Previous studies have found general differences between non‐lean and lean production systems, but none of them have identified the major factors in supporting operations such as maintenance which are important in shifting the production from a non‐lean to a lean system. The purpose of this paper is to determine the major factors and parameters of maintenance operations that are most effective in enhancing production to a lean system.

A questionnaire is constructed and a direct mail survey is conducted in the greater Cincinnati/tri‐state region. The data collected are analyzed with SAS software using contingency tables with Fisher's exact test and a logistic regression analysis method.

The results show strong correlations between a lean production system and some of the major maintenance variables and parameters such as annual costs of maintenance personnel, parts/materials, and training.

The results of this study can be used as a guideline for engineers, experts and managers in order to monitor the maintenance operation during the transition process from a non‐lean to a lean production system.

This paper sets out to test the claim made in the lean production literature that the lean production system is universally applicable. The proponents of the lean production model insist that it will supersede both mass production and specialised batch production; but this paper argues that, whilst lean production practices have been adopted and adapted by many producers, batch production has an enduring value from both a work design and a manufacturing process design perspective. The paper reviews the evidence for the persistence of batch production and of craft work methods in both luxury vehicle manufacture and specialty component manufacture and highlights the conditions under which batch production remains viable.

Faced with increasing global competition and growing customer expectations, manufacturers looking for significant performance improvements often look to one of the two choices: implementing an enterprise resource planning (ERP) system, or applying the tools and techniques associated with lean production. In fact, many companies are today applying both approaches in an attempt to realise competitive advantage in the global marketplace. However, there seems to be an ongoing debate within the academic literature as to whether lean and ERP are complimentary or contradictory technologies. This paper aims to present a thorough and critical review of literature with the objective of bringing out pertinent factors and useful insights into the role and implications of ERP systems in lean production and to develop a research framework that can be used by researchers and practitioners for studying the value of integrating ERP with lean.

The research methodology employed is literature survey. Literature has been collected primarily through journals within the area of operations management. For rigorousness, textbooks, conference papers, white papers and dissertations have been excluded from the subsequent analysis. Though older literature has been considered to define the scope of this investigation, only literature published after the year 2000 has been considered in the analysis in order to be current in the research field.

The paper proposes a classification scheme for the current research on ERP and lean production, which identifies six major areas in the extant literature. The literature survey is used to find existing research gaps and provides a research framework for future research directions regarding applications and implications of ERP systems in lean production.

This paper fulfils an identified need to study the interactions between ERP systems and lean production.

This paper aims to conduct case studies in companies of different branches of the agribusiness sector to analyze the degree of adherence to lean production system, considering the use of techniques and tools, and how the specificities of the agribusiness system work.

By contributing to the refinement of the theory, multiple type case studies were conducted in eight agribusiness units from different branches by applying structured interviews, on-site visits and document analysis. The comparative analysis of the cases occurred focusing on the degree of adherence to lean production system; use of techniques and tools; and influence of the specificities of agribusiness systems.

The adoption of lean production system occurs as an improvement mechanism of organizational performance. However, it is necessary to advance in the formalization of the actions, which need to encourage the creation of new leaders who spread the organizational philosophy. When comparing the degree of adherence to lean production with the use of techniques and tools, it was observed that there is no direct relationship, indicating that each organization should select only the techniques and tools that will improve their own organizational performance. At last, the specific characteristics of seasonality of consumption, quality and health surveillance and sociological aspects of the food have high influence on surveyed agribusiness systems, and its effects can be minimized by the techniques and tools associated with lean production system.

The analysis is valid for the universe investigated due to the specific characteristic of the case study.

The literature regarding the lean production philosophy is vast; however, the agribusiness segment, one of the major sectors of the global economy, features a large gap in literature. This study is one of the first original papers to report this reality.

The lean production system and world class manufacturing (WCM) have been prominent in recent studies due to their conceptual synergy. However, although the number of studies is increasing, the research is immature, especially regarding the interaction between topics. Therefore, the purpose of this paper is to rank the tools of the lean production system, indicating how they help organizations achieve WCM, using the theory of grey systems.

Therefore, the authors conducted an initial survey to collect data to determine how the lean production tools are related to the WCM pillars. These data were analyzed by the grey relational analysis statistical method, which passes through the construction of four stages.

The results show that of the lean production tools, stream mapping, kaizen, total productive maintenance, Six Sigma, standardized work and 5S stand out for their use and implementation in the organizational environment and facilitate organizations’ transitions to world-class performance through the WCM pillars.

The results achieved guide organizations to use the tools of the lean production system to help them reach world class status.

This paper stands out in the field of operations management, specifically in the research on lean production, by making use of the theory of grey correlation system in an innovative and original way. In addition, it promotes the consolidation of information on two of the main administrative strategies currently employed in the organizational environment.

This paper aims to explore the lean production paradigm as promoter of workers' creativity and thinking potential, and recognize this human potential as a fundamental asset for companies' growth and success, being a major factor to face the disturbing and unpredictable needs of current markets, providing companies with the necessary agility. The authors believe these thinkers are the base for an agile company and learning organization.

The objectives were achieved through a deep literature review, starting with the Toyota production system (TPS) origins. Some industrial lean case studies were also explored to show that the adoption of a lean culture promotes a pro‐active attitude and behavior that are so important for companies nowadays.

This paper explores the association between lean production and the promotion of thinkers. For a long period, and even nowadays, it is common to consider the worker as just another production factor that the companies explore to obtain the maximum utilization. This was a result from the distorted knowledge of the Taylor principles and the Ford assembly line model, seeing the worker as a gear in the “big machine”. Lean production was seen, for many years and by many authors, as an extension of this Taylorist/Fordist model but this paper highlights lean production as a work organization model where the worker assumes a position of thinker, continuously looking for improvement and continuously looking for wastes. By reducing wastes, the company will be prepared to accommodate changes and will attain agility.

