      A constant evolution in the efficiency of production systems and government policies has enabled the control of the environmental impact of production activities and encouraged companies to develop strategies to achieve more sustainable operations. Despite this, more needs to be done to reduce the risks of globalised production activities. In this context, evidence suggests that Lean Manufacturing (LM) and Cleaner Production (CP) make a positive contribution to the environmental performance of organizations. However, very little has been reported in the scholarly literature regarding the convergence and divergence of these two approaches. This work therefore attempts to take advantage of the synergies of LM and CP by proposing a Lean Cleaner Production Benchmarking (LCPB) method to assess the practices and culture regarding the application of CP in companies. The method considers the management aspects of people, information, products, suppliers and customers, management and processes, as well as the LM practices that contribute to a more eco-efficient production. LCPB uses a methodology based on benchmarking that was applied to 16 Brazilian manufacturing companies in order to assess their practices and performances regarding CP. The method seeks to provide a diagnosis to verify whether CP is effectively carried out by the companies, and what their performances are regarding actions beneficial to the environment. The application of LM practices that contribute to CP was also evaluated through the proposed LCPB method. The paper contributes to the theory by proving further evidence of the compatibility and synergies of LM and CP. In addition, it proposes a novel method that enables the analysis of companies' practices and performances related to CP, assesses their actions associated with sustainability, and contributes to identifying points where there is a lack and difficulty regarding CP. The proposed method helps to relate LM and CP activities, indicating that companies that seek to apply LM concepts are those that present high CP practices and performance.
    • Lean and green in the transport and logistics sector: A case study of simultaneous deployment

      Garza-Reyes, Jose Arturo; Villarreal, Bernardo; Kumar, Vikas; Ruiz, Patricia Molina; The University of Derby (Taylor and Francis, 2016)
      The transport and logistics sector is of vital importance for the stimulation of trade and hence the economic development of nations. However, over the last few years, this sector has taken central stage in the green agenda due to the negative environmental effects derived from its operations. Several disciplines including operations research and sub-areas of supply chain management such as green supply chains, green logistics and reverse logistics have tried to address this problem. However, despite the work undertaken through these disciplines, theoretical or empirical research into the sequential or simultaneous deployment of the lean and green paradigms, particularly, in the road transport and logistics sector is limited. This paper presents a case study where both paradigms have been combined to improve the transport operations of a world leader logistics organisation in the metropolitan area of Monterrey, Mexico. To do this, a systematic methodology and a novel tool called Sustainable Transportation Value Stream Map (STVSM) were proposed. The results obtained from the case study indicate that the concurrent deployment of the green and lean paradigms through such methodology and the STVSM tool is an effective approach to improve both operational efficiency and environmental performance of road transport operations. The paper can be used as a guiding reference for transport and logistics organisations to undertake improvement projects similar to the one presented in this paper. Additionally, this research also intends to stimulate scholarly research into the application of lean and green paradigms in the transport and logistics sector to expand the limited research pursued in this area.
    • Lean and green – a systematic review of the state of the art literature

      Garza-Reyes, Jose Arturo; The University of Derby (Elsevier Ltd., 2015-04)
      The move towards greener operations and products has forced companies to seek alternatives to balance efficiency gains and environmental friendliness in their operations and products. The exploration of the sequential or simultaneous deployment of lean and green initiatives is the results of this balancing action. However, the lean-green topic is relatively new, and it lacks of a clear and structured research definition. Thus, this paper’s main contribution is the offering of a systematic review of the existing literature on lean and green, aimed at providing guidance on the topic, uncovering gaps and inconsistencies in the literature, and finding new paths for research. The paper identifies and structures, through a concept map, six main research streams that comprise both conceptual and empirical research conducted within the context of various organisational functions and industrial sectors. Important issues for future research are then suggested in the form of research questions. The paper’s aim is to also contribute by stimulating scholars to further study this area in depth, which will lead to a better understanding of the compatibility and impact on organisational performance of lean and green initiatives. It also holds important implications for industrialists, who can develop a deeper and richer knowledge on lean and green to help them formulate more effective strategies for their deployment.
    • Lean emergency medical operations

