Integrated Sustainable Production Value Measurement Model Based on Lean and Six Sigma in Industry 4.0 Context
本文开发了一个结合精益六西格玛和德尔菲法的可持续生产价值测量模型，通过解释性结构建模量化质量要素与可持续性指标的关系，并在伊朗工业集群案例中验证，为管理者提供质量改进新视角。
Today's competitive environment requires a higher level of quality in processes, services, and products to reach a larger portion of market share and economic success. Quality management being a systematic approach for quality-related evaluation and development is substantial for companies. Industry 4.0 is defined as the integration of physical machinery systems with digital networking. Industry 4.0-related technologies provide extensive opportunities for quality-related issues by incorporating economic, environmental, and social impacts. To encompass all dimensions effective on quality management, it is necessary to process a large amount of data within the context of industry 4.0. Advanced production systems and quality management are complementary resources to enhance the functionality leading to a higher competitive advantage. This article develops a sustainable industry 4.0 production value measurement approach. The quality elements are collected and purified using the concept of lean six sigma and Delphi technique. Among all quality elements, those that are related to leanness and six sigma are extracted. Then, adapted interpretive structural modeling (AISM) is developed to map elements of lean six sigma and sustainability factors and indices. As a quantification method, sustainable production measurement relation is formulated. The process is implemented as a case study in an industrial cluster located in Iran. The results imply new aspects of quality improvement to the managers of the cluster.
