  • Evaluation of TPM Strategies for Manufacturing Performance Improvement of Indian SMEs for Strategic Success   Order a copy of this article
    by Abhishek Jain, Harwinder Singh, Rajbir S. Bhatti 
    Abstract: Performance improvement of Indian organizations plays a vital role to survive in this competitive era. Indian Small & Medium Enterprises (SMEs) are the heart of large organizations because every large organization is purchasing a number of components from SMEs. Now-a-days, it is very essential to find the appropriate improvement strategy to implement in Indian SMEs for their manufacturing performance improvement. In this study, the authors have made a qualitative model to find the preferred improvement strategy (TPM Strategies) for implementing them in Indian SMEs by using an Options field methodology (OFM), Options profile methodology (OPM), Analytic Hierarchy Process (AHP) and Fuzzy set theory (FST). For this, first of all find various issues concerning improvement strategies and performance improvement through a questionnaire. OFM has converted these issues into options and then categorize them. The authors have identified 4 improvement strategies as profiles or a Course of actions by using OPM. Pairwise comparison of AHP methodology is used to find the weight of various objectives of manufacturing performance improvement. And finally, the authors have used FST to rank these four improvement strategies by making weighted position matrix and dominance matrix. The present work identified the ranking of TPM strategies for manufacturing performance improvement through multi criteria decision making (MCDM) methodology.

  • Quality Management to facilitate product introduction across borders   Order a copy of this article
    by Promporn Wangwacharakul, Martina Berglund, Ulrika Harlin 
    Abstract: This paper explores how quality management (QM) can be used to mitigate managerial challenges in new product introduction (NPI) across national borders. A longitudinal case study involving one Swedish and one Chinese company was conducted. The data were collected through 35 semi-structured interviews and five workshops with employees and managers of several functions before, during and after NPI in a product development project. Several managerial challenges in the cross-cultural collaboration were revealed. The study demonstrated that lack of understanding of cultural differences negatively affected the NPI process and product quality, but these challenges could be handled by a QM approach. Therefore, this paper proposes QM to help mitigate managerial challenges in cross-cultural NPI. The paper contributes to earlier research on the application of QM and the NPI field by suggesting QM as a means to bridge cultural gaps and facilitate NPI across borders.

    by Nagaraj Kamath, Lewlyn L. R. Rodrigues 
    Abstract: Purpose: Print companies spend a lot in the maintenance related activities, which can be significantly reduced by focusing more on managing operations. The work presented here contributes towards the development of a conceptual framework for operations management in the printing industry. This study also analyses the implications of using the proposed model (Total Production Management) in a printing press. rnMethodology: This study identifies the constructs available in the best industrial practices through literature review. The proposed conceptual model integrates components, thus identified, with other sociotechnical variables. The soundest practices of Total Quality Management (TQM), Total Productive Maintenance (TPM) with human and contextual factors are the core ingredients of the recommended model. rnFindings: The outcome of this study is to develop a conceptual framework for print operation administration that manages a multi-colour offset machine, by incorporating sociotechnical variables in the traditional approaches. rnResearch Limitation: The model elaborated in this paper deals with the print management of multi-colour sheet-fed offset machine only. However, this model has scope to include other pre-press and post press related constructs also. rnPractical implications: Published studies on the combination of sociotechnical variables for print management are insufficient. The conceptual model proposed in this paper would assist the managers to assess, formulate, a suitable strategy for print management, by the blend of sociotechnical variables.rnrnPaper type: Conceptual paper based on literature review.rn

  • Development of lean production system using value stream mapping approach: A case study   Order a copy of this article
    by NAVEEN VIRMANI, Vikram Sharma 
    Abstract: Intense competition in global market is encouraging management to search for new ways to reduce cost and improve profits. Manufacturing firms are realizing that cost reduction through waste elimination can improve their competitive potential. Lean production concepts can be employed for waste elimination. However, managers find it difficult to identify the key areas for waste elimination. The field of lean production has offered VSM as a visualization tool to identify waste elimination opportunities. Using this tool, it is possible to map the current state and accordingly analyze for achieving waste elimination. In order to illustrate this aspect, the case study presented in this paper shows the way the firms can apply VSM for identifying the potential areas for applying this waste elimination technique. The purpose of this research is to examine value stream mapping (VSM) implementation in a gear manufacturing company located in national capital region of India. The case study shows that the production time, inventory and defects can be reduced significantly. Thus, VSM assists the managers to envisage the current level of wastes occurring in an organization and the future means of eliminating them.

