TL;DR: In this article, the authors investigated the impact of five essential lean methods, i.e. JIT, autonomation, kaizen, total productive maintenance (TPM) and value stream mapping (VSM), on contemporary measures of operational performance, and found that JIT and automation have the strongest significance on operational performance while Kaizen, TPM and VSM seem to have a lesser or even negative effect on it.
Abstract: Evidence suggests that lean methods and tools have helped manufacturing organisations to improve their operations and processes. However, the real effect of these methods and tools on contemporary measures of operational performance, i.e. cost, speed, dependability, quality and flexibility, is still unclear. This paper investigates the impact of five essential lean methods, i.e. JIT, autonomation, kaizen, total productive maintenance (TPM) and value stream mapping (VSM), on these measures. A linear regression analysis modelled the correlation and impact of these lean practices on the operational performance of 140 manufacturing organisations around the world. In addition, structural equation modelling (SME) was used to cross verify the findings of the regression and correlation analyses. The results indicate that JIT and automation have the strongest significance on operational performance while kaizen, TPM and VSM seem to have a lesser, or even negative, effect on it. This paper provides further evidence...

TL;DR: In this article, the state of adoption of green supply chain management practices by Indian firms was still in its infancy, the awareness of environmental sustainability was quite low among consumers, and the regulatory framework was also lacking in terms of promoting environmental sustainability.
Abstract: Research on green supply chain management (GSCM) or sustainable supply chain management (SSCM) has attracted increased attention in recent years. Although GSCM/SSCM has been studied for developed and developing countries, there has been little information about the adoption of GSCM/SSCM practices in India. This article presents one of the earliest surveys on GSCM practices in Indian manufacturing firms. The items for the survey were developed based on the extant literature and feedback from corporates. Some of the major findings of the survey are as follows. We found that the state of adoption of GSCM practices by Indian firms was still in its infancy, the awareness of environmental sustainability was quite low among consumers, and the regulatory framework was also lacking in terms of promoting environmental sustainability. Results of data analysis showed that supplier collaboration for environmental sustainability had a positive impact on environmentally sustainable product design and logistics, which in...

TL;DR: In this paper, the authors adopt the opposing theoretical views of legitimacy - institutional and strategic - in evaluating firm performance and top management commitment as antecedents to green procurement and green supplier development.
Abstract: This study adopts the opposing theoretical views of legitimacy - institutional and strategic - in evaluating firm performance and top management commitment as antecedents to green procurement and green supplier development. Additionally, the impact of green procurement and green supplier development on supplier performance is analysed. Using a sample of western European companies, we develop a structural equation model to test our hypotheses. We find that the buying firm's market performance positively relates to the adoption of green procurement. While financial performance has no effect on green procurement, top management commitment is found to be an important driver of both green procurement and green supplier development. Moreover, the relationship between green procurement and supplier performance is fully mediated by green supplier development. The paper addresses a research gap concerning firm-level antecedents for green procurement and green supplier development showing that both practices may impact supplier performance. Furthermore, it is shown that legitimacy concerns drive basic green procurement, whereas top management is decisive for advanced practices, such as green supplier development. © 2013 Taylor & Francis.

TL;DR: In this paper, a retailer's joint decisions on inventory replenishment and carbon emission reduction investment under three carbon emission regulation policies are analyzed, including carbon cap, tax and cap-and-trade policies.
Abstract: Carbon emission regulation policies have emerged as mechanisms to control firms’ carbon emissions. To meet regulatory requirements, firms can make changes in their production planning decisions or invest in green technologies. In this study, we analyse a retailer’s joint decisions on inventory replenishment and carbon emission reduction investment under three carbon emission regulation policies. Particularly, we extend the economic order quantity model to consider carbon emissions reduction investment availability under carbon cap, tax and cap-and-trade policies. We analytically show that carbon emission reduction investment opportunities, additional to reducing emissions as per regulations, further reduce carbon emissions while reducing costs. We also provide an analytical comparison between various investment opportunities and compare different carbon emission regulation policies in terms of costs and emissions. We document the results of a numerical study to further illustrate the effects of investment...

