基于模糊层次分析的合成氨装置安全现状评价

Comprehensive Evaluation of Safety State of Synthetic Ammonia Device Based on Fuzzy Analytic Hierarchy Process

以合成氨装置安全现状评价为目的,结合"人—机—环境—管理"系统思想将影响合成氨装置安全现状的因素,分为工艺条件、员工素质、设备安全可靠度、职业卫生和安全管理等5大类和21小类。运用模糊数学方法对层次分析法进行改进,确定各指标因素的权重,构建合成氨装置安全现状综合评价模型,并运用该模型对某合成氨装置安全现状进行综合评价。结果表明:该评价方法可以有效地对合成氨装置安全现状进行综合评价。

For comprehensively evaluating the safety state of Synthetic Ammonia Device, and according to the ＂ human - machine - environment - management＂ system thinking, the impact factors of the safety state of Synthet- ic Ammonia Device were measured by 5 major indicators, and 21 sub - indicators. Based on the method of fuzzy mathematics, the study of analytic hierarchy process （AHP） was improved, and the weight sets are determined. A comprehensive model for evaluating the safety state of Synthetic Ammonia Device is proposed, where the weight of each indicator is determinate based on FAHP. The actual case was evaluated using this model and the result show that this model is feasible for evaluating the safety state of Synthetic Ammonia Device.
