity analysis is carried out to reveal the effect of the criteria weighting variations on the originally obtained ranking.

  • A Reliability Centered Maintenance Approach for Assessing the Impact of Maintenance for Availability Improvement of Carding Machine   Order a copy of this article
    by Aniket Thawkar, Pravin Tambe, Vishwas Deshpande 
    Abstract: The complex nature of modern equipment and systems often leads to failures and as a consequence increase in machine downtime, thus affecting production. The failures of machines cause disruptions in production, resulting in the loss of availability of the system and increase the cost of maintenance. This paper presents a Reliability Centered Maintenance (RCM) methodology to improve the availability of carding machine in textile industry. The main objective of this paper is to present a RCM approach for improving the availability of the carding machine and thus maximize the production output. Failure Mode and Effect Analysis (FMEA) is used for analyzing the failures in the machine. The preventive measure to reduce the failure frequency and its impact are proposed. The proposed preventive measures results in reduction of about 26 % of the total downtime and availability improvement of approximately 1.7 %, as compared with the availability due to current maintenance practices.

  • A graph-theoretic based meta-heuristic algorithm for solving cooperative dynamic facility layout problems   Order a copy of this article
    by Masume Messi Bidgoli 
    Abstract: The Dynamic Facility Layout Problem (DFLP) is related to location of all facilities of a plant in a dynamic environment. Most of the existing models for this problem ignore competitive or cooperative reactions to ones action. In a recent work, the assumption of independency between parameters of material handling cost function has been relaxed and a game model has been presented. Two main shortcomings exist in this work. In one side, cooperation between decision makers is ignored. This matter could result to remove some better solutions that are not Nash equilibrium. In other hand, computing Nash equilibrium takes much time. Then, Nash equilibrium maybe results in expensive solutions in cooperative conditions. In this paper, this real assumption is considered and by modeling the problem as a multi-criteria shortest path problem, a Pareto optimal solution is obtained. The numerical experiments confirm the effectiveness of the proposed model and solution method.

  • A Framework to Enhance Cellular Manufacturing System: A Total Interpretive Structural Modelling (TISM) Approach   Order a copy of this article
    by Sanjay Kumar, Vasdev Malhotra, Vikas Kumar 
    Abstract: The cellular manufacturing (CM) has been proved as a well-known manufacturing strategy that helps to improve manufacturing efficiency and productivity by utilizing the philosophy of group technology. Cellular Manufacturing (CM) has been emerged as a strong approach for improving operations in batch and job shop environments. In cellular manufacturing, Group Technology is used to form part families based on similar processing requirements. It has often been said that the strength of any country resides in the strength of its industrial sector and progress in industrial society has been accomplished by the creation of new technologies. The implementation of cellular manufacturing system (CMS) requires careful planning at all levels of the organisation to ensure that the implementation will achieve the intended goals considering the multiple criteria. Purpose- To identify and analyze the interactions among different enablers of cellular manufacturing system (CMS). The existing enablers available in the past literature are scattered and not able to meet specific requirements of the customers. So, it becomes a necessity to encapsulate these enablers in appropriate proportions to enable traditional organizations to CMS. To fill this gap total interpretive structural modelling (TISM) and MICMAC analysis based framework model has been developed to understand the mutual interactions between among the enablers. Design/methodology/approach- Identification of enablers followed by application of TISM which is an innovative version of ISM and MICMAC analysis used to study and analyze the mutual interactions between identified enablers. Findings- The result reveals that top management support, organizational structure and information technology integration have strong driving power and weak dependence power and are at the lowest level in the TISM model hierarchy, while the outcome enablers of CMS have low driving power but have high dependence power. Research limitations/implications This model is developed on the basis of inputs from few experts and may not reflect the opinion of whole industry community. Practical implications Top management must stress on enablers having strong driving power for efficient implementation of CMS. Managers in the area of manufacturing may drive useful insights from the empirical study presented in this paper. Managers should plan an effective strategy for proper implementation of CMS which make organization more flexible, productive, competitive and profitable. Originality/value TISM based framework structural model have been proposed for industry or organization which is a new effort for implementation of CMS.

