Research On Gas Station Safety Evaluation Based On Grey System Theory Method

Gas stations operating oil with flammable and explosive,toxic and other characteristics,whether the surrounding environment or to the station staff are potential sources of danger,coupled with the recent years,China's oil retail industry rapid development,the number of gas stations continue to increase this further increase the potential danger to the reality of the possibility of accident conversion.Therefore,it is very important to study systematic and repeatable safety evaluation methods.The grey system theory method is a kind of method to study the uncertain system,this paper applies the method synthetically to the research of the safety evaluation of gas station,and realizes the satisfactory evaluation result.Firstly,in the condition of defining the relationship of safety factors,the grey relational analysis method is used to determine the weight of the evaluation elements.Then,based on the risk identification of gas station,the expert opinion and the grey clustering statistic method are used to determine the evaluation index of the safety factor of the gas station Gen.According to the inspection data of the actual project of the gas station,the safety grade of the gas station is evaluated by using the improved grey clustering decision method.It is proved that the evaluation conclusion is in accordance with the actual situation of the object and has high accuracy.
