Nowadays companies are trying to become 'greener', which requires integrating the environmental dimension into their traditional performance metrics. However, managers may not have the complete information and data for their environmental problems and, crucially, there is a lack of knowledge about how these environmental issues affect a company's productivity. Even though the availability of technology has increased and it is easier than ever to obtain all kinds of data, there is a lack of agreement on how to correctly measure environmental performance, and companies could suffer from an overload of environmental information. The biggest challenge, therefore, lies in how to measure and obtain the appropriate environmental data and how to interpret and relate these data to the company's productivity. In this context, this paper presents a new and innovative approach, called Plug&Glean, for diagnosing and improving productivity and environmental performance in a defined production system. The approach is applied to a case study in the north of Spain. The findings suggest that it is possible to improve productivity and environmental performance at the same time, as well as reinforce the notion that waste elimination has a positive impact on improving environmental performance.

This paper assesses the effectiveness in scheduling independent jobs with earliness/tardiness costs and variable setup times applying the Overall Equipment Effectiveness (OEE). The OEE is a common metric for measuring the manufacturing productivity. We defined a mixed-integer linear programming formulation of the parallel machine scheduling problem with four different objective functions in order to compare different scheduling configurations. Real data, from a plastic container manufacturing company located in the Basque Country (Spain), were used to validate this approach. A sensitivity analysis was performed with different production capacities and earliness/tardiness costs in order to evaluate the trade-offs between economic performance (i.e., costs) and the partial rates of OEE (i.e., quality, performance and availability). The objective of this study is to propose a guideline to help management make decisions regarding the measurement and improvement of scheduling effectiveness through contemplating earliness, tardiness and variable setup times.

Purpose-The purpose of this paper is to analyze gaps and trends, as well suggest approaches andmethodologies that should be addressed by future studies for implementing the lean and green managementin the agri-food sector. Design/methodology/approach-Based on a sample with 117 papers, this paper presents a systematicreview on the integration of lean and green in the agri-food sector. Findings-Key findings indicate that research on lean and greentopics has increased in recent years, an importantgapintheintegrationofleanandgreenintheagri-foodsector has been identified. Two paths that remain open forfurther research are detected: the lack of theoretical, prescriptive and quantitative research and the possibility ofintegrating the two most used tools of lean (i.e. value stream mapping) and green (i.e. life-cycle assessment). Practical implications-This study does not only advance the theoretical knowledge of the lean and greenfield, but it is also beneficial for agri-food companies who aim to effectively deploy lean and green in theirprocesses in order to improve both operational and environmental performances. Social implications-No other industry matches in such a complete way the agri-food industry¿s challengeof sustainability that is due to the amount of resources it consumes and its interrelatedness with thewell-being of humanity. Originality/value-There are separate streams of established research on lean and green management inthe agri-food sector,

Digitalization is impacting almost every aspect of people¿s life and is greatly affecting supply chain processes. At the same time, supply chains are becoming progressively more aware of their impacts on people, the planet and profits (triple bottom line perspective) and the concept of sustainable supply chain has received increasing attention among scholars and practitioners. In this context, this article aims to analyze scientific research on supply chain management in the field of sustainability and digitalization using a bibliometric approach. To this end, this article analyses 484 papers from Scopus database according to the following parameters: chronology, discipline, source, center, country and citations. The dataset consisted of articles from scientific journals published over the period 2002¿2018. In addition, VOSviewer software is used to map the bibliographic material using the co-occurrence of keywords and most influential journals. The analysis reveals that: sustainability and digitalization are important emerging fields within supply chains that have increased significantly during the last ten years; the USA is the most influential country; and the topic is structured around 2 clusters (1) Supply chain management, concepts and practices and (2) energy related technologies. The results may facilitate the planning, designing, running and publishing of future research on this topic.

