空调冷源设备的Fuzzy多级综合评判

Multi-Stage Fuzzy Synthetic Evaluation of Refrigeration Equipment in Air Condition

以模糊数学为理论依据，将空调冷源设备的综合性能和经济效益全面考虑，建立了制冷机的二级综合评判数学模型．该模型将因素集中的９ 个因素按初投资、运行费用以及安全环保运输分割成３ 个子集 Ｕ１， Ｕ２， Ｕ３ ，然后按一级评判得出其单因素评判矩阵 Ｒ１ ， Ｒ２ ， Ｒ３ ，给出３ 个子集 Ｕ１ ， Ｕ２ ， Ｕ３ 的权重分配，进行二级综合评判，得出最佳设备，并给出应用实例，实例计算表明。

A two-stage fuzzy synthetic evaluation mathematical method is proposed in this article,which is based on the fuzzy mathematics theory and the comprehensive consideration of the overall property and the economic benefits.In this method,nine factors in factor set are classified as three subsets (U 1,U 2,U 3) according to three angles which are initial investment,motion expenses,safety and environment protection and transportation.Then three singly-factor evaluation matrixes (R 1,R 2,R 3) are drawn according to one-stage evaluation.If the weighted distribution of three subsets (U 1,U 2,U 3) are presented,the best equipment can be drawn.An application example of the method is given and the theoretical results and the practical one drawn from the application example are totally the same .