      Villarreal, Bernardo; Granda, Edgar; Lankenau, Andrea Montalvo; Bastidas, Ana Cristina; Garza-Reyes, Jose Arturo; Universidad de Monterray; University of Derby (Industrial Engineering and Operations Management (IEOM) Society, 2017-07)
      The fundamental responsibilities of Emergency Medical Service (EMS) systems are to provide urgent medical care, such as pre-hospital care, and to transport the patient to the hospital if needed. The agility and efficiency of EMS systems are major public concerns. Since the EMS process involved is fundamentally a transportation process, the Lean Transportation approach is a viable option for improving Emergency Medical Service (EMS) operations performance. The identification of waste during the ambulance cycle time is the basis for designing an operations improvement strategy. The scheme utilized uses modified versions of the Transportation Value Stream Map (TVSM) and The Operational Vehicle Effectiveness (TOVE) Index. Thus, availability, performance and quality wastes are identified to define the improvement strategy. Results of the application for the Monterrey metropolitan operations of the Mexican Red Cross are provided.
    • A lean environmental benchmarking (LEB) method for the management of cutting tools

      Tomelero, Roberto Luiz; Ferreira, João Carlos Espíndola; Kumar, Vikas; Garza-Reyes, Jose Arturo; University of Derby (Taylor and Francis, 2017-02-21)
      Manufacturing companies are striving hard to remain competitive hence, they rely on a number of resources to meet customers’ expectations, among which cutting tools are included. This paper addresses the problems faced in the management of cutting tools activities. Production managers have highlighted the lack of procedures containing metrics and targets that would show them whether their company is able to perform an efficient management, and if it is capable of supporting the deployment process. In this context, this paper presents a novel Lean Environmental Benchmarking (LEB) method for performing a diagnosis of practices and performances to support the implementation of a cutting tool management strategy and/or the effective management of these assets. Strategic, technical and logistical aspects are addressed, particularly, with regard to management focused on lean manufacturing and environmental aspects. Field studies were performed in nine Brazilian companies in the metal-mechanical sector to validate the LEB method proposed. The LEB method helped the participant organisations clarify the various activities that involved the management of their cutting tools, while the field studies indicated that all nine organisations had a great concern regarding the preservations of the environment, and also an effective utilisation of resources spent for machining components.
    • A lean implementation framework for the mining industry.

      Seifullina, Aziza; Er, Ahmet; Nadeem, Simon Peter; Garza-Reyes, Jose Arturo; Kumar, Vikas; University of Warwick; University of Derby; University of the West of England (International Federation of Automatic Control, 2018-06)
      The adoption of Lean concepts beyond the manufacturing sector has been increasing recently. In this line, its scope has been expanded to the mining industry under the realisation of the need for productivity improvements and a leverage for efficient operations. Limited research exists regarding Lean implementation in the mining industry in a comprehensive and structured way. This paper therefore follows a systematic approach to review the current literature to identify Lean implementation patterns in the mining sector, its scope, challenges, and limitations. The results reveal the limited utilisation of Lean and that there is a lack of coherent and conceptual models to guide the implementation of Lean in this industry. Hence, the research proposes a framework for Lean implementation in the mining industry.
    • Lean manufacturing adoption in the transport and logistics sector of Thailand – An exploratory study.

      Garza-Reyes, Jose Arturo; Tangkeow, Sarita; Kumar, Vikas; Nadeem, Simon Peter; University of Derby; University of Warwick; University of West England (IEOM Society, 2018-03)
      This paper investigates the adoption status of lean manufacturing (LM) in the transport and logistics sector of Thailand. A survey questionnaire was design, validated and distributed among Thai transport and logistics companies. In total, 120 useable responses were received and analysed using descriptive statistics. The results of the study indicate that the implementation of LM is relatively high, with PDCA, 5S and root cause analysis being the most implemented LM approaches and tools. However, the LM’s implementation was found to be mainly contained within individual departments or improvement projects, rather than being a company’s wide strategy. Main challenges to LM implementation included: organisational structure of companies, misalignment between goals of individuals and their companies, and lack of sustainment of a lean culture. Main benefits were the ability to identify and reduce waste, increased productivity and better organisation of workstations. On the other hand, lack of understanding, knowledge and expertise in LM were the main reasons for not implementing it, plus the use of technology-based tools instead of LM. Non-LM companies showed interest in adopting LM in the future, with JIT, Kaizen and Six Sigma being the most likely to implement. This study is among the very first of its kind. It offers academics, researchers and practitioners interested in LM and/or the transport and logistics sector with some initial evidence of the adoption of LM in this industrial sector of Thailand.
    • Lean manufacturing and environmental performance – exploring the impact and relationship