  • Unified Process Monitoring Strategy for a Facility Engaged In the Production of Multiple Portfolio of Products   Order a copy of this article
    by Anupam Das, Swarnambuj Suman 
    Abstract: The process monitoring strategies have not kept pace with the development in the production systems. Most of the multivariate statistical process monitoring methods deals with single product portfolio. The current article attempts to devise a unified monitoring strategy for monitoring of multiple products or at least different grades of the same product. A case study from an integrated steel plant producing multiple products has been deliberated to validate the monitoring strategy devised. A comparative evaluation of the unified strategy based on the multigroup variant of principal component analysis (PCA) and the individual strategy based on the conventional PCA was carried out on the basis of three parameters viz. the model fit values, fault detection and the fault diagnosis. In all the three parameters, barring some trifling differences, the unified monitoring strategy seems to replicate the individual strategies well.

  • Integrity of Food Supply Chain: Going beyond Food Safety and Food Quality   Order a copy of this article
    by Siti Norida Wahab, Eric Kaiyue Ling 
    Abstract: As consumers’ trust and confidence in food have been shaken by food incidents that could be intentional (crime) or unintentional (negligence). This paper examines the issue of food integrity in a holistic approach that goes beyond food safety and food quality. The concept of farm-to-fork from supply chain management being adopted to review the extant literature concerning integrity of food supply chain. From the extensive literature review, food safety system such as HACCP is argued to be insufficient in assuring food integrity because it does not prevent deliberate contamination, while traceability and technology are recognised as important communication linkages that provide transparency and evidence on food integrity across the supply chain. This paper has developed the house of food integrity framework to provide novel insights on the food supply chain by illustrating food integrity as a multi-dimensional concept, which incorporates food defence in addition to food safety and food quality.

    Abstract: The standards of maintenance management of buildings at many higher institutions, need improvement. TQM has proven to be effective in the improvement of quality in the maintenance of building facilities, although many higher institutions are still grappling to implement TQM in the maintenance of their buildings. This study examines the perceptions that maintenance workers have about the challenges they face during the implementation of TQM in the maintenance of buildings of institutions’ of higher learning (IHL), assessing whether there are statistical differences based on workers’ affiliated campuses and their positions. A case study approach utilising quantitative data was used in the study where a questionnaire with closed-ended questions was distributed to purposively sampled maintenance workers in an IHL in South Africa. A significant difference was found in the responses provided by workers positions as regards the impact of TQM challenges in their building maintenance activities.

  • Exploring the Applicability of SERVPERF Model in Indian Two-wheeler Industry: A CFA Approach   Order a copy of this article
    by Mohd Adil, Mohd Nasir 
    Abstract: Over the years, after-sales service (ASS) has assumed its importance in the automotive industry. Although, an adequate number of scales and models exist to measure ASS quality, yet extant literature provides evidences in support of two established and well known models/scales viz. SERVQUAL and SERVPERF. But, researchers have raised concerns related to its applicability in a multi-cultural business environment like India. Thus, this study attempts to examine the applicability of original SERVPERF model in Indian two-wheeler industry. Combinations of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) techniques have been used to understand the item structure, dimensionality and psychometric properties of the scale. Results in this study fail to support the item structure of original SERVPERF model as proposed by Cronin and Taylor (1992). We strongly suppose that this variation is context specific and less generic as originally contended. These results suggest that relying service quality assessment on the original SERVPERF items can be misleading in Indian context. As such, context-specific 18-items are therefore needed to assist Indian automobile companies in their service quality improvement programs. If this fit is achieved, the general welfare of consumers vis-

  • A modified control chart for monitoring non normal characteristics   Order a copy of this article
    by Boby John, Subhani S. M 
    Abstract: A process in control and capable of meeting customer requirements can enhance the survival and growth of the business. The systematic use of process improvement methodologies like lean, six sigma, etc., can improve the capability of the process significantly. When the process is highly capable, sometimes it may not make business sense to monitor the process using traditional control charts. It may be better to allow the process mean to vary over a small interval provided the fraction non-conforming is within a pre-specified value. This can be achieved by monitoring the process using the modified control chart. Most of the research on modified control chart discuss the case of normally distributed characteristics. In this paper, the authors extend the modified control chart methodology to monitor non-normal characteristics. The approach is based on Johnson’s system of distributions. The suggested methodology is also demonstrated using two case studies in the paper.
    Keywords: Statistical process control; modified control chart; process capability analysis; non normal characteristics; Johnson's system of distributions.

  • Modelling the barriers of green supply chain practices in Jordanian firms   Order a copy of this article
    by Abbas Al-Refaie, Dina Al-Momani, Rawan Al-tarawneh 
    Abstract: This research investigates ten barriers to adoption of green supply chain management (GSCM) adoption in Jordanian firms using interpretive structural modelling (ISM). Twenty experts from academia and 18 industry were interviewed. Structural self-interaction matrix (SSIM) is developed and then adopted to construct the reachability matrices. The results of ISM model revealed that lack of support from government barrier achieved the highest driving power followed by the barrier cost implications and lack of customer awareness. Moreover, the linkage barriers were the IT implementation problem, resistance to technology advancement adoption, market competition, lack of management commitment, supplier reluctance to change towards GSCM, and lack of sustainability of certificate ISO 14001. These findings suggest that government authorities and top management should resolve barriers at the strategic level by developing effective regulations and incentive policies that enhance customer awareness, supplier commitment to the application of GSCM practices. Further, top managements should ponder on evolving strategies that generate awareness about GSCM adoption. In conclusion, the developed ISM model may provide a valuable guidance to decision makers to understand interdependence of the barriers, determine the required actions to overcome their impacts, and adopt efficient methodologies for effective implementation of GSCM practices in Jordanian firms.

