摘　　要：针对水轮机选型难以定量分析和评价的问题,提出基于模糊层次分析的选型方法。该方法首先采用层次分析得出各指标权重,其次应用模糊理论求得各指标的评价矩阵,最后将两者进行有机结合求出各机型的综合属性值,并以此为依据选择最优方案。实例计算表明该方法能够有效解决多因素影响的水轮机选型问题,具有良好的合理性和可靠性,为生产实践提供了理论依据。A method for selection of water turbine type based on fuzzy-AHP is put forward to overcome the difficulty in quantitative analysis and evaluation.In this method,the weights of all evaluation indices are calculated using AHP and index evaluation matrices are created with the fuzzy theory.Then these two methods are combined to establish integrated indices for all types of water turbines and make selection of the optimum type by comparison of these indices.Application indicates that this is an effective method in solving the selection problem involved with many factors and that the proposed method is reliable and practical.
