Fault Interaction Analysis with Extended FMEA Model using Cloud Model Theory and DEMATEL: A Novel Approach to Risk Assessment

Abstract

The failure mode and effect analysis (FMEA) is a method to identify and mitigate different problems in many manufacturing processes, its effectiveness is questionable unless it is more closely linked to solve difficult problems. In addition, the disruptions experienced in the production process are interrelated and cannot be considered independently of each other. Instead, they are intertwined, and without adequate attention to this relationship, research will reflect the accuracy of its conclusions. It is therefore important to determine not only the significance of the faults, but also the nature of the faults. This course includes the use of cloud modeling theory and the evaluation of decision-making experiments and test models to meet the needs of the business and overcome the limitations of traditional practices. Three contributions of this approach are: First, using Cloud Model Theory to solve the problem of random and uncertain decisions. Second, decision-making and trial evaluation laboratory (DEMATEL) has been extended to consider cloud model configuration to detect critical errors. Third, a case study is presented to demonstrate the advantages and effectiveness of the approach. The integration of Cloud Model Theory and DEMATEL reveals the novelty of this work by extending the failure model and related analysis, realizing its applicability in the system production process. This approach ensures that managers are aware of the biggest risk areas and take precautions in advance. As a result, losses resulting from negative effects are minimized and production processes become efficient and effective.
