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

Abstract

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

DEMATEL, AISM, and MICMAC-Based Research on Causative Factors of Self-Build Housing Fire Accidents in Rural Areas of China

“…Driving force is the influence of one factor on other factors, and dependence is the degree of the influence of one factor over another [26]. According to Equation (10), the driving force value Q and the dependency value P of each factor were calculated from the reachable matrix R. According to the driving force and dependency values, causative factors could be divided into four categories, namely linkage, dependency, autonomous, and independent factors [27]:…”

Identification of Key Factors for the Development of Agricultural Biogas Plants in Poland

“…The choice of this method was made based on the analysis of the availability of methods enabling the identification of key factors in the case of including imperfect information about them, which we deal with in the practice of making contemporary decisions. Ultimately, three such tools were identified, namely MicMac, Interpretative Structural Modeling (ISM) and DEMATEL [62][63][64][65][66][67][68][69][70]. The universal nature of these methods means that, despite their considerable age, they are still willingly used by researchers.…”