    Abstract: At current situation, LM has grown to be a worldwide trend. This is a tentative study of lean manufacturing implementation in Indian industries. A questionnaire survey has been deployed to evaluate the contributions of lean manufacturing in Indian Manufacturing Industry. The analysis was executed on thirty four Indian manufacturing organizations. All the respondents were selected from those organizations that are committed to imbibe various lean manufacturing practices. The study reveals that nearly all of the selected respondent firms are categorized as an evolution on the way to lean manufacturing practice and the organizations have paid more attention towards organization operation and management, narrate to external relationships with suppliers and customers through various parameters. Such organizations think that the issues that drive lean manufacturing implementation include customer focus and organizations ability to holistically imbibe continuous improvement initiatives. The results of this study have revealed that the major difficulty to implement lean manufacturing system in an organization is the lack of understanding lean concepts and lack of appropriate understanding about lean techniques adopted by the organizations.

    by Parames Chutima, Krit Prasert 
    Abstract: This paper presents a novel algorithm which modifies the coincident algorithm (COIN), namely the adaptive extended coincident algorithm (AE-COIN), to solve a multi-manned assembly line balancing problem (MALBP). The multiple objectives are optimised in a hierarchical manner comprising of the following objectives: (1) minimise the number of workers, (2) minimise the number of stations, and (3) balance workloads between stations and maximise work relatedness. The objectives in the third hierarchy are optimised in a Pareto sense since they are conflicting in nature. The performances of AE-COIN are compared against well-known algorithms, i.e. BBO, NSGA II and DPSO. The experimental results show that AE-COIN outperforms its contestants in both solution quality and diversity.

  • Designing and planning a sustainable supply chain network considering economic aspects, environmental impact, fixed job opportunities and customer service level   Order a copy of this article
    by Alireza Taheri-Moghadam, Jafar Razmi, Mohammed Fazle Baki 
    Abstract: In this paper, a sustainable supply chain (SSND) problem is developed which contains economic aspects, environmental issues, social impacts and customer service level. The economic objective is minimizing total cost of the whole network (production, transportation, inventory holding/ stock-out and investment). CO2 emission is considered as environmental issue and the social objective is fixed job opportunities. The customer satisfaction objective contains lead time and stock-out ratio. All of the objectives are in contrast and there is a need for using multi-objective approaches for solving the problem. Normalized normal constraint method is used to capture trade-off between objectives. Simulated numerical examples are considered to evaluate the model and solution approach. Impact of some parameters on customer service level is analyzed by sensitivity analysis. The results show that the proposed model performance is acceptable and it can prepare good managerial decisions for real cases by considering four aspects of business environments simultaneously.

  • Organizational and inter-organizational competencies for supply chain integration   Order a copy of this article
    by Krishnapriya Vankireddy, Rupashree Baral 
    Abstract: The purpose of the paper is to integrate human resource management with supply chain management through examining the role of inter-organizational competencies (information sharing (IS)) as a mediator between the organizational competencies (cross-functional information sharing, participative culture and learning orientation) and supply chain integration (SCI). To test the hypotheses of interest, data were collected on 80 manufacturing firms from India through a structured questionnaire and analyzed using Partial Least Squares method (PLS). The findings revealed that participative culture and learning orientation were positively related to SCI and were fully and partially mediated by IS respectively. The study provides evidence for linking competencies with SCI in the literature that are otherwise scarce in the form of empirical studies in the context of supply chain. It also succeeds in examining the role inter-organizational competencies as a mediator, thus providing insights into such competencies. The study is also one of the first in studying competencies required for supply chain integration in the Indian context.