  • Productivity enhancement of assembly line by using Maynard Operation Sequence Technique (MOST) after identification of Lean wastages   Order a copy of this article
    by Raj Kumar, Parveen Kalra, Suman Kant 
    Abstract: The proper utilisation of available resources and appropriate time to complete a task play a crucial role to define the productivity of a line-based manufacturing industry. The high productivity is essential to meet customer demand. If the company fails to meet customer demand, it measures in terms of utilisation of available resources and time required to complete a task. An assembly line includes non-value-added activities and other wastages which lead to lower productivity. Keeping these views in this study, Maynard operation sequence technique (MOST) has been used to reduce cycle time, operation cost and maximise the utilisation of manpower after identification of lean wastages by using Toyota 3M model. The combination of lean manufacturing and MOST has been used as a technique which improves the efficiency of line by 11.23%. The statistical test has been performed by using R programming language to check the significance of applied technique.

    by Mohammed Iqbal Al-Ajlouni, Nawaf Alghusin 
    Abstract: Guided by social-exchange-theory, present study examined transformational leadership (TL) as an antecedent for organisational commitment (OC) and its subsequent influence on job performance (JP). Through using a structured self-administered questionnaire, data were collected surveying (439) non-executive employees operating in (15) banks listed in Amman-Stock-Exchange through non-probability purposive sampling. Structural-equation-modelling using SMART-PLS was utilised and the result reported that TL components achieved 44%, 42.5% and 35.4% of the variance in affective, continuous and normative commitment respectively. Idealised influence did not have any significant effect on any level of OC, whereas intellectual stimulation influenced the three levels of OC. Individualised consideration influenced only affective and continuous commitment, and inspirational motivation influenced only normative and continuous commitment. Moreover, only affective commitment was significant in influencing JP and accounted for 82% of the variance. Following the results, discussion and implication were provided. Also, directions and suggestions for future researches were presented.

  • Overall equipment effectiveness (OEE): a review and development of an integrated improvement framework   Order a copy of this article
    by Chew Keat Cheah, Joshua Prakash, Kok Seng Ong 
    Abstract: The paper reviews the background of OEE and various improvement frameworks and explores their limitations. The review found that there is a lack of improvement frameworks with systematic steps specifically developed for OEE implementation. In addition, it was found that improvement frameworks of different methodologies do not fully capitalise on the use of performance measures as benchmarks and improvement drivers although they provide structured improvement steps/guidelines. These findings show there is a need for a new integrated OEE improvement framework that incorporates the advantages of both OEE and improvement frameworks. By encompassing the core characteristics of OEE and synergising the strengths of improvement frameworks, the new framework will provide OEE practitioners a systematic guidance in carrying out improvement implementation. It will also provide overall directions on how to carry out OEE improvements and allow the practitioners to make better decisions regarding project management.

  • Dynamic Slicing of Aspect-Oriented Software: An UML-based Approach   Order a copy of this article
    by Jagannath Singh, Abhishek Ray 
    Abstract: In this paper, we propose a technique to compute the dynamic slice of UML models for aspect-oriented software. The UML architectural model for aspect-oriented software represents the core components, aspectual components and the relationship between them. Firstly, we construct aspect-oriented model dependence graph (AOMDG) as an intermediate representation of the UML model for aspect-oriented software. AOMDG is a combination of aspect-class dependence graph (ACDG) and aspect-sequence dependence graph (ASDG). ACDG is constructed by using a set of class and set of aspect class diagrams and ASDG is constructed by using a set of sequence and aspect sequence diagrams from the UML architectural model. Then, we propose an algorithm to compute the dynamic slice by traversing AOMDG by marking and unmarking the nodes for a particular scenario during run-time.

    by Suyog B. Rayjadhav, Digvijay A. Mhamane, Vasudev Shinde 
    Abstract: In foundry, sand-moulding takes maximum share of production than other moulding methods. So the foundry requires huge quantity of sand daily. To safeguard environmental issues it is necessary to reuse the sand repeatedly otherwise it also increases disposal cost. In view of increasing demand from environmental and economic aspects, the assessment of sand reclamation systems becomes outmost importance. This study illustrates the various sand reclamation techniques like dry, wet, thermal, cryogenic and microwave reclamation in term of their procedure and assessment. The thermal sand reclamation system is developed comprising of sub units like fluidised bed combustor and fluidised bed sand cooler for 20 kg sand capacity and tested for chemically bonded sand casting. In the present study, developed thermal sand reclamation system is tested and results are compared with different sand reclamation systems. The no-bake-sand can be satisfactorily reclaimed by newly developed thermal sand reclamation technique with appropriate sand quality.

