| 摘 要： | 在模糊集理论的基础上，通过建立评估指标集，求取各性能指标的隶属度函数和权重，建立了内燃机整机性能的模糊综合评估模型，并藉此对内燃机主要性能指标的加权模糊综合评估方法进行了研究，提出了定量化和解析化评估的方法，通过对多种内燃机的整机综合性能所进行的计算分析表明，内燃机整机性能模糊综合评估的关键是隶属度函数和权重的确定，而合理地确定各性能指标的主观赋权对评估结果有着十分重要的影响，实例计算结果验证了所建评估模型是切实可行的。

| Abstract: | A model of fuzzy evaluation of the performances of internal combustion engines is founded on the fuzzy collection theory and the subordinate degrees as well as the weight values are determined in relation with the performance parameters of the engines. By means of forming a set of evaluation indexes, a research of weighing fuzzy comprehensive evaluation of the main performances of the engines is hence carried out. Also a way of quantitative and analytical evaluation is put forward. The computation results show that the key to the comprehensive evaluation is the determination of the subordinate degrees and the weight values related to the engine performances, especially a reasonable consideration of subjectively given weight values which have much more important effects on the evaluation result. The model is verified to be practical and feasible by calculating the actual examples. |
