采用安全分析法和专家调查法,以事故致因理论进行系统安全分析,建立了高校实验室压力容器使用管理系统的安全评价体系;应用层次分析法,确定了压力容器使用该评价体系中各子系统及各指标的权重;结合实际经验,根据安全规范构造各指标隶属度,进而根据评价集构造了隶属度函数,采用模糊综合评价法并得到各指标对评价集的最终隶属度、模糊矩阵和综合评价,求得压力容器使用管理系统安全状况的综合得分,进而划分安全评价等级,评价结论可为压力容器安全使用管理提供科学依据.%According to accident causation theory and on the basis of system safety analysis, an evaluation system for the safety of pressure vessel using management system of the laboratories in colleges and universities was built by using safety analysis method. By using analytic hierarchy process(AHP), the weights of subsystem and index of multiple evaluation system were determined. Combined with practical experience, the membership degree of each index was firstly constructed in the light of safety norms, then, based on the evaluation set, trapezoidal distribution membership function was constructed, and the ultimate membership degree, fuzzy matrix and the comprehensive evaluation of index for the evaluation set were achieved by using fuzzy comprehensive evaluation method. At last, the integrated score for the safety of pressure vessel using management system was attained, the safety evaluation rating was divided, and the disposal measures were put forward for each rating. The evaluation conclusion could provide scientific criteria for the pressure vessel safe using management.