  • Matrix Based Tolerance Analysis for Multi-Component Selective Assembly with Geometric and Dimensional Features using Genetic Algorithm   Order a copy of this article
    by A.K. Jeevanantham, Chaitanya S.V, Rajeshkannan Ananthanarayanan 
    Abstract: Tolerance analysis (TA) is a method of investigating how the geometric and dimensional tolerance (GDT) deviations in each component propagate and affect the functional requirements of the product. Total deviation in an assembly fit can be controlled by selecting the components of the assembly through a purposeful strategy, called selective assembly (SA). In this paper, the matrix model of TA is applied in SA. The surface-based and shape closure analyses are done using the principles of TTRS and MGDE, and the assembly fit is modelled in terms of displacement matrices. The conventional method of dividing the components into groups only by the deviation on dimensional tolerance (DT) alone is replaced by integrated GDT. The effect of rotational displacements in component features on assembly fit is verified. A two-dimensional, worst case, rigid TA in SA is demonstrated. The best combinations of assembly components are obtained through genetic algorithm.

  • Leagile manufacturing paradigm in the production of jet pump   Order a copy of this article
    by K. Balakrishnan, S.R. Devadasan, Thilak VMM, D. Selvi Soundaram 
    Abstract: One of the types of pumps that find high demand from the customers is jet pumps. Today, pump manufacturing companies are required to produce conventionally designed jet pump as well as improved and innovative forms of the same to meet the demand of several customers. This kind of demand can be fulfilled only when leagile manufacturing paradigm is implemented around the production of jet pumps. In order to have a successful implementation of the same, while pursuing the research reported in this paper, a model named as 'pumping for leagility' (PFL) was designed and applied in the case of producing jet pumps in a typical Indian pump manufacturing company. The PFL model has eight steps comprising of 31 activities. By applying PFL model, the nuances of developing leagile manufacturing paradigm in real-time practice was examined and the extent of implementation in the production of jet pump was studied.

    by Mohamed Dia, Shashi Shahi 
    Abstract: Ontario's pulp and paper mills have been facing extreme competitive pressures due to declining markets and low-cost competition from around the world, which have affected their performance and relative technical efficiency. This study uses a non-parametric technique, bootstrap data envelopment analysis, in analysing the operational efficiency of 23 pulp and paper mills in Ontario with sample data collected over a period of 17 years (1999 to 2015). The results indicate low levels of efficiencies due to the management of operations as well as the scale of operations, especially during the economic downturns. In addition, we noticed regional differences in the operational efficiencies of these mills. These results provide comprehensive details to mill managers to reallocated future resources.

  • Modeling Construction labour productivity using Evolutionary Polynomial Regression   Order a copy of this article
    by Zahra Zangenehmadar, Sasan Golnaraghi, Sabah Alkass, Osama Moselhi 
    Abstract: Construction projects are labour-intensive and labour costs are a substantial percentage of total budget. Impaired labour productivity causes an increase in construction project schedule. Labour productivity is one of the most frequently discussed topics in the construction industry, and modelling labour productivity by utilising different techniques has been getting more attention. It is a challenging task as it requires identifying the influencing factors as well as considering the associated interdependencies. This paper investigates the application of evolutionary polynomial regression (EPR) for modelling labour productivity in formwork installation. EPR is a data-driven hybrid modelling technique based on evolutionary computing and has been successfully applied to solving civil engineering problems. Results obtained from the EPR model were compared with the outcomes of three other methods: best subset, stepwise, and general regression neural network (GRNN). Results demonstrate the predictive superiority of the developed EPR model for nonlinear problems based on statistical performance indicators.

  • What is the Role of Expert Intuition in Process Control?   Order a copy of this article
    by Venkat Pulakanam, Mark D. Hanna, Dirk Pons 
    Abstract: Rules of statistical process control (SPC) suggest that processes should not be adjusted by workers without an explicit data-driven management directive. By contrast, in many workplaces, workers are empowered to improve processes and seen as uniquely knowledgeable due to their experience in close proximity to the process. Thus, it absolutely is expected that operators will commit acts of personal agency as they apply their expert intuition. Based on observations of industry practice, we develop a description of expert intuitive process control (EIPC) and a conceptual framework which enables comparison of this approach to SPC and development of postulates regarding the contexts in which each approach is likely to be valued from a practical perspective.

