模糊多属性决策方法评价变压器状态维修策略

Assessment on Condition Based Maintenance Policy of Transformer Using Fuzzy Multiple Attribute Decision Making

提出了一种电力变压器状态维修决策的模糊多属性决策方法。通过综合分析 ,在兼顾安全性和经济性的基础上 ,选用维修所需技术水平、维修风险、维修对生产的影响、故障对安全的危害、综合费用以及维修效果 6个决策属性。通过对某一变压器状态维修方案的决策过程分析 ,采用模糊简单加权平均决策和模糊折衷决策 2种方法 ,具体探讨了模糊多属性决策方法在电力变压器状态维修决策中的应用 ,结果表明模糊多属性决策方法可行。

The fuzzy multiple attribute decision-making method to condition-based maintenance of transformer is proposed. By synthetically analyzing based on safety and economy, six decision attributes such as the needed technology level, maintenance risk, maintenance impact to production, the harm of fault to safety, integrated cost and maintenance effect are selected. Through analyzing the decision process of a certain condition-based maintenance of transformer using fuzzy simple weighted mean decision and fuzzy compromised decision methods, the detailed application of fuzzy multiple attribute decision-making method to condition-based maintenance of transformer is discussed. The conclusion proves that fuzzy multiple attribute decision-making method to condition-based maintenance of transformer is feasible.