Small and medium enterprises (SMEs) are key actors in the implementation of the circular economy (CE) concept as a basis for creating sustainable societies. Thus, the main objective of this study is to identify key strategies and resources that may favor CE implementation in SMEs. These key strategies should encourage SMEs to develop eco-innovations to gain competitive advantage and create and capture value that is coherent with nature. A mixed-method approach that consisted of a literature review and a focus group for gathering qualitative data was used. This focus group was made up of experts such as researchers and practitioners from universities, sustainable SMEs, and consultancy firms in Spain. A set of strategies and internal and external factors were identified to help SMEs to implement the CE. Finally, some useful dynamic capabilities for implementing the CE in business performance were identified.

Purpose Environmental management (EM) is becoming increasingly important in all types of organizations. The food industry represents the top industrial sector of the Spanish economy; however, there is still little knowledge about how it is managed environmentally. The purpose of this paper is to present a descriptive analysis of the Spanish food sector. Design/methodology/approach This study undertook a descriptive analysis based on probabilistic sampling surveys from food companies in Spain. The survey was sent out to 900 companies obtaining 128 answers. Findings The results of this study show that companies with an EM standard tend to have a more developed system and a greater presence of EM tools and actions. Moreover, statistical differences were identified among the characteristics of companies and various factors that affect the evolution of their EM. Originality/value There are no studies that reveal a clear picture of the status of EM in the Spanish food industry. This study presents a clear starting point that might help policy makers, consultants, researchers and other parties to set new improvement routes so companies do not get stuck in their progress toward environmental excellence

Manufacturers have become progressively more aware of their operations' impacts on the triple bottom line (social, environmental and financial), and they are under increased pressure to account for their resource consumption and environmental footprint. These challenges are forcing companies to implement and combine different management approaches, such as "green" and "lean", to meet the needs of the ever-changing market demand. Using semi-structured interviews in 58 different companies, this paper shows how manufacturing companies carry out manufacturing and environmental practices. This study contributes to the current debate in the literature on environmentally friendly manufacturing by arguing that companies with advanced manufacturing practices do not engage in proactive participation in environmental management with tactical and strategic practices inside their organizations. Following that, some considerations for correctly measuring the environmental efficiency in companies are presented. The findings and recommendations of this study can be used to fully utilize the potential of environmental practices to simultaneously improve manufacturing productivity and environmental performance and to identify trends in organizational development.

The transport of goods is essential for the economic growth of cities and regions. Urban freight transportation makes up a very small percentage of the total transportation time for goods, but it can represent up to 28% of total transportation costs. To reduce overall costs and increase revenue from this operation, one common methodology used by decision makers is the optimization models. This paper proposes a new methodology for evaluating the effectiveness of urban freight transportation systems using the OEE (Overall Equipment Effectiveness) metric, a well-known rate used in the Lean Manufacturing framework. The methodology uses a mathematical model with several objective functions, two of which are multi-objective, to explore the relationships and trade-offs between economic development, quality, performance and availability (partial rates of the OEE). The final objective is to optimize the OEE metrics and the profitability of a transportation system. This methodology was tested using real data from the city of Bogota, Colombia. Experiments were run with different companies, costs, demands and travel times in order to validate the proposed approach. The results show the benefits of using multi-objective functions to optimize both OEE (quality, performance and availability metrics) and profits. The proposed methodology provides an 'ex ante' evaluation of the tactical and operational decisions made by companies in configuring an urban freight transport system.

The purpose of this paper is to develop a methodology that is based on the concept of environmental comfort and can serve as a tool that can help companies and employees to implement Kaizen projects. This methodology focuses on the worker¿s participation in analyzing and developing improvements related to their workplace. Design/methodology/approach This research is focused on the development of a methodology that encourages worker participation in improvement activities, through the analysis of their working conditions. For this purpose, the proposed methodology was developed in accordance with the dimensions of workplace comfort proposed by Vischer. The employees start working on the analysis of problems and their solutions through the logical framework approach, as it is a tool that encourages worker participation and consensus. The developed methodology was applied in a company, with three different groups of people, which enabled the authors to test its utility. Findings The findings reveal that the proposed methodology is effective in initiating workers in the path of Kaizen. The employees who applied this methodology were able to propose improvement actions that addressed the problems and opportunities that they had previously detected. Moreover, the questionnaire that was used to validate the methodology and was administered to employees shows that the methodology is useful in preparing them for adopting continuous improvement (CI) programs.