TL;DR: In this paper, a theoretical conceptual model was developed based on a review of the literature, followed by a exploratory research questions applied to manufacturing companies that use the lean, Six Sigma or LSS manufacturing models in southern Brazil.
Abstract: There is a growing need for operations management models that contribute to the continuous improvement of company processes, among them we highlight lean manufacturing, Six Sigma and, more recently, Lean Six Sigma (LSS). This article aims (1) to identify and analyse the differences and complementarities in the production decision areas for each one of the three models; (2) to identify the competitive priorities that lead to the best performance as a result of policies followed in the decision areas as a result of the adopted model. First, a theoretical conceptual model was developed based on a review of the literature, followed by a exploratory research questions applied to manufacturing companies that use the lean, Six Sigma or LSS manufacturing models in southern Brazil. The main results show that there are differences in the models in relation to the importance of the decision areas and the performance achieved in the competitive priorities. Individually, lean manufacturing, Six Sigma and LSS have vary...

TL;DR: In this paper, the authors have shown that Indian manufacturing industries have started adopting green concepts in their supply chain management giving special attention to environmental issues based on pressures from different directions, e.g., customer pressure, government regulations etc.
Abstract: Due to growing awareness about environment protection, firms are forced to implement environmental practices to enhance their green image. In recent times, academicians and practitioners have shown interest in green marketing and green supply chain management (GSCM). Fields of green branding and sustainability have seen special interest from different business disciplines including information management, marketing, supply chain management, etc. Due to economical and ecological impact, there is a growing concern for the environment and related critical issues. Pressure on the environment is dynamic and diverse, and demands new levels of accountability, financial commitment and supply chain capabilities. Indian manufacturing industries have started adopting green concepts in their supply chain management giving special attention to environmental issues based on pressures from different directions, e.g. customer pressure, government regulations etc. Yet, industries struggle hard to identify essential pressu...

TL;DR: In this article, a complex adaptive supply network (CASN) lens is used to frame what existing literature has uncovered regarding disaster relief efforts, showing how important differences in the flows of resource, money, and information are identified.
Abstract: The frequency and intensity of disasters continue to increase. Following large-scale and catastrophic disasters, local organisations integrate with other responding organisations to form hastily disaster relief supply chain networks. Such supply networks are infrequently activated in a single location, generate unparalleled uncertainty, change quickly, and are driven by the urgency of saving lives and restoring livelihoods. Unfortunately, even where sound supply chain management practices are used, supply networks have encountered diverse levels of resilience and adequate disaster relief performance has remained elusive. In this paper, several unique characteristics that disaster relief efforts exhibit are examined as compared with demand-driven, steady-state supply chains. Important differences in the flows of resource, money, and information are identified. A complex adaptive supply network (CASN) lens is used to frame what existing literature has uncovered regarding disaster relief efforts, showing how...

TL;DR: In this article, a comprehensive tool called the leanness assessment tool (LAT) is developed, using both quantitative (directly measurable and objective) and qualitative (perceptions of individuals) approaches to assess lean implementation.
Abstract: Lean principles have long been recognised as a competitive advantage. Although there are several measures for various aspects of lean production in the literature, there is no comprehensive measure for overall lean implementation in business firms. An appropriate measurement tool is needed to assess the effectiveness and efficiency of the lean implementation throughout the entire organisation. Based on lean research, a comprehensive tool called the leanness assessment tool (LAT) is developed, using both quantitative (directly measurable and objective) and qualitative (perceptions of individuals) approaches to assess lean implementation. The LAT measures leanness using eight quantitative performance dimensions: time effectiveness, quality, process, cost, human resources, delivery, customer and inventory. The LAT also uses five qualitative performance dimensions: quality, process, customer, human resources and delivery, with 51 evaluation items. The fuzzy method allows managers to identify improvement needs...

TL;DR: In this paper, a framework of supply chain design is proposed that comprehends three key levels of factors critical in understanding the design of a supply chain: influencers, design decisions and building blocks.
