Risk hierarchical management and control model based on AHP-DEMATEL-cloud model

Abstract

In this paper, for the risk grading evaluation of China's coal mining enterprises, there are problems such as imperfect risk indicator system and subjectivity of evaluation results, etc. From the four elements of "human-machine-environment-pipe" safety production management, we construct a risk evaluation indicator system that meets the characteristics of mine safety production and construct a risk grading evaluation model based on AHP-DEMATEL-Cloud model. Based on AHP-DEMATEL-Cloud model, we construct a risk grading evaluation model. Taking a coal mining enterprise as the research object, the comprehensive risk assessment and grading application is carried out to obtain the risk level of the enterprise and the corresponding improvement opinions.