This paper aims to improve the applicability and relevance of contingency theory research in the field of Operations Management. Based on the results of previous studies, we have identified a systems-based single definition of organisation types that could describe the fit between organisational environment and organisational structure. This definition of organisation type, which we call an 'organisational system', regards the organisation as an integrated whole instead of as a sum of its parts and can help to better classify organisations in order to identify fits between organisation types and emerging practices in Operations Management.

Purpose: This research analyzes the maturity of environmental management as well as the degree of to which the Circular Economy has been implemented in Basque SMEs. Design/methodology/approach: A total of 17 case studies were carried out in industrial SMEs companies in the Basque Country. Findings: The main results show that companies are limited to complying with the law and in many cases are worried about the image of the company, although they are not committed to environmental issues. There is still a lot to do in SMEs, as they are the companies that face the biggest challenges due to a lack of resources. Originality/value: Circular Economy aims to change a linear economy into promoting sustainability of the economy while also engaging in sustainable environmental protection. This research has focused on small and medium enterprises as they represent a 99% of companies in Europe and they are the ones that have the most difficulty reaching a stage of environmental excellence due to their limited resources.

Most studies regarding real scheduling constraints only consider the constraints related to the specific manufacturing environment studied, limiting the possibility of drawing general conclusions. A survey of 50 companies was conducted in order to discover which constraints were present and what their relationship was with the scheduling context. This paper investigates which practical scheduling constraints are present in the manufacturing industry and whether the scheduling task is context-dependent. Results of this study show that some practical production constraints are context-dependent.

The 5S methodology is a very appropriate way to initiate and achieve the process of continuous improvement. This paper studies management practices in successful Japanese companies in order to determine what 5S principles are behind them. After visiting and conducting interviews at five different plants, a multi-case study analysis was developed to identify the key aspects of the success of the implementation of 5S in Japan. Although each of the companies studied is different, there are commonalities that provide for interesting learning. As a result, best managerial practices based on 5S principles are explained, and the most important principles associated with the success of the 5S method are described and discussed.

Teamwork is one of the most powerful tools to ensure success across any activity. The purpose of this paper is to examine the factors that actively contribute to the effectiveness of teams. This research looks at two different types of teams: care delivery teams representing healthcare and improvement teams representing the manufacturing industry. The aim is to provide greater knowledge about the application of team work factors in different environments. Design/methodology/approach -- Qualitative interviews about teamwork factors were conducted with 17 leaders of teams from healthcare and 22 leaders from manufacturing industries. The responses were categorized into different levels according to the application of each factor. Then, the factors were analyzed to draw conclusions about the different approaches to teamwork and their application. Findings -- Most of the factors analyzed are highly applied in both sectors. However, we found significant differences between hospitals and the manufacturing industry when it comes to factors such as strategies, feedback on results, leadership, participation and communication. Originality/value -- Measuring each factor in two different sectors (healthcare and industry) has yielded noteworthy findings and the best practices for their implementation

Lean manufacturing has been increasingly applied by leading manufacturing companies throughout the world, led by the major automobile manufacturers and their equipment suppliers. The aim of this case study is to show the applicability of lean manufacturing¿s body of knowledge to a different environment: a seasonal food industry. Several techniques and analyses such as value stream mapping (VSM), overall equipment efficiency, spaghetti diagrams, work balance, and discrete event simulation were applied in this case study. Some of the improvement ideas resulting from the tools used were tested in the field to corroborate the findings. Finally, the future state VSM was mapped, where most of the improvement ideas identified throughout the project were consolidated. Whether the path to improvement is marked by increased spending on systems and machinery, human capital, or both, engineers and managers in the frontlines of food production recognize that improvement is a quest and not a destination. Although process industries need a special version of lean manufacturing tools, this case study shows how, with slight modification, several tools can be applied to the seasonal traditional craft industry.

