Identification of Key Brittleness Factors for the Lean–Green Manufacturing System in a Manufacturing Company in the Context of Industry 4.0, Based on the DEMATEL-ISM-MICMAC Method

In the context of Industry 4.0, lean–green manufacturing system has brought many advantages and challenges to industrial participants. Security is one main encountered in new environment, because smart factory applications can easily expose vulnerability threaten operational security whole system. It difficult address problem brittleness factor systems. Therefore, building on theory, this study proposes a index for systems company 4.0. The four dimensions: human factors, equipment environmental other factors. Decision-Making Trial Evaluation Laboratory (DEMATEL) approach was used calculate degree influence, being influenced, centrality causes causal relationships key influences between factors were identified. Then, dependence hierarchy each influencing analyzed using Matrix-Based Cross-Impact Multiplication Applied Classification (MICMAC) Interpretative Structural Model (ISM) methods, hierarchical structural model constructed. Finally, an intelligent that produces micro-acoustic material device as example verify accuracy proposed method. results show method not only identifies but also provide guarantee safe operation This provides theoretical guidance effective management systems; moreover, it lays foundation methodology assessing