This paper is mainly based on literature review and on some industrial case studies of lean implementations (recent or just a few years ago); a deep research is necessary on the cause‐effect relation between lean production adoption and promotion of thinkers.

Helping companies to recognize the importance of workers as thinkers will have relevant impacts through the reduction of waste and costs, improving quality and increase productivity and revenue. Also, for workers, this recognition means respect, self‐esteem and confidence, and, essentially, more satisfaction with work.

With lean production and agility, better products will quickly reach society, contributing thus to clients' satisfaction. Also, lean companies' CEO and workers looking for wastes will lead to a reduction of energy consumption, raw materials needs and gas emissions (reducing pollution of air, land and water), producing only what is needed. Being satisfied with their work they will be happier contributing to the raising of the country's happiness.

The purpose of this paper is to present a dynamic model to measure the degree of system’s leanness under dynamic demand conditions using a novel integrated metric.

The multi-stage production system model is based on a system dynamics approach. The leanness level is measured using a new developed integrated metric that combines efficiency, WIP performance as well as service level. The analysis includes design of experiment technique at the initial analysis to examine the most significant parameters impacting the leanness score and then followed by examining different dynamic demand scenarios. Two scenarios were examined: one focussed low demand variation with various means (testing the impact of demand volumes) while the second focussed on high demand variation with constant means (testing the impact of demand variability).

Results using the data from a real case study indicated that given the model parameters, demand rate has the highest impact on leanness score dynamics. The next phase of the analysis thus focussed on investigating the effect of demand dynamics on the leanness score. The analysis highlighted the different effects of demand variability and volumes on the leanness score and its different components leading to various demand and production management recommendations in this dynamic environment.

The presented lean management policies and recommendations are verified within the scope of similar systems to the considered company in terms of manufacturing settings and demand environment. Further research will be carried to extend the dynamic model to other dynamic manufacturing and service settings.

The developed metric can be used not only to assess the leanness level of the systems which is very critical to lean practitioners but also can be used to track lean implementation progress. In addition, the presented analysis outlined various demand management as well as lean implementation policies that can improve the system leanness level and overall performance.

The presented research develops a novel integrated metric and adds to the few literature on dynamic analysis of lean systems. Furthermore, the conducted analysis revealed some new aspects in understanding the relation between demand (variability and volume) and the leanness level of the systems. This will aid lean practitioners to set better demand and production management policies in today’s dynamic environment as well as take better decisions concerning lean technology investments.

This paper aims to present a conceptual model, called LOOP, an acronym for Leadership, Organization, Operation and People, regarding the pull system implementation in Lean companies. Lean should be holistically implemented to achieve the performance for what it is known. Pull is one of the Lean thinking principles, and it is the production control system underneath the Lean philosophy. However, to implement pull, an organizational transformation in companies’ different areas is needed.

This model was developed following up a case study of a representative example of a multinational company which has been implementing Lean for a long time but without achieving a well-succeeded pull implementation.

Based on that, the authors developed the LOOP model that is an integrated framework with the goal to promote a Lean culture, which includes four dimensions: leadership, organization, operation and people.

Based on the LOOP conceptual model, a different, and hopefully more effective, perspective is presented, establishing some proposals for the four dimensions and for the production and control system selection criteria to implement Lean.

Although leanness is certainly not a new concept it is doubtless still relevant. Interestingly, newly developed manufacturing paradigms and systems are always examined in relation to leanness. In other words, leanness serves in most cases as the landmark paradigm with which comparisons are being drawn between the latter and recently pioneered approaches. The purpose of this paper is to highlight the evolutional orbit that leanness has followed over the years and serve as a herald of the current state of this evolution, which will be discussed further, in a separate paper.

A great part of this paper is devoted to highlighting the misconceptions surrounding issues such as what leanness really constitutes and what are the key concepts and practices that leanness encompasses. Two successful lean transition stories are presented showing how these lean tools and techniques were implemented in the cases of two UK‐based manufacturing companies.

Because of its inherently dynamic nature, leanness has undergone and still is undergoing a process of continuous and never‐ending evolution, the current state of which is expressed in the form of the lean enterprise model. Nevertheless, despite the undiminished attention and interest for leanness, the literature has failed to keep track of this evolution. For this reason a significant proportion of the literature relies on a rather antiquated vision of leanness.

The paper reviews two major waves of literature criticising leanness with the first focusing on its social aspects and the second questioning its universality mainly with respect to its limited applicability in high variety‐low volume production systems.

This study aims to investigate the interrelationships between lean production, green technology adoption, green product innovation, social sustainability performance and green competitiveness. The study further investigates the mediation roles of green technology adoption and green product innovation between lean production systems, social sustainability performance and green competitiveness.

The quantitative research approach is used for the study. Data for the study is garnered from 197 managers of manufacturing firms in Ghana via a self-administered questionnaire. Structural equation modeling, specifically partial least square is applied as the methodological tool to test all hypotheses.

Results of the study suggest that lean production systems have a significant positive impact on green technology adoption, green product innovation and green competitiveness. However, lean production systems are found to have an insignificant impact on social performance. The results further confirm the mediation roles of both green technology adoption and green product innovation between lean production systems, social sustainability performance and green competitiveness; thus indicating that lean production systems create an efficient condition for firms to adopt green technologies and produce innovative green-based products to leverage superior social sustainability performance and green competitiveness.

This study proposes and develops a comprehensive research model that is supported by the natural resource-based view theory to investigate the link between lean production systems, green technology adoption, green product innovation, social sustainability performance and green competitiveness from an emergent country perspective.
