燃气轮机性能评价的模糊综合评判方法

针对目前燃气轮机性能评价研究一般仅局限于某一方面，不能全面反应燃气轮机系统性能问题，该文提出了利用模糊数学理论，从技术经济、功能设置、可靠性及维修性4个方面来综合评判燃气轮机系统性能的新方法。文中分析过程给出的为二阶模糊综合评判，具体应用时，阶数可根据实际情况有所增减，同时权重系数及模糊评判矩阵的确定应综合各方面意见。模糊综合评判方法不仅适用于系统性能多因素评判，而且适用于组成系统的单体设备的多因素或单因素性能评判。

FUZZY COMPREHENSIVE METHOD FOR GAS TURBIINE EVALUATION

Currently to analyses the performance of a gas turbine is limited in a certain aspect, but not the unit a whole. Based on the theory of fuzzy mathematics, the paper puts forward a method for evaluating the gas turbine performance comprehensively from four aspects, namely from technical economy, function capability, reliability and maintainability. The analysis gives a second order fuzzy comprehensive evaluation. The order of fuzziness can be changed according to the specific cases. Meanwhile, the weight and fuzzy evaluating matrices should also be determined by a consideration of every aspect. This new method is applicable not only for multi-factor evaluation of system performance, but also for a mono-or multi- factor evaluation of unit performance for system.