Abstract: Truly effective supply chain management is planned and purposive. A value-driven supply chain that is coupled to the strategic priorities of the firm is the result of deliberate management action and strategic corporate investments aimed to procure, develop and configure the appropriate resources, processes and metrics that define that firm’s supply chain. A framework of supply chain design is proposed that comprehends three key levels of factors critical in understanding supply chain design: influencers, design decisions and building blocks. Influencers are higher-level considerations such as the business and political environment, the business model employed, the firm’s desired outcomes and the supply chain life cycle. Design decisions include the social, behavioural and physical/structural design elements that define a supply chain. Building blocks include the inventory, transportation, capacity and technology decisions that are used to implement the supply chain. Supply chain design needs to comprehen...

TL;DR: In this paper, the authors defined the architecture of SCA as the integration of three sets of resources, data management resources (DMR), IT-enabled planning resources and performance management resources.
Abstract: This study seeks to better understand the role of supply chain analytics (SCA) on supply chain planning satisfaction and operational performance. We define the architecture of SCA as the integration of three sets of resources, data management resources (DMR), IT-enabled planning resources and performance management resources (PMR), from the perspective of a resource-based view. Based on the data collected from 537 manufacturing plants, we test hypotheses exploring the relationships among these resources, supply chain planning satisfaction, and operational performance. Our analysis supports that DMR should be considered a key building block of manufacturers’ business analytics initiatives for supply chains. The value of data is transmitted to outcome values through increasing supply chain planning and performance capabilities. Additionally, the deployment of advanced IT-enabled planning resources occurs after acquisition of DMR. Manufacturers with sophisticated planning technologies are likely to take adva...
TL;DR: In this article, the authors proposed a three-level framework and a holistic set of measurement instruments to help researchers and managers measure each critical dimension in a timely and comprehensive manner in a focus group consisting of six quality managers validated these results.
Abstract: In times of globalisation and international trade, the concept of total quality management (TQM) as a strategy to enhance organisational performance is growing in importance. To exploit the benefits provided by TQM, organisations must manage the complex implementation process successfully. Therefore, organisations need to measure critical success factors (CSFs) when introducing TQM. However, previous research has developed a plethora of measurement instruments and researchers do not agree on certain factors or on one single measurement instrument. A systematic literature review is conducted to structure and clarify the scattered research field. The analysis of 145 studies reveals that CSFs can be classified into 11 distinct dimensions. The article proposes a three-level framework and a holistic set of measurement instruments to help researchers and managers measure each critical dimension in a timely and comprehensive manner. A focus group consisting of six quality managers validated these results. The st...
TL;DR: In this article, the authors empirically tested the role of organisational resilience capacity-related variables on firm product innovativeness and performance, and found that competence orientation and original/unscripted agility are positively related to firm product innovation.
Abstract: The term resilience has attracted the attention of many researchers from a variety of disciplines; however, an organisation’s resilience capacity has rarely been addressed in the new product development literature. In this study, we empirically tested the role of organisational resilience capacity-related variables on firm product innovativeness and performance. By studying 112 firms, we found that competence orientation and original/unscripted agility are positively related to firm product innovativeness. We also found that with increasing levels of technological turbulence, original/unscripted agility, practical habits and behavioural preparedness are positively associated with product innovativeness, whereas competency orientation is negatively related. Furthermore, we found that product innovativeness mediates the relationship between resilience capacity and firm performance.
TL;DR: In this article, a new assessment framework for assessing sustainability from lowest levels, dimensions up to sustainable development level according to Micro-Level is presented. But the main objectives addressed in this paper is how to model the required components and how to introduce a new assess framework for assess sustainability.
