Abstract: The DEMATEL algorithm is an algorithm for analyzing the relationship between the influencing factors of complex systems. The algorithm has important application value for identifying the key factors of complex security system. First, on the basis of the DEMATEL algorithm, according to the knowledge of cognitive psychology and the status quo of the safety management of a gas station, the complex gas station safety system is divided into 4 subsystems, and further refined into 31 specific factors. Secondly, according to the DEMATEL algorithm, the MATLAB program is compiled to divide the cause factors and the result factors, and the influence degree, cause degree and center degree of each factor are calculated. Finally, the location of the key factors are displayed intuitively by drawing the cause results diagram. The results show that the information channel interruption, lack of recognition and information uncertainty, contingency plans and response defects are the key factors affecting the safety of gas stations. The longterm solution for gas station safety management is to control these 4 factors.

摘要: DEMATEL算法是一种分析复杂系统影响因素相互关系的算法,对识别复杂安全系统关键因素具有重要的应用价值。首先,在简述DEMATEL算法的基础上,依据认知心理学的知识和某加油站安全管理现状,把复杂的加油站安全系统划分为4个子系统,并进一步细化为31个具体因素;然后,依据DEMATEL算法编制MATLAB程序,划分出原因因素、结果因素,并计算各因素的影响度、原因度、中心度;最后,通过绘制的原因结果图找出关键因素的位置。结果表明,信息通道中断、认知缺乏、信息不确定性、事故应急预案及响应缺陷是影响加油站安全的关键因素,加油站安全管理的长久之计是控制好这4个因素。