Sectors associated with the distribution of products and goods have become more and more important in recent years. Globalisation and changing market demands are increasing competitiveness in these sectors, and as a result many companies have adopted new improvement methods to assure their survival. The adoption of improvement philosophies and a lean culture offer new opportunities to improve the quality and service of distribution networks and activities related with transport and warehousing. The application of these philosophies, widely used in industrial companies, has been little documented in distribution centres. However, these methods are difficult to implement in companies from the distribution sector due to the volatility of customer demand, the high degree of human participation and the demanding mechanical and repetitive activities in retail and storage activities. This paper presents a methodology for change management to adopt lean practices in distribution centres. The presented case study has been used to develop, test and refine the methodology. Results show that the methodology was suitable for establishing a lean culture in the company and it resulted in good outcomes in terms of productivity, employee attitudes and participation.

The purpose of this paper is twofold: to evaluate the importance of the factors reported in the literature as enablers of Continuous Improvement (CI) programmes and to determine the perception of managers of different companies in the Basque Country and Navarre (Spain) regarding the relevance of these factors to their improvement programmes. In total, 15 elements have been considered to be key issues for the sustainability of CI programmes. Semi-structured interviews were conducted with 36 companies in order to assess how the companies value the factors and how the factors are applied and measured. The findings regarding the application and evaluation of such factors have revealed that companies are focused on the agents associated with the achievement of results. Other factors, such as management commitment or the promotion of team working, are highly scored and applied, but few companies evaluate them or take actions to improve their application. This paper analyzes the application of some factors considered to be enablers or key factors for the sustainability of continuous improvement systems. Furthermore, it examines the mechanisms or indicators which are used by some companies to measure the application of those factors

By means of a case study of an automotive manufacturer, this paper aims to study the impact of a continuous improvement (CI) programme on quality defects. The analysis aims to ascertain if several independent variables such as production, CIs, and shifts are correlated to each of two dependent variables: internal quality defects and auditor quality defects (detected in the line). We gathered daily data for each shift of internal quality and auditor quality in a 12-month period. The defects considered and analysed through this study amounted to more than 68,000. This analysis could be useful as a methodology to evaluate the CI programmes of other manufacturers, since there is very little literature in terms of case studies or examples that focus on the daily struggle that manufacturers face when transforming these strategies into working practices

Many researchers consider absenteeism to be a significant problem for employers. Absenteeism lowers the overall level of worker expertise, which may affect product quality and trigger an increase in customer complaints. This research was carried out in a prominent automobile manufacturing company, with an assembly line¿driven rigid production process. This article gathered customer quality complaints registered during the 17 months after cars were delivered to customers, from one year of car production, to analyze how employee absenteeism affects customer quality complaints. The empirical evidence presented by this research in the automotive industry confirms that absenteeism does not lead, necessarily, to a decrease in quality. This evidence must make organization redefine the value of their expert workers. Moreover, these results could have an impact on assembly-line design and the use of worker job-rotation programs for technologically sophisticated assembly lines.