Abstract: Sustainable development (SD) will be the driving force to Twenty-first Century as automation was to the Twentieth Century and stream was to Nineteenth Century. There are two levels of sustainability: Macro-Level (country, cities) and Micro-Level (manufacturing enterprises and its town and regional areas). In this paper, Micro-Level of sustainability will be discussed. The major challenge of manufacturing enterprises is modelling and assessing the sustainable development performance. Introducing indexes for sustainable development assessment in manufacturing enterprises is important not only to enable them to quantitatively estimate SD, but also to determine the requirements of components for these enterprises to survive. The main objectives addressed in this paper is how to model the required components and how to introduce a new assessment framework for assessing sustainability from lowest levels, dimensions up to sustainable development level according to Micro-Level. The three pillars of sustainability...
TL;DR: In this paper, a theoretical model of the impact of two organisational characteristics, namely organisational learning and an organic structure (with three dimensions, which are decentralization of decision-making, low formalization and a flat structure), on workforce agility was developed and empirically tested.
Abstract: Studies on agility in the workplace have focused excessively on technical factors, and little attention has been given to the workforce. Most studies on workforce agility are conceptual and have a notable absence of quantitative modelling and analysis. In the study, a theoretical model of the impact of two organisational characteristics, namely organisational learning and an organic structure (with three dimensions, which are decentralisation of decision-making, low formalisation and a flat structure), on workforce agility was developed and empirically tested. Several small- and medium-sized enterprises in Iran were investigated. The structural equation modelling showed that organisational learning and only the decentralisation of decision-making and a flat structure were positively and significantly correlated with workforce agility. The impact of the dimensions of an organic structure on organisational learning was also considered. Based on the results, we proposed a process model on workforce agility.
TL;DR: In this paper, the effects of fairness-concerned status-seeking behaviors on optimal decisions as well as channel efficiency are further analyzed for a dyadic supply chain in which both the supplier and the retailer have the preference of statusseeking with fairness concerns, and it is shown that the channel efficiency will decrease because of such behavioral preference.
Abstract: The paper investigates newsvendor problem for a dyadic supply chain in which both the supplier and the retailer have the preference of status-seeking with fairness concerns. Nash bargaining solution is introduced as the fairness reference point and equilibrium results are derived. The effects of fairness-concerned status-seeking behaviors on optimal decisions as well as channel efficiency are further analyzed. It is shown that the channel efficiency will decrease because of such behavioral preference. The retailer’s share will be larger when the supplier concerns fairness less, and the supplier’s sensitivity to fairness plays a relatively more important role for the channel efficiency. Additionally, another interesting managerial insight is concluded that fairness concerns will not change the status of channel coordination in certain conditions. More specifically, those contracts able (unable) to coordinate fairness-neutral supply chain, based on affine transformations with scale factors within certain ra...
TL;DR: In this article, a review of the state-of-the-art research on product configuration is presented, covering the major issues, definitions and concepts in product configuration along with corresponding studies, such as configuration ontology, system design and development, and configuration solving.
Abstract: Being able to provide companies with a number of advantages in delivering customised products, product configuration has received increasing attention from the academia and lasting interests from industries in the past several decades. While several surveys and reviews have been reported shedding light on specific issues in product configuration, a general overview is missing. By systematically presenting important concepts, definitions and issues underlying product configuration, such a review is of paramount importance to develop practical solutions, which ultimately contributes to efficient design, development and implementation of product configurators in practice. This study, thus, tries to fill this gap by reviewing the state-of-the-art research on product configuration. It touches on the major issues, definitions and concepts in product configuration along with the corresponding studies, such as configuration ontology, system design and development, and configuration solving. Based on the review, f...
TL;DR: In this paper, a heuristic has been proposed to assign the disassembly tasks/parts to the work stations under its precedence constraints, which incorporates Fuzzy analytic hierarchy process (Fuzzy AHP) and PROMETHEE method for the selection of tasks for assignment to disassembly line.
Abstract: Nowadays, new products have been introduced in the market at an ever increasing pace due to rapid technology advancement. Consequently, products are becoming outdated and discarded faster than ever before. Since the demand for new solutions to economically deal with such outdated products begun to rise, the disassembly line has emerged as a viable solution to this problem. The disassembly line has been considered as a viable choice for automated disassembly of returned products. The problem of sequence generation in disassembly is complex due to its NP-Hard nature and therefore the heuristically solutions are most preferable for these types of problems. In this paper, a heuristic has been proposed to assign the disassembly tasks/parts to the work stations under its precedence constraints. It incorporates Fuzzy analytic hierarchy process (Fuzzy AHP) and PROMETHEE method for the selection of tasks for assignment to the disassembly line. The Fuzzy AHP has been used to find the relative importance of each cri...