  • Measuring the Efficiency of Community Colleges Using Super Efficiency Approach for the Case of Non-discretionary Factors in Data Envelopment Analysis with Sensitivity Analysis   Order a copy of this article
    by Mushtaq Taleb, Razamin Ramli, Ruzelan Khalid 
    Abstract: Malaysian community colleges play a significant role in achieving Malaysias vision to be a developed country in 2020. For this reason, their efficiency should appropriately be measured. However, their efficiency measurement using a conventional Data Envelopment Analysis (DEA) model is not appropriate since some of their inputs; e.g., entrant and enrolment students are non-discretionary while a part of output of their graduate employability is discretionary. This paper thus proposes an alternative approach of super efficiency slack based measure for the case of non-discretionary factors in DEA. The proposed approach was used to evaluate the efficiency of 25 main campuses of Malaysian community colleges from 2012 to 2013. The results support the decision maker of Malaysian community colleges to discriminate and rank efficient and inefficient community colleges in the presence of both super efficiency and non-discretionary factors. The significance of inputs-outputs on efficiency status was tested by sensitivity analysis.

    by Kewal Krishan Nailwal, Deepak Gupta, Kawal Jeet , Sameer Sharma 
    Abstract: An improvement heuristic algorithm is proposed in this paper for solving flow shop scheduling problem. To test its efficiency, firstly the performance of the proposed algorithm is done against the six heuristics existing in the literature including the best NEH heuristic on 120 Taillard benchmarks. Further, this set of 120 Taillard instances is increased to 266 benchmark problem instances which include Carliers, some Reeves and some new hard VRF instances from Vallada et al. [New hard benchmark for flowshop scheduling problems minimizing makespan. European Journal of Operational Research. 2015; 240: 666-677]. On these instances, the performance of the proposed algorithm is tested against the best NEH and the famous CDS heuristic with the best known upper bounds. Further, a brief analysis of the other heuristics and metaheuristics existing in literature is done on Taillard problem instances. The proposed heuristic outperforms all the heuristics reported in this paper.

    by P. Rajadurai 
    Abstract: This paper deals with steady state analysis of single server priority retrial queue with Bernoulli working vacation, where the regular busy server can be subjected to breakdown and repair. There are two types of customers are considered, which are priority customers and ordinary customers. As soon as orbit becomes empty, the server goes for a Working Vacation (WV). The server works at a lower service rate during working vacation period. If there are customers in the system at the end of each vacation, the server becomes idle and ready for serving new arrivals with probability p (single WV) or it remains on vacation with probability q (multiple WVs). Using the supplementary variable technique, we obtained the steady state probability generating functions for the system and its orbit. Important system performance measures, the mean busy period and the mean busy cycle are discussed. Finally, some numerical examples are presented.

    by Alka Arya, Shiv Prasad Yadav 
    Abstract: In this paper, we develop optimistic and pessimistic models using fuzzy data envelopment analysis (FDEA). We find the fuzzy optimistic and fuzzy pessimistic efficiencies by using the -cut method. By using super-efficiency technique, we develop models to obtain the complete ranking of the DMUs when fuzzy optimistic and pessimistic models are considered separately. Further, to rank the DMUs when both fuzzy optimistic and pessimistic models are taken simultaneously as hybrid approach. To address the overall performance using fuzzy optimistic and pessimistic situations together in FDEA, we propose a hybrid FDEA using -cut efficiencies decision model. Finally, these developed optimistic and pessimistic FDEA models and ranking models are illustrated with two examples. The proposed model is applied to a real world problem of health sector. We determine the performance efficiencies of hospitals in Meerut district, Uttar Pradesh state, India for the calendar year 2013-2014 using the proposed model. Number of health superintendents and number of health workers are taken as input variables, and number of inpatients and number of outpatients as output variables.

    by Rajeev Kumar, Madhawanand Mishra 
    Abstract: To cater to dynamic and variable performance matrices, manufacturing industries use automation tools and technologies to impart manufacturing flexibility in its processes. To successfully cater to its performance, manufacturing requirements should be designed into the system and then appropriate planning and operational policies need to be followed to support it. This research work validates this using an industrial size Flexible Manufacturing System (FMS) as a multi node manufacturing framework having eight machines. While FMS design spectrum is modeled by different levels of its Routing Flexibility (RF) and number of pallets (NP), planning and operational strategies are implemented through various combinations of Dispatching and Sequencing rules (DR/SR). This work is a simulation study to evaluate FMS performance for which Make Span Time (MST) and machine utilization have been used as a performance metric. This research provides a framework for the decision makers in identifying the appropriate levels of routing flexibility, number of pallets and appropriate combination of dispatching and sequencing rules for optimizing system performance under a given manufacturing environment.