Purpose ¿ Since the field of healthcare was a latecomer to the quality movement, knowledge transfer has generally flowed in one direction, from industry to healthcare. However, organisations can also be enriched by healthcare. In particular, this paper aims to show industry that important lessons can be learned regarding how teamwork is generally managed within healthcare. Design/methodology/approach ¿ To identify the useful lessons that healthcare can teach industry, the authors started with a brainstorming session among the members of the research team to pin-point the lessons based on their experience with healthcare and industrial environments. Afterwards, an exhaustive review of the relevant literature from the last ten years was carried out. Findings ¿ Industrial organisations need to develop teamwork frameworks focused on involving every employee in cross-disciplinary, empowered and trained teams. Moreover, from a team perspective, special care must be shown when defining clear roles, focusing on end clients, formulating shared objectives and facilitating internal communications. Practical implications ¿ The ten lessons from healthcare teamwork best practices believed to be the most important are given in the paper. Although some of these lessons may not be completely new concepts for industrial organisations, the paper shows how healthcare develops, spreads and applies these concepts in the real world. Originality/value ¿ The paper summarises, in ten useful lessons for organisations, healthcare's best teamwork practices in the literature

In this paper, the use of a graphical simulator called TOCNUN is presented. It helps users to understand plant operations conducted under the philosophy of Theory of Constraints (TOC) developed by Goldratt. TOCNUN is an alternative tool developed to support the teaching of TOC in just six or seven steps, which correspond to six or seven, 90-min learning sessions, including theory. This paper illustrates the structure for practical sessions that should be carried out with the simulator. Finally, validation input from undergraduate students and company managers is presented.

Después de los planteamientos de Taylor y Ford, la industria japonesa, con su principal exponente Toyota, demostró que es posible tener un mayor nivel de flexibilidad y productividad a través de sus principios de Just in Time, polivalencia de la mano de obra, cero inventarios, producción en flujo continuo y mejora continua. Diversidad de conceptos, propuestas y hasta filosofías han surgido de las ideas originales de Taiichi Ohno y sus colaboradores y, en muchos casos, al querer ser implantados en la organización se pierde la esencia de lo verdaderamente importante. La finalidad de este artículo, resultado de una revisión bibliográfica sobre sistemas de mejora continua, es mostrar cómo interactúan los diferentes planteamientos desarrollados en torno al Sistema de Producción Toyota, y al mismo poner de relieve sus aspectos comunes y los puntos críticos a considerar en su implementación. Para tal fin, se ha recurrido a los conceptos originales de los principales autores como son Taiichi Ohno, Masaaki Imai, Hiroyuki Hirano, Shigeo Shingo, James Womack y Daniel Jones, todos ellos considerados gurúes de la mejora continua. Así, el artículo contribuye a una comprensión holística sobre la aplicación de los sistemas de mejora continua.Como síntesis conclusiva se extrae que, además del despilfarro considerado el centro de atención de los diferentes planteamientos, existe también un interés general por lograr la participación del personal en los programas de mejora a través del cambio de hábitos, capacitar permanente al personal en los fundamentos y técnicas sobre mejora, romper el círculo vicioso que asocia la mejora continua con la pérdida del empleo y, finalmente, generar un cambio de mentalidad como precondición al comenzar a implantar un programa de mejora continua. En este mismo sentido, la gestión de los procesos y el aprendizaje de las personas son dos aspectos que conducen, de manera interrelacionada, a que una organización mejore su productividad y competitividad.

Equipment efficiency can be measured and improved by the availability, performance and quality rates provided by the overall equipment effectiveness (OEE) metric. Because today's managers operate in a complex manufacturing scenario, measurement systems play an important role in transforming data into decisions, and this task needs to be strengthened. Although sophisticated equipment and information technology systems are available, a methodology is required for understanding and managing data in order to make timely decisions regarding improvement. Thus, improvement needs to be supported by an easy-to-understand measurement system and a cutting-edge data-collecting technique. In order to assist not only managers and operators but also students and academia, this article presents a Plug&Lean system supported by a core element, the Plug&Lean wireless device, based on total productivity maintenance (TPM) and Lean methodology for providing a reliable diagnosis of the current state of equipment, to display graphical information about the equipment performance constraints towards to direct improvements activities. The aim of the Plug and Lean wireless device is to collect accuracy data with less effort from production equipment Two case studies are discussed to illustrate the applicability of the system.