  • Productivity and Quality improvement through DMAIC in SME   Order a copy of this article
    by Janardhan K. Reddy, Soundararajan Krishnasamy 
    Abstract: During the past three decades, researchers have been advocating the application of define-measure-analyse-improve-control (DMAIC) phases of Six Sigma concept to achieve productivity and quality improvement in small and medium enterprises (SMEs). In this context, the research reported in this paper was carried out in a SME by applying DMAIC phases in the production of the castings of a component called balance weight. While executing the DMAIC phases, it was found that green sand moulding process had to be replaced with shell moulding process to avoid the increase in hardness and rejection of castings due to pin hole defect. On implementing this solution, the productivity increased by 50.42 units per hour and the quality level increased from 3.2 sigma to 4.4 sigma. Altogether, it was found that DMAIC can be used in SMEs to achieve productivity and quality improvement so as to acquire competitive strength.

  • Patient satisfaction in hospital emergency services: A perspective from the Portugal.   Order a copy of this article
    by Daniel Ferreira Polonia, Rui Diogo S. Santos, Ana A. C. Dias 
    Abstract: This research paper constructs and validates a conceptual model that identifies the determinants of patient satisfaction with hospital emergency services. The conceptual model is based on an extensive review of the literature on the subject and was validated by 400 interviews in four Portuguese NHS hospital emergency services. Analysis of the data revealed that there are five statistically significant variables that influence satisfaction, whereas satisfaction itself influences the loyalty dimension of the model. Although the sample was diverse and a significant number of patients were interviewed, the study only involved NHS users from one specific region of the country. Nevertheless, it proved possible to use the model to draw several managerial implications and these were analysed for ways in which patient satisfaction with the service could be improved.

  • Defining the weights of the EFQM excellence model criteria for different business sectors   Order a copy of this article
    by Yannis Politis, Evangelos Grigoroudis 
    Abstract: EFQM model is Europes most prestigious award for organisational business excellence given to the best performing organisations in Europe. The aim of this paper is to propose a multicriteria approach to assess the weights of the models criteria based on the specific needs of different business sectors. For this reason a two stage process is proposed. In the first stage, criteria weights are assessed according to the rankings of a set of organisations with different scores on the EFQM excellence model criteria given by business experts from specific sectors or and participants of the quality award. The second stage concerns modifications and additional information or restrictions given by EFQM experts in order to improve the robustness of the preference model estimated from the previous stage. Considering that little can be found in literature concerning a general methodology for the construction of sector specific models, the paper proposes a general approach to adjust the weights of the EFQM model criteria to better fit the specific needs of different business sectors.

  • Extracting Performance Improvement Factors using DEA for a Robust Indian Retail Industry   Order a copy of this article
    Abstract: The Indian retail industry is facing high growth trajectory which is attracting a number of players both domestic and foreign. Given its role in the growth of the Indian economy, a robust retail industry is the need of the hour. An understanding of the efficiency levels of some of the retail players and an identification of the variables that have an impact on the level of efficiency is required to increase and sustain the robustness of the industry. The current study extracts and analyses performance improvement factors that have an impact on the efficiency of organised retail companies of India by analysing data corresponding to 12 variables for six retail companies over a period of seven years. The findings of the study showed that five out of the six Indian retail companies studied faced inefficiency at least during one of the years over the period of seven years under study. The three input variables that the current study suggest need careful consideration by the companies are handling of receivables and inventories (current assets) followed by advertising and power and fuel expenses.

  • A Hesitant Fuzzy Model for Ranking Maintenance Strategies in Small and Medium-Sized Enterprises   Order a copy of this article
    by Mohsen Shafiei Nikabadi, S. Behnam Razavian 
    Abstract: Presently, the topic of ranking is very significant. Most of real world affairs can be solved by using decision-making techniques. Selecting and ranking of maintenance strategies are sometimes complicated. They have no proper structure and also have multi-criteria viewpoint. Hence, proper selecting and ranking could be considered as a multiple-criteria decision-making (MCDM). Consequently, the main goal of this research is selecting the best maintenance strategy by applying factor analysis (FA) technique and also decision-making methods in the hesitant fuzzy domain. In this study firstly by applying literature and experts' viewpoints on maintenance, the variables and their sub-variables were identified. Then, to reduce the number of variables, the factor analysis method was used. Additionally, to calculate the weights of sub-variables De Luca-Termini, which is a normalised hesitant entropy method, was applied. Finally, the strategies were ranked by using hesitant fuzzy VIKOR method. According to this research, the maintenance strategy based on reliable has higher priority in comparison with the others.