      Nadeem, Simon Peter; Garza-Reyes, Jose Arturo; Leung, Sin-Ching; Cherrafi, Anass; Anosike, Anthony; Lim, Ming K.; University of Derby; PAL Surface Treatment System Ltd.; Cadi Ayyad University; Coventry University (Springer, 2017-08-29)
      The relationship between Lean Manufacturing and Environmental Performance has attracted much debate but at the same time lack of empirical evidence leaves haphazard opinions on this matter. The objective of this paper is therefore to pro-vide some insight into the impact of Lean Manufacturing on Environmental Per-formance and the existing relationship of these two concepts. Four semi-structured interviews with industrial and academic experts provided a solid ground to suggest that the relationship does exist, despite the fact that these two concepts were developed independently from each other. Being the exploratory nature of this study and its purpose to ignite further research, it does not employ a quantitative approach. The results of this study can help managers to better un-derstand and concurrently tackle both the economic and environmental challenges faced by their organizations.
    • Lean Manufacturing and Internet of Things – A Synergetic or Antagonist Relationship?

      Anosike, Anthony; Alafropatis, Konstantinos; Garza-Reyes, Jose Arturo; Kumar, Anil; Luthra, Sunil; Rocha-Lona, Luis; University of Derby; University of Warwick; London Metropolitan University; Ch. Ranbir Singh State Institute of Engineering & Technology, Jhajjar-124103, Haryana, India; et al. (Elsevier, 2021-04-13)
      This paper explores the relationship between five LM methods (JIT, TPM, Autonomation, VSM and Kaizen) and three IoT technologies (RFID, WSN and Middleware) and the implications that arise from their combination. Four hypotheses and four complimentary research questions were formulated and tested. 136 responses were obtained through a questionnaire survey and analysed using descriptive statistics, 2-Sample proportion, Kruskal-Wallis, ANOVA and Pairwise comparison tests. The findings indicate that IoT can significantly improve the operational performance of manufacturing organisations. The findings advocate that all LM methods, apart from Kaizen, benefit from improved effectiveness by combining them with IoT. The results suggest that this can be attributed to the general perception about IoT, which despite the support and benefits it provides to people, is seen to be reducing human involvement whereas Kaizen is seen to be more people-focused. Improvements in information flow, decision-making and productivity were also found to be the most important motivations and benefits of combining LM methods with IoT. The findings of this research can be used by LM organisations that wish to embark into the new digitalised manufacturing era and businesses seeking to improve their performance through the combination of traditional efficiency-based methods and I4.0 technologies.
    • Lean production myths: An exploratory study

      Saurin, Jose T; Tortorella, G; Soliman, M; Garza-Reyes, Jose Arturo; Universidade Federal do Rio Grande do Sul, Porto Alegre, Brazil; Universidade Federal de Santa Catarina, Florianopolis, Brazil; The University of Melbourne; Universidade Federal de Santa Maria, Santa Maria, Brazil; University of Derby (Emerald, 2020-11-25)
      Tthis paper presents an exploratory investigation of myths on lean production (LP), by identifying, dispelling, and assessing their pervasiveness. A list of myths was proposed mostly based on seminal LP texts and our rich experience from researching, teaching, and consulting in lean journeys. Complexity thinking was adopted as a lens for dispelling the myths, as it challenged generalizations implied in myths. An investigation of the pervasiveness of the myths was conducted, based on a survey with 120 academics and practitioners. Ten myths were identified and dispelled. Survey’s results indicated that belief in lean myths was more common among less experienced practitioners (< 10 years), while experience was not a relevant factor for academics. The lean myths partly reflect the experience of the authors. Furthermore, a larger sample size is necessary for a full analysis of pervasiveness. The lean myths might be underlying barriers to LP implementation (e.g., lack of knowledge of managers and workers), and they might be proactively accounted for in lean training and education programs. This is the first work to explicitly frame a set of lean myths.
    • Lean readiness level of the Azerbaijan construction industry

