“…"Resistance to change," "lack of top management commitment" and "lack of training to employees" are the most prominent barriers on the basis of their prominent score. Akrami et al (2020) facilitated the implementation of lean operations in organizations. The result showed that there are three clusters in 20 wastes.…”

Companies have been forced to find alternatives to balance productivity and the environment in their operations and products as they move to greener operations and products. The result of this action is the balancing of continuous or simultaneous exploration using pure and green designs. The purpose of this paper is to identify green-lean evaluation model in Automotive Industry. In this study, important criteria of green lean production system were identified from studies conducted in this field. The effects of the proposed criteria and their relationships are examined using a questionnaire. Furthermore, the Best-Worst Method (BWM) has been used for ranking a weight matrix. Also, the causal relationships among each criterion and sub-criteria are obtained by utilizing the Decision making trial and evaluation laboratory (DEMATEL) technique . The results showed that the use of environmental-friendly and recyclable packaging materials and the increase in the useful life of packaged materials ranked as top two in the Green-Lean in this realm. In operational management, the green lean techniques will be implemented to reduce both waste and pollution. Also, this strategy allows the company to enhance its operational and environmental efficiency.

“…Therefore, lean manufacturing can be taken as a successful organizational tool to implement in manufacturing organizations for continuous improvement. However, despite many benefits of lean manufacturing, it is difficult to be applied effectively in the manufacturing sector due to (i) imperfect understanding of the lean thinking concepts and the purpose of lean practices [7], (ii) misapplications due to the use of wrong lean tools to resolve a specific problem [8], (iii) the use of a single tool to solve many problems [9,10], and (iv) the implementation of the same set of solutions to provide the answer to each problem [11]. These limitations are needed to be tackled by top management, casting experts, lean experts, and all the employees of the organization.…”

Globalization breeds increasing competition. In today's dynamic climate, lean thinking has been found a promising business continuous improvement strategy for improving quality while reducing product cost and delivery time. However, its implementation has dynamic nature of challenges that varies from industry to industry and country to country, necessitating a specific framework by taking all stakeholders onboard. This study aims to propose a lean implementation framework to reduce defects and waste to improve the performance of the metal casting industry. The structure of the framework has been divided into three phases namely the lean conception phase, lean implementation phase, and lean sustainability phase. The proposed framework integrates the six sigma DMAIC methodology with lean tools and techniques to reduce defects and achieve performance improvement. A solid cast software has been used as a computer-assisted casting simulation tool to perform the analysis of defects within the casting. Further, the proposed framework is demonstrated and validated by employing a real-time case study that was manufactured using the sand casting process. The obtained results show remarkable improvements in poured metal weight (33.3%), mold weight including gating system (40%), casting yield (24.56%, rejection rate (90%), and financial saving (24.63%). As a result of analysis of percentage improvements data, the proposed framework can provide the practitioners with a standard roadmap and motivate the casting industries to implement lean for performance improvement through organizational change. Through the effective application of the lean implementation framework, quality enhancement has been demonstrated.