  • Risk analysis on the current design of wooden-hulled boats with outrigger using fuzzy FMEA   Order a copy of this article
    by Miriam Bongo, Junny Ann Inot, Claitee Sebios 
    Abstract: In constructing wooden-hulled boats with outrigger, it is imperative to consider design factors that relate to safe operating conditions and sustainability. However, there exists no set of design failure modes in the literature specific to that of wooden-hulled boats with outrigger, thus, making it difficult for stakeholders of the maritime domain to understand fully the risks present in its design and construction. Therefore, this paper applies fuzzy FMEA to assess the risks involved in the design and construction of wooden-hulled boats with outrigger. The proposed methodology is applied in the Philippines, and it is found that high priority should be provided to failure modes pertaining directly to the type of wood used, being the primary component of wooden-hulled boats with outrigger, followed by failure modes specific on the design aspects. With such results, stakeholders are better facilitated on policies to be implemented to achieve an efficiently designed wooden-hulled boat with outrigger.

    by Fikri Dweiri, Samar Ishaq 
    Abstract: Nowadays organisations are finding innovative ways to improve customer satisfaction and increase profitability. This can only be possible if they continuously and effectively improve their products and processes. The purpose of this study is to improve cable insulation process using Lean Six Sigma (LSS). Define, measure, analyse, improve, and control (DMAIC) and failure mode effect and criticality analysis (FMECA) were used to identify one of the critical problems which is break and crack in insulation layer of cables in a case company. The design of experiment (DOE) was used to reduce the occurrence of break and crack in cable insulation. Three main factors (supplier, temperature and pressure) each with two fixed levels were considered. The result showed that supplier and temperature are the only significant main factors at the 95% significance level. All interaction levels were not significant as well as the pressure main factor. The results show that risk priority number (RPN), which is an indicator for productivity improvement, was reduced from 745 to 205. Also the experiment produced fewer defects that lead to improve productivity.

  • Generalized Linear Mixed Logit and Probit Models Applied to US Army and Navy Data   Order a copy of this article
    by Jong-Min Kim, Chuwen Li 
    Abstract: We apply the generalised linear mixed model (GLMM) with logit and probit links to data (Stevens and Anderson-Cook, 2017a, 2017b), which is univariate data with binary response of passing or failing for complex munitions generated to match age and usage rate found in US Department of Defense complex systems (Army and Navy). Instead of the generalised linear model (GLM) used in Stevens and Anderson-Cook (2017b), we propose to apply the adaptive Gaussian hermite quadrature approach (GLMM-AGHQ) (Ha et al., 2017) to predict binary response of passing or failing for the Army and Navy data. We suggest two methods to find the best models for the Army and Navy. The first method is based on statistical inference, the variance of random effect for intercept term for every GLMM given in this paper, and the log-likelihood. The second method focuses on the accuracy of prediction of each model. We compare the GLMMs with the GLMs in terms of inter quartile range (IQR) of the residuals. We find that the models capturing random effects lead to smaller IQR which in the end results in the high accuracy of the models. This accuracy is measured by area under receiver operating characteristic curve (AUC).

  • Production-Inventory Models considering different Carbon Policies: A review   Order a copy of this article
    by Arindam Ghosh, J.K. Jha, S.P. Sarmah 
    Abstract: Mitigating carbon emissions in supply chains has become an important issue in the recent era. Recently, companies are looking for solutions to lessen carbon emissions associated with their supply chains mainly due to carbon policies imposed by different regulatory bodies. Apart from regulations, competitive advantage, ISO certification, customer satisfaction also influence organisations to adopt green practices in their supply chains. Production and inventory are two important aspects of supply chains, and they contribute to a significant amount of cost and emissions. Organisations try to optimise their production and inventory related activities with operational adjustments while operating under different carbon policies. Over the last couple of years, authors have incorporated different carbon policies while optimising supply chains, especially production-inventory policies. This paper presents a review of quantitative models on green production-inventory problems considering different carbon policies and ends with suggestions for future research.

    by Sugandren Naidoo, Roy Ramphal 
    Abstract: The focus in this paper is on integration and combination, as two important concepts in management systems. In this paper, a definition of integration and combination as related to business management is proposed. The lack of resolution can be extrapolated to basic dissimilarities in the competing resource-based perspectives on strategy and the application of strategy typologies based on those standpoints. A comprehensive literature review will be conducted. The authors identify a high-level meta synthesis of integration and combination definitions as related to business management. The findings argue that there are remarkable differences, but also similarities between the analyses of Schumpeter and Anderson’s theories of integration and combination.

    by Mira Thoumy, Marie Hélène Jobin 
    Abstract: The purpose of this study is to characterise the dynamics between the performance management system (PMS) and the quality management system (QMS). We conducted a comparative case study between two university medical centres. We interviewed 41 participants from eight sub-units of analysis. We also conducted seven hours of meeting observations, 16 hours of management observations as well as a review of 46 documents that were submitted to us by the workers. Our results show that there are four types of possible interactions between the PMS and the QMS which are independence, antagonism, communication and collaboration. Moreover, there are three realms of interactions being the realms of structure, identities and practices. We found that the PMS and the QMS interact more in clinical units. The support services do not have well-developed performance and quality management. Also, the workers involved in operations are disconnected from the concept of performance.