      Aghayev, Hajibaba; Kumar, Vikas; Rocha-Lona, Luis; González-Aleu, Fernando; Nadeem, Simon; Garza-Reyes, Jose; University of Warwick; University of Derby; University of the West of England; Instituto Politécnico Nacional, Mexico; et al. (IEOM Society, 2020-03)
      This paper identifies and measures the Lean readiness of the Azerbaijan construction industry. A survey questionnaire was utilised to evaluate the Lean readiness of this industry by measuring its quality practices and to test three hypotheses. The Lean readiness framework developed by Al-Najem et al. (2013) was taken as a basis for this study; however, there can also be seen some adaptations made from the framework developed by Diekmann et al. (2003). The questionnaire was sent to 57 Azerbaijan construction companies, from where 20 responses were obtained. The results derived from the questionnaire showed that the Azerbaijan construction industry is not ready to implement the Lean methodology. It also found that there remains a lack of trust between employee and employer relations. Lastly, it is evident that the size of the companies does not play any considerable role on Lean readiness of construction companies and does not make any sense for choosing construction prerequisites. This study can be beneficial for those Azerbaijan construction companies that are interested in the implementation of Lean construction, or which are interested to increase their level of competitiveness.
    • Lean readiness within emergency departments: A conceptual framework

      Al-Najem, Mohammed; Garza-Reyes, J.A.; Antony, J.; University of Derby (Emerald, 2019-08-05)
      The purpose of this study was to develop a framework to assess the lean readiness within emergency departments (EDs) and identify the key quality practices deemed essential for lean system (LS) implementation. An extensive review of lean healthcare literature was conducted, including LS implementation within the healthcare sector (both generally and in EDs), best ED quality practices, essential factors for LS implementation within healthcare, and lean readiness assessment frameworks. The authors identified six main categories from a literature review (top management and leadership, human resources, patient relations, supplier relations, processes, and continuous improvement), and validated these based on experts’ opinion. Several factors were identified as crucial for EDs, including top management and leadership, human resources, patient relations, supplier relations, processes, and continuous improvement. The framework has not yet been tested, which prevents the author from declaring it fit for EDs. To the author’s knowledge, this is the first lean readiness assessment framework for EDs and one of the few lean readiness assessment frameworks in the literature.
    • Lean Readiness – The case of the European pharmaceutical manufacturing industry

      Garza-Reyes, Jose Arturo; Betsis, Ioannis, E.; Kumar, Vikas; AL-Shboul, Moh’d Anwer; University of Derby (Emerald, 2016-11)
      Purpose: The purpose of this paper is to assess the quality practices of European pharmaceutical manufacturers to determine the level of readiness of this industrial sector to implement and/or sustain lean manufacturing (LM) Design/methodology/approach: An assessment framework developed by Al‐Najem et al. (2013) was adapted to evaluate how ready European pharmaceutical manufacturers are to implement and/or sustain lean manufacturing. Therefore, the lean readiness (LR) level of these organisations was assessed through six quality practices related to LM. These included: processes; planning and control; human resources; top management and leadership; customer relations; and supplier relations. One research question and three hypotheses were formulated and tested using a combination of descriptive statistics and non-parametric Mann-Whitney test. Data was collected through a survey questionnaire distributed to 310 European pharmaceutical manufacturers and responded by 37 of these organisations. Findings: Overall, the results of this study indicate an inadequate level of LR for the participating firms. Simultaneously, it was concluded that factors such as company size, type of relationships with suppliers and ISO 9000 certification do not have an effect on the quality practices, and hence LR level, of European pharmaceutical manufacturing organisations Research limitations/implications: Practical implications: This study provides crucial information regarding the LR level of European pharmaceutical manufacturers, which can now be aware of the areas in their practices that require further improvement towards a successful lean journey. Simultaneously, organisations in the pharmaceutical sector that intend to implement LM can consider the results of this study and evaluate their readiness level. Managers can therefore refer to this research and use it as a platform to take better decisions regarding what quality aspects of their operations need to be enhanced to successfully deploy or sustain a lean strategy Originality/value: This research is one of the very few studies that have focused on evaluating whether the European pharmaceutical manufacturing industry is ready to successfully implement or sustain LM. Therefore, this research expands the limited existent body of knowledge of LM in this industry
    • Lean road transportation – a systematic method for the improvement of road transport operations