  • Quantifying the influence of FMS on the productivity of a firm   Order a copy of this article
    by Sandhya Dixit, Tilak Raj 
    Abstract: The manufacturing organisations adopt Flexible Manufacturing Systems to meet the challenges imposed by todays volatile market standards. An FMS is designed to combine the efficiency of a mass production line and the flexibility of a job shop to produce a variety of products on a group of machines. Productivity is a key factor in a flexible manufacturing system performance. Despite the advantages offered, the implementation of FMS has not been very popular especially in developing countries as it is very difficult to quantify the factors favouring FMS implementation. For its successful implementation, technological considerations, cost justification as well as strategic benefits are to be weighted. Therefore an attempt has been made in the present work to identify and categorize various productivity factors influenced by the implementation of FMS in a firm, further these factors are quantitatively analysed to find their inhibiting strength using Graph Theory Approach (GTA). GTA is a powerful approach which synthesizes the inter-relationship among different variables or subsystems and provides a synthetic score for the entire system. So using this approach a numerical index is proposed in this work to evaluate and rank the various productivity factors so that the practising managers can have better focus.

  • Optimal Sequencing of Part Families and Configuration selection for process improvement in Reconfigurable Manufacturing System   Order a copy of this article
    by Kamal Kumar Mittal, Pramod Kumar Jain, Dinesh Kumar 
    Abstract: Reconfigurable manufacturing systems (RMS) are considered as next generation manufacturing systems that are capable of providing the functionality and capacity as and when required. Products are classified into several part families as per customer requirement and each of them are a set of similar products. In a shop floor, the manufacturers have to deal with varied number of orders for multiple part families and after completing the orders of a particular family, they need to change over to the orders of a different part family. Shifting from one part family to another may require the systems reconfiguration, which is a complicated method and requires tremendous cost and efforts. The complexity, effort and cost from changing one configuration to another depends on the existing initial configuration and the new configuration required for subsequent production of orders belonging to a different part family. There are different models available for process improvement This paper focuses on determining optimal sequencing of part families formation and configuration selection for process improvement in RMS on the basis of minimum loss occurred for a given system configuration. The proposed methodology is explained and an example is given for illustration.

  • A novel hybrid model for selection of benchmarking technique in Indian service industries   Order a copy of this article
    by Bhupender Singh, Sandeep Grover, Vikram Singh 
    Abstract: The necessity of industries for ascending their standards in competitive market occurs in convention of benchmarking techniques and to adopt new modern methods for effective system. The rationale of this study is to review the benchmarking techniques, moreover to rank them on the basis of applications in service industries. The authors have done abundant survey which identified seven different benchmarking techniques for Indian service industries. Thus, it becomes more complex to select the best one of the benchmarking techniques for implementation in industries. To rank the different benchmarking techniques, a hybrid methodology of analytical network process (ANP), technique for order preference by similarity to ideal solution (TOPSIS) and multi-objective optimisation on basis of ratio analysis (MOORA) is used. A novel hybrid model of these three MCDM is applied for prioritising the benchmarking techniques in the Indian scenario. With application of hybrid model, ranking of best alternative is obtained with fewer calculations and simple validation. Thus, endeavour has been made by authors to give a model for evaluation of benchmarking techniques through MCDM approaches which gives confidence for executives to adopt benchmarking for achieving their goals in their industries.

    by Sanjay Kumar, Vasdev Malhotra, Vikas Kumar 
    Abstract: The cellular manufacturing (CM) has been proved as a well-known manufacturing strategy that helps to improve manufacturing efficiency and productivity by utilising the philosophy of group technology. Cellular manufacturing (CM) has emerged as a strong approach for improving operations in batch and job shop environments. In cellular manufacturing, group technology is used to form part families based on similar processing requirements. Cellular manufacturing systems (CMSs) are those systems which are capable to meet the requirements of modern manufacturing industries. But adoption and implementation of CMSs is not an easy task. There are certain barriers which not only influence the implementation process but also influence each other. The main objective of this paper is to identify and analyse these barriers. In the present work, these barriers have been identified through the literature, their ranking is done by a questionnaire-based survey and interpretive structural modelling (ISM) approach has been utilised in analysing their mutual interaction.
