Vulnerability assessment of coal mine enterprise with the method of ascertaining weight based on analytic hierarchy process and rough set

Based on the description of the research,basic concepts and evaluation models of vulnerability,and assessment model of vulnerability was established, vulnerability assessment on the specific emergency management system of coal mine and specific indicators of the vulnerability assessment were listed.The weight of the first level indicators and the weight of the second indicators were determined by the use of the combination of weight method and the equal of weight method in the comprehensive consideration of subjective and objective factors,and then the vulnerability index was obtained.At last the vulnerability of mining and the size of specific indicators in the system vulnerability were analyzed.It can provide a new quantitative assessment method for the emergency capability assessment of coal mine enterprises and conducive to do a comprehensive grasp of emergency management.