TL;DR: In this paper, the authors suggest an interconnected relationship among TQM, organisational learning capability (OLC), business innovativeness, and a firm's financial performance and propose that OLC and business innovateativeness mediate the relationship between total quality management and financial performance.
Abstract: The concept of total quality management (TQM) has attracted many researchers from a variety of disciplines. In particular, the literature has addressed the impact of TQM on a firm’s operations and performance. However, disparate perspectives on the relationship between TQM and a firm’s financial performance have emerged. In this paper, we suggest an interconnected relationship among TQM, organisational learning capability (OLC), business innovativeness, and a firm’s financial performance and propose that OLC and business innovativeness mediate the relationship between TQM and a firm’s financial performance. By studying 193 firms in Turkey, we found that: (1) TQM affects OLC and a firm’s business innovativeness, (2) OLC influences a firm’s business innovativeness and (3) a firm’s business innovativeness affects its financial performance. Also, we found that OLC and business innovativeness in a firm mediate the relationship between TQM and the firm’s financial performance.
TL;DR: In this paper, the authors proposed a flexible job shop scheduling method to minimize the total production cost of the flexible job-shop scheduling problem, which considers both time-dependent and machine-dependent electricity costs.
Abstract: Many countries are actively trying to cope with recent effects of climate change and the energy crisis. At the same time, efficient energy use and the reduction of greenhouse gas emissions are very important, not only to reduce energy costs but also to contribute to an environment-friendly, sustainable lifestyle. Currently, manufacturing industries in some countries pay stratified electricity rates that depend on the time of the day (i.e. peak load, mid-load and off-peak load). Hence, the production scheduling process, which considers time-dependent and machine-dependent electricity costs, enables these industries to minimise energy expenses. Additionally, the emerging Smart Grid is supposed to require industries to pay real-time hourly electricity costs. More energy-efficient, intelligent production scheduling is thus a major goal. This paper deals with minimising the total production cost of the flexible job-shop scheduling problem. Our method allows each decision-maker in the manufacturing industry to ...
TL;DR: In this paper, the authors consider a location allocation problem in a closed-loop supply chain with two extensions: demand and prices of new and return products are regarded as non-deterministic parameters and the objective function is developed from expected profit to three types of mean-risk ones.
Abstract: This paper considers a location-allocation problem in a closed-loop supply chain (CLSC) with two extensions: first, demand and prices of new and return products are regarded as non-deterministic parameters and second, the objective function is developed from expected profit to three types of mean-risk ones. Indeed, design and planning an integrated CLSC in real-world volatile markets is an important and necessary issue. Further, risk-neutral approaches, which are considered expected values, are not efficient for such uncertain conditions. Hence, this paper, copes with the design and planning problem of a CLSC in a two-stage stochastic structure. Besides, risk criteria are considered through using three types of popular and well-behaved risk measures: mean absolute deviation, value at risk and conditional value at risk (CVaR). Consequently, three types of mean-risk models are developed as objective functions and decision-making procedures are undertaken based on the expected values and risk adversity crite...
TL;DR: In this paper, the authors examined the impact of managerial ties and trust on supply chain information sharing and supplier opportunism and found that through trust managerial ties can significantly influence the extent of information sharing, but not on the quality of the information shared.
Abstract: Managerial ties and trust are important factors in facilitating collaboration and reducing opportunistic behaviour. There is, however, a lack of empirical evidence on how these relational factors influence the sharing of information among supply chain partners. For example, do stronger managerial ties help to improve supply chain information sharing (SCIS) and reduce supplier opportunism? To what extent SCIS is influenced by managerial ties and trust? How do managerial ties interact with trust in influencing SCIS? Using data from 272 Chinese manufacturers, this paper examines the impact of managerial ties and trust on SCIS and supplier opportunism. The results show that, through trust managerial ties can significantly influence the extent of information sharing and the quality of the information shared. Managerial ties also have a direct impact on the extent of information sharing, but not on the quality of the information shared. The main implication for management practice is that the quality of the inf...
