【摘要】 引入灰色系统理论,对传统理想解法(TOPSIS)进行了拓展,提出了一种基于组合权重的灰色关联理想解法(GC-TOPSIS)。利用AHP和熵值法对决策指标进行组合赋权,依据灰色关联分析理论,以灰色关联度为决策单元构造GC-TOPSIS模型,最后通过一个供应商选择的实例验证了方法的有效性和可行性。更多还原

【Abstract】 Introducing the Grey system theory,this paper presents a new Grey correlation technique for order preference by similarity to ideal solution(GC-TOPSIS) and so as to develop the traditional TOPSIS.First,we decide the weight of every decision-making index by using AHP and entropy method. Second,according to Grey correlation analysis method,we establish GC-TOPSIS by using Grey correlation degree as decision-making unit.Finally,through a supplier selection problem we prove its validity and feasibility.更多还原
