给出了基于模糊数的工艺方案模糊综合评价模型，详细介绍了模型中的加工质量评价的语言变量描述、模糊数表示、加工质量评价的综合处理、定量指标的模糊化处理、模糊数的排序等方法．给出了一个评价实例，所提出的方法不仅实用，而且适于建立基于 Ｗｅｂ的工艺方案评价系统．
The fuzzy comprehensive evaluation model of process scheme based on fuzzy numbers is given. The linguistic variables description, fuzzy number representation, comprehensive evaluation of processing quality evaluation, fuzzy processing of quantitative indexes, sorting of fuzzy numbers Other methods. An evaluation example is given. The proposed method is not only practical, but also suitable for establishing a web-based evaluation system of process scheme.