TL;DR: In this article, a dual-channel supply chain with one risk neutral manufacturer and one risk-averse retailer where there is only one perishable product with price-dependent stochastic demand is investigated.
Abstract: This paper investigates a dual-channel supply chain with one risk-neutral manufacturer and one risk-averse retailer where there is only one perishable product with price-dependent stochastic demand. We choose Conditional Value-at-Risk criterion to measure the retailer’s risk-averse level, and assume that the manufacturer’s direct sales channel and the retailer’s traditional channel adopt a consistent pricing strategy. The model explores a Nash bargaining problem where the manufacturer and the retailer negotiate with each other on the wholesale price, the retail price and the order quantity when they have equal bargaining power. It is found that when demand uncertainty follows a uniform distribution, a Nash bargaining equilibrium exists and the retail price will decrease as the retailer becomes more risk averse. However, when the risk-averse indicator increases, the manufacturer’s profit on his direct channel will decrease, increase or first increase and then decrease, depending on the values of the relate...
TL;DR: In this paper, the authors model the asynchronous shipment and creation of containers within an interconnected network of services, find the best path routing for each container and minimise the use of transportations means.
Abstract: Logistic networks intensely use means of transportation and storage facilities to deliver goods. However, these logistic networks are still poorly interconnected and this fragmentation is responsible for a lack of consolidation and thus efficiency. To cope with the seeming contradiction of just-in-time deliveries and challenging emissions targets, a major improvement in supply networks is sought here. This new organisation is based on the universal interconnection of logistics services, namely a Physical Internet where goods travel in modular containers for the sake of interconnection in open networks. If from a logical point of view, merging container flows should improve efficiency, no demonstration of its potential has been carried out prior to the here reported research. To reach this potentiality assessment goal, we model the asynchronous shipment and creation of containers within an interconnected network of services, find the best path routing for each container and minimise the use of transportations means. To carry out the demonstration and assess the associated stakes, we use a set of actual flows from the fast-moving consumer goods sector in France. Various transportation protocols and scenarios are tested, revealing encouraging results for efficiency indicators such as CO2 emissions, cost, lead time, delivery travel time, and so forth. As this is a first work in the field of flows transportation, the simulation model and experiment exposes many further research avenues.
TL;DR: In this paper, a framework for supply chain risk management (SCRM) is proposed and is applied using the data collected from the data coll and the data available in the data collection.
Abstract: Recent years have witnessed a focus on managing risks in supply chains On the one hand, there are many cases where events like natural disasters, strikes and terrorism have significantly influenced the performance of organisational supply chains and in turn their competitiveness And on the other hand, operational activities and strategic decisions of the firms (concerning, for eg supply, procurement, production, delivery, commercialisation, demand management, planning, etc) can be different than expected and so create uncertainties Uncertainties, whether they are external or internal, impact organisations leading to increased supply chain risk Realising the potential implications of these situations on supply chain competitiveness, an attempt has been made to define risks and their sources and to identify the management that can help reduce the negative impact of risks on supply chains In this paper, a framework for supply chain risk management (SCRM) is proposed and is applied using the data coll
TL;DR: In this paper, a joint economic lot size (JELS) model for coordinated inventory replenishment decisions under the vendor-managed inventory (VMI) with consignment stock (CS) agreement and an emission-trading scheme is presented.
Abstract: This paper presents a joint economic lot size (JELS) model for coordinated inventory replenishment decisions under the vendor-managed inventory (VMI) with consignment stock (CS) agreement and an emission-trading scheme. The paper assumes a single product that flows along a two-level supply chain system, with a single vendor and a single buyer. The total cost of the system is the performance measure, which is the sum of the vendor’s and the buyer’s total costs. The total cost includes the set-up and order costs, inventory holding costs, greenhouse gases (GHG) emissions tax and penalty costs. A mathematical model is proposed to determine: (1) the vendor’s production lot size quantity; (2) the number of shipments sent by the vendor to the buyer in a cycle; and (3) the production rate that minimises the total cost of the supply chain. Some numerical examples are carried out, as well as comparisons with the traditional JELS model for a classic two-level supply chain. Results show that the performance of the sy...