      Villarreal, Bernardo; Garza-Reyes, Jose Arturo; Kumar, Vikas; University of Derby (Taylor and Francis, 2016-03-07)
      Road transportation has become an important factor in international trade and the management of supply chains. However, this form of product logistics has generally been considered inefficient. Traditionally, practical inefficiencies of road transportation have been addressed through mathematical modelling, operations research-based methods and simulation. This paper presents an alternative systematic approach to improve road transport operations based on lean thinking and the reduction of the seven transportation extended wastes. To do this, the paper reviews the extant literature in the area of lean road transportation, providing a structured research definition of the application of lean thinking in road transport operations and hence guidance on the limited research conducted in this field. The systematic lean transportation method is then presented and empirically tested through a case study in a Mexican firm. The results obtained from the case study indicate that the proposed systematic lean method is an effective alternative for the improvement of road transport operations, with the number of distribution routes and distance travelled being reduced by 27 and 32%, respectively. The proposed method can be used by organisations as a guide to help them improve their road transport operations. In addition, the paper’s aim is to contribute by stimulating scholars to further study the application of lean thinking and waste reduction in road transport operations.
    • A lean six sigma framework for continuous and incremental improvement in the oil and gas sector

      Nascimento, D. L. M; Goncalvez Quelhas, O. L.; Gusmão Caiado, R. G.; Tortorella, Guilherme; Garza-Reyes, J. A.; Rocha-Lona, L., Muñoz-Sanchez, C., Garza-Reyes, J.A., Kumar, V., Lopez-Torres, G.C.; University of Derby; Federal Fluminense University, Rio de Janeiro, Brazil; University of Santa Catarina, Florianopolis, Brazil; Instituto Politecnico Nacional, ESCA Santo Tomas, Mexico City, Mexico (Emerald, 2019-09-19)
      This article aims to explore synergies between Lean Production (LP) and Six Sigma principles in order to propose a Lean Six Sigma (LSS) framework for continuous and incremental improvement in the oil and gas sector. The Three-Dimensional LSS Framework seeks to provide various combinations about the integration between LP principles, DMAIC cycle and PDCA cycle to support operations management needs. Design/methodology/approach - The research method is composed of two main steps: (i) diagnostic of current problems and proposition of a conceptual framework that qualitatively integrates synergistic aspects of LP and Six Sigma; and (ii) analysis of the application of the construct through semi-structured interviews with leaders from oil and gas companies to assess and validate the proposed framework. Findings - As a result, a conceptual framework of LSS is developed contemplating the integration of LP and Six Sigma and providing a systemic and holistic approach to problemsolving through continuous and incremental improvement in the oil and gas sector. Originality/value - This research is different from previous studies because it integrates LP principles, DMAIC and PDCA cycles into a unique framework that fulfils a specific need of oil and gas sector. It presents a customized LSS framework that guides wastes and costs reduction, while enhances quality and reduces process variability to elevate efficiency in operations management of this sector. The paper type is an original research that present new and original scientific findings.
    • A Lean Six Sigma Framework for the Reduction of Ship Loading Commercial Time in the Iron Ore Pelletising Industry

      Garza-Reyes, Jose Arturo; Al-Balushi, Mustafa; Antony, Jiju; Kumar, Vikas; University of Derby (Taylor&Francis, 2016-04)
      Evidence suggests that specifically designed frameworks to implement Lean Six Sigma (LSS) projects to tackle particular problems are more effective than “generic” versions. This paper proposes an implementation framework to effectively deploy LSS to improve a key operation and performance indicator, i.e. ship loading commercial time, of one of the largest world producer of iron ore. This article therefore contributes with a refined framework to effectively implement LSS, and documents its successful application and effectiveness within the context of the case organisation. The LSS framework and project contributed in helping the studied organisation to improve both the capability of its ship loading process and commercial time by more than 30 percent, resulting in operational savings in the range of $300,000 USD per year. The systematic nature of the framework proposed also helped the organisation to establish a standardise routine to improve its operations. Managerial implications exposing the challenges faced during the implementation of LSS are also discussed to serve as lessons learnt to be considered in other LSS projects. Managers and engineers in charge of improving operations and processes can benefit from this paper as it can be used as a guide to direct the conduction of LSS projects and the empirical application of its principles and tools.
    • Lean Six Sigma project selection in a manufacturing environment using hybrid methodology based on intuitionistic fuzzy MADM approach

