摘要
在已有的定性演算的基础上,引入了定性值集上的定性关系,讨论了定性关系的基本性质,并定义了定性关系的并、交、差及复合运算.在文后给出了定性综合评判的3个基本要素,着重给出了主因素决定型定性综合评判的步骤,并将其应用到具体的实例中.
introduced t some operat composition established Based on the existing qualitative mathematical calculations in relevant reference, we he definition of the qualitative relations, investigated its basic properties and defined ors over the set of qualitative relations, such as union, intersection, difference, and operators. Finally, we gave three basis of qualitative synthetic evaluation, and measures of qualitative synthetic evaluation controlled by principal factor. At the same time, we applied the such measures to practice issue
