发动机总体方案的模糊综合评价

Synthetic Fuzzy Evaluation of Design Scheme for Engine Total Systm

发动机总体方案评价是一个多目标评价问题。本文考虑到诸多评价因素的模糊性,提出了模糊综合评价方法,建立了模糊综合评价模型,并编制了应用程序,对国内外几种发动机进行了实例评价,从而证明了该方法作为一种定量分析手段的先进性和可靠性。

The scheme evaluation of engine total system is a multi - object problem. On account of fuzziness of many evaluated factors, this paper proposed a synthetic fuzzy method for evaluating engine design scheme and described the establishment of synthetic fuzzy model. Also, a practical evaluation example is given by using the corresponding program written by author. The results showed the advance and reliability of this method.