  • An internal cooperation as a driver of total quality management   Order a copy of this article
    by Gun Jea Yu, Hojin Jung, Kyoung-min Kwon 
    Abstract: Much evidence has been presented on the critical factors for total quality management (TQM) and its effect on firm performance. Studies aiming to understand TQM have examined the moderators on the relationship between TQM and firm performance. Among these moderators, cooperation among teams and departments has been highlighted but rarely empirically tested. Thus, the paper investigates the conditions under which the effect of TQM is intensified using a sample of 565 firms in Korea. We confirmed that TQM is positively associated with firm performance. In addition, the cooperative internal environment, including the levels of cross-functional team (CFT) and of collaboration between R&D and manufacturing departments (CRM), positively moderates the relationship between TQM and firm performance. This study contributes to the current literature on TQM by considering and testing the moderating effects of collaboration environments.

    Abstract: Short-run control charts are used in situations where limited or no data exist about the process, and conventional statistical process control (SPC) charts are considered ineffective for estimating parameters, such as control limits, because they cannot be established in most cases. This study presents a contemporary review on developing various short-run univariate quality control approaches. Considerable literature is systematically collected on the basis of content analysis. Techniques are differentiated on the basis of repetitive and non-repetitive processes. Subsequently, the principles, data sample collection, performance criteria, robustness and applications of quality control approaches are reviewed.

  • Ripple effect of moral hazard: How do CSR misconducts impact firm performance in the dairy industry?   Order a copy of this article
    by Xiaohua Meng, Yunli Zhu, Meiling Zhong 
    Abstract: In this article we study how collective corporate social responsibility (CSR) misconduct affects the market performance of enterprises in the dairy industry. We do this by revisiting the melamine-tainted milk powder event in China. By comparing pre- and post-event retail data of three different types of infant milk powder manufacturers, as well as by analysing the cumulative abnormal returns (CARs) of those milk powder companies listed on stock markets, based on an event study approach, the ripple effect of China's melamine incident as an exogenous shock was investigated. The results show that industrial CSR misconduct has a suppression effect on the enterprises involved, overlapping suppression and spillover effects on domestic enterprises that were not involved, as well as spillover effects for foreign peers. Lessons from the melamine contamination incident and its policy implications should be valuable in promoting the CSR level and sustainability of other similar fast-growing industries in developing countries.

    by Hayat Lionboui, Fouad Elame, Abdelghani Boudhar, Rachid Hadria, Brahim El Boukari, Tarik Benabdelouahab 
    Abstract: In order to improve socio-economic conditions in rural areas, the purpose of this study is to develop models for estimating wheat yield based on the use of agricultural inputs. The emphasis is not only on increasing production, but on economically efficient production that optimises productive resources. Thereby, a cost efficiency analysis for wheat producers was conducted based on a sample of 111 farmers in the Tadla Plain in central Morocco. To achieve this objective, two models devoted to wheat yield estimation in terms of costs and quantities of agricultural inputs were developed, based on stepwise regression approach. Furthermore, data envelopment analysis (DEA) method was used to analyse the cost efficiency of farms. Overall, this work separates the excess costs related to technical efficiency and economies of scale to cost efficiency in order to understand the type of actions that farmers can take to reduce production costs and ensure their resilience.

  • Firefly Enabled Agility Assessment in Manufacturing Systems   Order a copy of this article
    Abstract: The manufacturing processes have now evolved from dinosaur type of enterprise to lizard type known as agile manufacturing. Agility can be enhanced with some trivial change in firm's processes. In this study, an effort has been made to obtain the agility index of two different firms with their currently implemented agile enablers'. The two industries were identified based on the demand pattern, i.e., seasonal and volatile demand. The methodology of AHP is used to obtain effectiveness of the agile enablers’. These effectiveness values are given as input to the FA to obtain the agility index in terms of 'response time’ between market and industry. Based on the results, the firms' can focus on the enabler with least response time to improve business performance through appropriate strategies. The response time of fashion firm is less than that of core-manufacturing firm. Hence fashion firms are more agile than core firms.

  • Evaluating the influence of individuals’ personality characteristics on the preference of choosing and buying goods with an emphasis on the moderating role of mental involvement   Order a copy of this article
    by Seyed Fathollah Amiri Aghdaie, Hamidreza Talaie, Paria Soltanpoor 
    Abstract: The present research evaluates the influence of individuals' personality characteristics on the preference of choosing and buying goods with an emphasis on the moderating role of mental involvement. The statistical population of this study is the customers of the Dillards chain store in Austin in the state of Texas in USA. Using the Schumacher and Lumax method, 256 people were selected as a statistical sample and a questionnaire was used to collect data. The collected data were analysed using SPSS and AMOS Software Version 24 with structural equation model. Based on the results, we can state that, among the personality characteristic of these customers, openness to experience, emotional stability, agreeableness and conscientiousness are the most effective ones to create mental involvement that indirectly lead to purchasing decision. Extraversion, agreeableness and conscientiousness also directly lead to consumer preferences.