After Taylor and Ford's approaches, the Japanese industry, with its main leading exponent Toyota, showed that it is possible to have a greater level of flexibility and productivity through its principles of "just in time, versatility of labor, any inventory, continuous flow production and continuous improvement. Diversity of concepts, proposals and even philosophies have arisen from the original ideas of Taiichi Ohno and his associates, however, when they are going to be implemented in a organization its key essence is lost. The purpose of this paper, result of a review of the literature on continuous improvement systems, is to show how different approaches developed around the Toyota Production System interact. At the same time to emphasize in their common and decisive points to consider in its implementation. For this task, it has to be turned to original concepts of the leading authors such as Taiichi Ohno, Masaaki Imai, Hiroyuki Hirano, Shigeo Shingo, James Womack and Daniel Jones. All of them known such as gurus in the field of continuous improvement. Thus, this article contributes to a holistic understanding on continuous improvement systems implementation. As a conclusion, besides the wasting considered the focus of attention of different approaches, there is also a general interest in engaging staff in improvement programs through the change of habits, permanent staff training in the improvement fundamentals and techniques, leaving behind the vicious circle that links continuous improvement with a condition of lacking work, and finally motivate a change of mind, create a climate of trust before starting to implement a continuous improvement program. In this sense, the management processes and the learning of employees working in harmony are two aspects that lead an organization to improve in both: productivity as competitiveness.

Introduction To investigate the adoption and transfer of some good practices in the Construction Sector is the aim of the following research. The GRAI Methodology and the DGRAI technique are associated to improve the operational performance of the supply chain. They are already known and have been studied by researchers; however the development of these techniques in the field of Construction has not been so deep. Method The proposed research method is based on Action Research. This is a variant of Case Studies in which the researchers are involved in the changing process. This method has been chosen because it is a theory extension or refinement. In the last three years the researchers have been involved in using an experimental model that uses GRAI and DGRAI for the diagnosis, strategy formulation and deploy of these practices to improve the performance of one top firms related to Construction sector. Results Two years after the starting up of the reengineering process has improved the Quality of Service and reduced fixed costs due to the reduction of stocks needed. Conclusion It has shown that the benefits of subcontractors and suppliers integration, the improvement of planning and control system of the extended enterprise aided by GRAI and DGRAI as well as Action Research utility for this type of Research are completely demonstrated.

Este artículo analiza el grado de sostenibilidad de las empresas en la gestión de la mejora continua y los factores que apoyan la sostenibilidad en el tiempo, a través de una encuesta enviada a 350 empresas de la Comunidad Autónoma Vasca y Navarra durante el mes de junio de 2009. El estudio presenta datos sobre la evolución de los sistemas de mejora en los últimos años, y la implantación de las distintas metodologías utilizadas. A continuación realiza un análisis de los factores que las empresas asocian con el abandono de los sistemas de mejora. Dado que los sistemas de mejora se basan en la participación de las personas, el estudio caracteriza cómo es dicha participación. Finalmente se analizan los elementos que las empresas utilizan en sus sistemas de mejora, y en qué grado se han introducido indicadores y objetivos en la gestión de la mejora. Como conclusiones se apuntan las siguientes claves para la mejora sostenible: una mayor implicación del personal directo en el sistema de mejora continua, la integración del sistema de mejora continua en la organización y el establecimiento de indicadores asociados al sistema.