      Singh, Mahipal; Rathi, Rajeev; Antony, Jiju; Garza-Reyes, Jose Arturo; Lovely Professional University, Phagwara, India; Heriot-Watt University, Edinburgh; University of Derby (IEEE, 2021-02-08)
      Project selection has a critical role in the successful execution of the lean six sigma (LSS) program in any industry. The poor selection of LSS projects leads to limited results and diminishes the credibility of LSS initiatives. For this reason, in this article, we propose a method for the assessment and effective selection of LSS projects. Intuitionistic fuzzy sets based on the weighted average were adopted for aggregating individual suggestions of decision makers. The weights of selection criteria were computed using entropy measures and the available projects are prioritized using the multi-attribute decision making approach, i.e., modified TOPSIS and VIKOR. The proposed methodology is validated through a case example of the LSS project selection in a manufacturing organization. The results of the case study reveal that out of eight LSS projects, the assembly section (A8) is the best LSS project. A8 is the ideal LSS project for swift gains and manufacturing sustainability. The robustness and reliability of the obtained results are checked through a sensitivity analysis. The proposed methodology will help manufacturing organizations in the selection of the best opportunities among complex situations, results in sustainable development. The engineering managers and LSS consultants can also adopt the proposed methodology for LSS project selections.
    • A lean thinking and simulation-based approach for the improvement of routing operations

      Villarreal, Bernardo; Garza-Reyes, Jose Arturo; Kumar, Vikas; University of Derby (Emerald, 2016)
      Purpose: The improvement of routing operations performance has been of great concern for organisations. This has led to the development of alternative lean-based methods, however the literature research on the applications of lean thinking in the transportation sector is still considered rather limited. Therefore, this paper presents a lean thinking and simulation-based approach to improve the efficiency of warehousing and routing operations. Design/Methodology/Approach: The paper reviews the existing literature in the area of lean transportation and then presents and applies a novel approach to improve the vehicle routing operations of a Mexican firm. The proposed approach suggests the classification of wastes into those relevant to transport operations, their identification through a Transportation Value Stream Mapping (TVSM) study, and the use of the Transportation Overall Vehicle Effectiveness (TOVE) index for the measure of the overall performance of the transport operations. Findings: The results obtained from the case study indicate that the proposed approach is an effective alternative for the improvement of vehicle routing operations as the number of routes decreased from 30 to 22 and the distance travelled by 32%. Similarly, the average number of clients served by each route increased by 23% as well as the TOVE index increased from 6.9% to 19.3%. The TOVE component measures of vehicle performance and operating availability efficiencies also increased significantly while quality issues, in the form of number of customers not served per route, were reduced from 6 to 0. Originality/value: The improvement of routing operations performance has been traditionally addressed through operations research and mathematical modelling approaches. This paper presents an alternative and novel lean thinking and simulation-based approach to improve the efficiency of routing operations.
    • A lean transportation approach for improving emergency medical operations.

      Villarreal, Bernardo; Garza-Reyes, Jose Arturo; Granda-Gutiérrez, Edgar; Kumar, Vikas; Lankenau-Delgado, Samantha; Universidad de Monterray; University of Derby; University of the West of England (Taylor and Francis, 2018-08-14)
      This paper extends the approach of Lean transportation to improve the performance of emergency medical processes (EMP) by adapting its main concepts into the main characteristics of the EMP environment. The paper is based on an inductive theory-building process initiated from a case study in the field of emergency medical services. The development of the suggested performance improvement approach triggered from an exhaustive analysis of a process involved and an exploratory review of the existing improvement approaches available. The process of concern can be described as a specialized transportation process, where human lives are at risk. Its characteristics led to a natural application of Lean transportation. The results include, a novel approach for improving the agility and efficient EMS processes. This is validated with an application for improving ambulance response times and turnaround times of the Red Cross operations located in Monterrey, Mexico. The approach proved to be an integrated scheme for identifying waste opportunities at a systems level. This characteristic is important to let operations management prioritize improvement efforts in a limited budget situation. This work suggests the application of the emerging Lean transportation approach for increasing the agility performance of EMS processes.
    • A lean transportation approach for reducing distribution cost: A case study

      Villarreal, Bernardo; Garza-Reyes, Jose Arturo; Ocañas, Priscila; Martinez, Fernanda; Universidad de Monterrey; University of Derby (IEEE, 2017-07)
      This work describes the strategy of a Mexican firm to improve its transportation cost of unused truck capacity. This is based on the application of a transportation waste elimination scheme for increasing efficiency in its warehousing and routing operations on a detailed level. The Operational Equipment Effectiveness index used in TPM is adapted to be used as the main performance measure. Availability, performance and quality wastes are identified using Value Stream Mapping of the distribution operations. The implementation of the improvement initiatives is still in progress but pilot test and projected results are provided.
