配电网规划方案的综合决策对电网的发展建设和改造具有重要指导意义。运用层次分析法求解权重，基于对电网规划的柔性需求分析，引入区间数代替传统逼近理想解法中的点值进行改进，利用指标裕度体现待规划电网的实际情况，进一步采用基于度的区间数排序法分析所得结果，将方案进行优劣排序，据此为配电网规划问题决策出最适合的方案。实例计算表明，基于区间数的逼近理想解法体现了方案与问题的契合关系，提高了评价结果的准确性，具有较好的现实意义。
配電網規劃方案的綜閤決策對電網的髮展建設和改造具有重要指導意義。運用層次分析法求解權重，基于對電網規劃的柔性需求分析，引入區間數代替傳統逼近理想解法中的點值進行改進，利用指標裕度體現待規劃電網的實際情況，進一步採用基于度的區間數排序法分析所得結果，將方案進行優劣排序，據此為配電網規劃問題決策齣最適閤的方案。實例計算錶明，基于區間數的逼近理想解法體現瞭方案與問題的契閤關繫，提高瞭評價結果的準確性，具有較好的現實意義。

Comprehensive Decision-Making of Alternative Transmission Network Planning is important to rea-sonable grid construction and transformation.According to the drawback of the existing method of Compre-hensive decision-making of alternative transmission network planning,interval number and interval arithmetic were introduced.It calculated weights by Analytic Hierarchy Process (AHP),and instead interval numbers of point values to improve Technique for Order Preference by Similarity to Ideal Solution (TOPSIS),in which the requirements of the planning area were reflected by indicator margin based on analysis of the flexible require-ments of network planning,then adopted the NSG degree-based ranking method analyzing the results calculat-ed by improved TOPSIS and ranking the programs to choose the most appropriate scheme for planning prob-lem.At last,the example showed that TOPSIS based on interval numbers enhanced the accuracy and reliabili-ty with good practical significance.