TL;DR: In this paper, the authors present a review of optimization models for tactical production planning and identify streams and future research directions in this field based on the different classification criteria proposed by the authors.
Abstract: This study presents a review of optimization models for tactical production planning. The objective of this research is to identify streams and future research directions in this field based on the different classification criteria proposed. The major findings indicate that: (1) the most popular production-planning area is master production scheduling with a big-bucket time-type period; (2) most of the considered limited resources correspond to productive resources and, to a lesser extent, to inventory capacities; (3) the consideration of backlogs, set-up times, parallel machines, overtime capacities and network-type multisite configuration stand out in terms of extensions; (4) the most widely used modelling approach is linear/integer/mixed integer linear programming solved with exact algorithms, such as branch-and-bound, in commercial MIP solvers; (5) CPLEX, C and its variants and Lindo/Lingo are the most popular development tools among solvers, programming languages and modelling languages, respectively...
TL;DR: In this paper, a multi-product, multi-facility capacitated closed-loop supply chain framework is proposed in an uncertain environment including reuse, refurbish, recycle and disposal of parts.
Abstract: Owing to the revolution in sustainable and green manufacturing the production planning and network design of closed loop supply chain concept has got the attention of researchers and managers. In this paper, a multi-product, multi-facility capacitated closed-loop supply chain framework is proposed in an uncertain environment including reuse, refurbish, recycle and disposal of parts. The uncertainty related to demand, fraction of parts recovered for different product recovery processes, product acquisition cost, purchasing cost, transportation cost, processing, and set-up cost is handled with fuzzy numbers. A fuzzy mixed integer linear programming model is proposed to decide optimally the location and allocation of parts at each facility and number of parts to be purchased from external suppliers in order to maximise the profit of organisation. The proposed solution methodology is able to generate a balanced solution between the feasibility degree and degree of satisfaction of the decision maker. The propo...
TL;DR: In this article, the authors present a method for assessing the impact of HRM practices and organizational learning factors in a company under lean implementation, using a case study from the automotive parts manufacturing sector.
Abstract: The implementation of lean production systems is deemed essential for companies that wish to obtain high levels of competitiveness. There are several examples in the literature discussing the adoption of lean roadmaps; however, since such maps emphasise technical factors of lean change, the organisational learning (OL) process and human resources management (HRM) practices tend to be neglected. This article presents a method for assessing the impact of HRM practices and OL factors in a company under lean implementation. The method incorporates concepts of HRM and OL into lean implementation roadmaps, enabling a maturity analysis regarding dimensions of OL at different contextualisation levels, and allowing the proposition of improvements in HRM practices. The proposed method is illustrated in a case study from the automotive parts manufacturing sector.
TL;DR: In this article, the authors identify the required elements to evaluate sustainability of manufacturing processes and develop the needed measurement science and methodology to evaluate sustainable of fundamental manufacturing processes to ensure reliable and consistent comparisons.
Abstract: Manufacturing industries lack the measurement science and the needed information base to measure and effectively compare environmental performances of manufacturing processes, across resources and associated services with respect to sustainability. The current use of ad hoc methods and tools to assess and describe sustainability of manufactured products does not necessarily account for manufacturing processes explicitly, and hence results in inaccurate and ambiguous comparisons. Such comparisons do not proactively contribute to sustainability improvement. Further, we identified that there are no formal methods for acquiring and exchanging information that help establish a consolidated sustainability information base. Our ultimate goal is to develop the needed measurement science and methodology to evaluate sustainability of fundamental manufacturing processes to ensure reliable and consistent comparisons. As a precursor, based on a literature study, this paper identifies the required elements to evaluate ...
