工程技术问题常具有多种属性,故评价事物亦要兼顾多方面因素,尤其是在工程评价、生产规划、管理调度、教育管理等复杂系统中,欲作出任何决策,都必须对多个相关因素作综合考虑,而评判结果常是评判集上的一个模糊子集,有时还要分级考虑,这就是多级模糊综合评判问题。本文以对建筑工程的评价为例,探讨多级模糊综合评判方法的应用。 Engineering technology problems often have many attributes. Therefore, evaluating things must also take into account various factors, especially in complex systems such as engineering evaluation, production planning, management and dispatch, and education management. If you want to make any decision, you must have multiple related factors. Considering comprehensively, the judging result is often a fuzzy subset on the judging set, and sometimes it is considered hierarchically. This is a multi-level fuzzy comprehensive judging problem. This paper takes the evaluation of construction engineering as an example to discuss the application of multi-level fuzzy comprehensive evaluation method.
