基于集对分析同一度的采空区处理方案研究

Evaluation of the Alternatives for Mined-out Area Disposal Based on the Identical Degree of Set Pair Analysis

针对采空区处理方案综合评价中各指标的不相容性,选用安全性(安全系数)、可行性、费用、需要时间等指标,利用集对分析方法,将评价采空区处理方案的多个指标合成为一个与最优评价集的相对贴近度,用来描述采空区处理方案的综合效益。以可供选择的5种处理方案为例进行了评价,得到综合效益最优的方案。研究结果表明:该方法评价结果与模糊优选法有较好的一致性,为采空区处理方案综合评价提供了一种新思路。

In view of the incompatibility of indexes in the comprehensive evaluation of alternatives for mined-out area disposal, the indexes such as safety （safety coefficient）, feasibility, cost and required time were combined, by the set pair analysis method, into a relative closeness degree of optimal evaluation sets for describing the comprehensive benefits of mined-out area disposal plans. A scheme with best comprehensive benefit was obtained from five alternatives by the evaluation. It is shown that the result of the evaluation by set pair analysis is well consistent with that by fuzzy optimization method, presenting a new way for the comprehensive evaluation of mined-out area disposal.
