摘要： 变压器维修策略的决策是一种涉及到量化指标和定性分析指标共存的混合多属性指标的决策问题.运用模糊理想解法(fuzzy TOPSIS)建立了变压器维修策略的模糊综合评价分析模型，来解决含有混合多属性指标决策问题.这种方法不仅可以对多台变压器的运行情况进行监视，通过利用计算相对贴近度来确定变压器的运行状态，进而确定变压器的维修策略，而且还可以通过专家系统对1台变压器的多种维修策略进行直接的判断与确定，通过精确的实数型指标值、区间数型的指标值和模糊数的指标值进行分类判断，给出多种维修策略下的取值情况，进而分析比较各个相对贴近度的大小，做出排序，决定选取哪种维修策略.通过实例验证此方法具有良好的决策效果.

Abstract: Transformer maintenance strategy decision is a decision-making problem of hybrid multiple attribute index related to coexistence of quantitative indicators and qualitative indexes. The fuzzy comprehensive evaluation analysis model of the transformer maintenance strategy was set up by using fuzzy TOPSIS， and the decision-making problem of hybrid multiple attribute index was solved. Through calculating the relative closeness degree to determine the transformers operation status， the transformer maintenance strategy could be determined by using the proposed method. In addition， the proposed method not only can monitor transformers operation status，but also can directly determine the best one from various maintenance strategy for a transformer using the expert system . The index values of accurate real type， interval type and fuzzy number were classed and judged， then the relative closeness degree of various maintenance strategy was sorted through analysis and comparison， based on which it could be decided to choose which kind of maintenance strategy. The result of the example shows that the method has good effect on transformer maintenance strategy decision.

Key words: power transformer, fuzzy TOPSIS, hybrid multiple attribute decision making, maintenance strategy, decision-making
