Study on the emergency capacity of coal mine enterprises in Longdong Area based on D-FAHP method

Abstract

Emergency capability assessment is a complex system with multiple factors, variables and levels. Based on this, a method combining D-number theory and fuzzy analytic Hierarchy process (FAHP) is proposed to study the emergency capacity of coal enterprises in Longdong area. Based on the limitation of D-S evidence theory, the D-number theory was optimized and improved. According to the principles of systematicness, feasibility, scientificity and timeliness, a hierarchical structure model of enterprise emergency capability assessment was constructed from the perspective of pre-incident, mid-incident and post-incident, which consisted indicators of 4 first-level and 18 second-level. Combined with the assessment results of experts, a quantitative analysis and evaluation of the emergency response capacity of a coal enterprise was conducted by using FAHP. The comprehensive score of the enterprise was 80.45, and the level of emergency response capacity was "good". The D-FAHP method has high reliability in evaluating the emergency response capability of coal enterprises, avoiding the impact of uncertain and incomplete information on the assessment results. This can effectively identify the weak links in emergency management and meet the needs of enterprises in emergency decision-making, which has important guiding significance for improving the ability and level of enterprises in emergency management.