Libro:  Industrial Symbiosis for the Circular Economy
2020  págs. 27 - 41
Most companies operate on a linear economy that consists of ¿take, make, use and waste.¿ However, the growing impact of industries¿ emissions on the environment has aroused global concerns about their activities. As a result, companies are increasingly aware of the importance of implementing a circular economy (CE) with environmental, social and economic beneficial results. In this transition to a circular system, companies will need guidance, especially in the case of small and medium-sized enterprises (SMEs), which are the predominant type of company in the Organisation for Economic Co-operation and Development (OECD) area. Taking this into account, the objective of this chapter is to provide SMEs with a methodology to understand the value of CE for their corporate strategy, diagnose their business and design an action plan to facilitate the transition to the CE, allowing them to create value and gain a competitive advantage in the market. The CE could be addressed through six fields of action: take, make, distribute, use and recover goods and materials (Park et al. in J Clean Prod 18:1492¿1499, 2010; Stahel in Nature 24:6¿9, 2016), and a transversal field of action called industrial symbiosis. These six fields of action are the methodology¿s backbone. The CE methodology for an SME consists of the following steps: Diagnose the company¿s situation, through reflection on the current value proposal, the stakeholders and a preliminary diagnosis regarding its level of CE application through a proposed diagnosis tool. Analyze barriers and opportunities derived from the application of the CE. Propose a CE implementation plan. This chapter will explain, the process followed, and the various results obtained in the rubber-metal company. The proposed methodology makes an important contribution to SMEs¿ professionals regarding the step-by-step implementation of the CE using a real case that shows how to identify, plan and capitalize on the opportunities of the circular economy. The case study reveals how SMEs can start implementing the paradigm shift through environmental strategies that do not usually require high amounts of financial resources or technology. Moreover, the case study also highlights the relevance of the CE for creating value and a competitive strategy in the market.

Nowadays, urban freight transport networks must be environmentally sustainable. As a consequence, collaboration strategies have been implemented as one alternative to enhance the efficiency of the supply chain and to reduce its environmental burden. However, there is a lack of knowledge about how to correctly quantify the environmental impact of collaborative urban freight transport networks. To fill this gap, we present an optimization approach for evaluating the environmental performance of collaborative systems by applying the Overall Greenness Performance (OGP) tool. We illustrate our approach using real data from the city of Bogotá, Colombia. Our results provide insights for shifting towards sustainable freight transportation networks. For example, we quantify savings up to 11% of CO2 emissions after applying collaboration in urban transportation contexts.

The increase in environmental and social awareness has triggered numerous green initiatives at companies. Traditionally, companies¿ training related to environmental management focuses on technical aspects and theoretical concepts. In addition to these theoretical contents, it is necessary to carry out practical activities to impart the desired behaviors and skills. Serious games have been found to improve employees understanding of practical environmental sustainability challenges, by offering opportunities to obtain first-hand experiences that may otherwise be too costly and difficult to reproduce in reality. This work presents Pizz@green, a serious game which simulates the productive and environmental efficiencies generated by the improvements of processes in a pizza shop. The purpose of the game is the practical learning of the environmental impact caused by the production processes of a company.

Manufacturers have the challenge to increase productivity given complex manufacturing environments. A source that provides substantial levels of productivity is the overall equipment effectiveness (OEE) metric, which is an indicator to improve not only equipment utilization; but also the overall manufacturing operations, because of the valuable information that comes from the availability, performance and quality rates. Although information technologies have been introduced, companies use manually recorder data and have complicated measurement procedures. As a consequence, inaccurate information is generated and opportunities to improve productivity are missed. This paper presents a continuous improvement framework based on Lean manufacturing philosophy, operated by a system of wireless devices to support the real time equipment performance metrics. In order to validate the framework, results of a case study are exposed.

Manufacturers continue facing the never ending challenge of finding the best way to increase productivity levels in order to remain competitive. Significant level of productivity are given by the efficient utilization of production equipment, thus manufacturing companies use the overall equipment effectiveness (OEE) rate as an indicator to control equipment utilization related to the maintenance activity; however they do not take into account other valuable OEE-information to improve their entire manufacturing operations. This paper presents a continuous improvement model Plug&Lean-CiMo, whose aims are the accurate calculation of the OEE indicators, the appropriate classification of losses, and the systematic integration of lean manufacturing philosophy tools in an improvement methodology. The model has the advantage of using a portable wireless system to support the automated collection, of data to make the continuous improvement process easier. A case study is presented to illustrate the validation of the model.