  • Co-deployment of quality standards: A systematic literature review   Order a copy of this article
    by DAHAR Hind, Ounsa Roudies 
    Abstract: Within a competitive environment marked by strong technological evolution, organisations have to be compliant at the same time with several repositories, norms or standards relating to quality of their processes continuous improvement. Diversity of standards can lead to different issues such as heterogeneity, redundancy and also increasing costs for their implementation in terms of time, resource mobilisation and budget. To solve these problems, the idea is to establish an alignment approach that guarantees the high level of quality wished by using several standards simultaneously. This article is a systematic review of literature specific to methods of alignment of norms and quality standards. We raise the problems caused by lack of alignment, and review existing approaches and their results.

    by Bjørn Willy Åmo, Lars Kolvereid 
    Abstract: The purpose of this study is to investigate the relationship between three central dimensions of quality in small accounting firms and firm performance. The three dimensions of quality investigated are: human resource (HR) quality, information technology (IT) quality and service quality. Firm performance is measured in two different ways: perceived performance and return on sales (ROS). We tested the hypotheses in a sample of 506 small Norwegian accounting firms. The results indicate that service quality relate positively to perceived performance and ROS. Human resource quality is positively related to perceived performance, but not ROS. IT quality is not related to perceived performance and negatively related to ROS. This study contributes to the literature by providing empirical evidence for a positive relationship between service quality and firm financial performance and has important implications for accounting firms and their clients.

  • Evaluation of Quality cost in a multinational company located in Tangier, Morocco   Order a copy of this article
    by Mohamed B.E.N. ALI, Dina BAGHDADI MAZINI, Said Barijal, Insaf GHAILANI 
    Abstract: This study aims to evaluate the cost of obtaining quality (CoQ) of a multinational company in Tangier specialised in wiring. It also tries to identify the measures that can reduce the cost of non-quality and improve productivity time and there by improve competitiveness. According to our study, the CoQ represents 14.5% of the turnover including 10.4% of non-quality (internal and external failures). An analytical study was carried out concerning the quantification of all the components constituting the internal anomaly. It showed that machine stops have a significant effect on the increase of internal failures. To detect the main causes of non-performance, DMAIC, SMED and AMDEC approaches were used to decrease non-productivity time. This allowed the company to gain 41.3 days/year relative to each machine, which contributed to increase productive time and to generate an annual financial profit of 361370.24 euros (as a reduction of the non-quality cost of 6.36%).

  • Diagnosis Framework for Quality Management System in Blood Banks: a Brazilian Case Study.   Order a copy of this article
    by Vinícius Lemos, Vitor Bernardo, Ana Honda, Mateus Gerolamo, Cesar J.C. M. Costa, Andrew M. Bacelar, Leonardo P. Ruli, Matheus S. Dall\\'Agnol 
    Abstract: Healthcare organisations face many challenges regarding market competitiveness, client expectations and regulatory demands. Quality management systems (QMS) have emerged as effective support tools for managers and the demand for ISO certification has increased. However, the process of diagnosing the QMS before certification is often complex, time-consuming and expensive. This article proposes a framework for QMS evaluation consisting of a diagnostic tool for blood banks. The methodology combines a set of international quality standards, change management principles and process mapping tools. It can be applied through internal audits, thus it is useful for organisations that seek relevant certification to define the next steps to be taken for improvement. A case study in a Brazilian blood bank illustrates the results of the framework. The pilot of the diagnostic tool was successful in identifying gaps that required further development by presenting maturity levels for each requirement of the international standards.

  • Value stream mapping implementation: An Operational View   Order a copy of this article
    by Changiz Valmohammadi 
    Abstract: Value stream mapping (VSM) is an important tool which identifies and reduces errors and losses, and enhance product quality which could lead to empowered production unit and the reduction of production cost in a lean production (LP) environment. The main purpose of this study is to investigate the operational principles of lean approach using proposed processes for VSM implementation, and through extracting the required information of VSM, and using related methods and techniques. Based on a case study in a manufacturing firm and using VSM technique, the operational processes and the specific steps which cause loss in production process were identified and removed using Kaizen approach. The obtained results show increased value added in final product, improved production process, reduced lead time and improved value creating time, which are shown in the future VSM. Using principles of VSM and following a Kaizen approach, helped the authors to identify loss points, and make right decisions to choose the best methods and lean tools for improvement. The surveyed company can avail the proposed method and future VSM towards analysing its current processes and making the necessary changes toward decreasing production cost and enhanced product quality which could lead to increased customer satisfaction.
