摘　　要：为进一步分析现有决策方案中存在的问题,提出解决混合测度决策问题的优势度决策法。根据实际决策情况给出一组优势相关的定义,对优势度求取方法进行改进,对其互补性和一致性进行有效性验证。对改进方法的排序向量、优势向量以及比较向量的特征进行研究,与线性加权法和理想点法做对比分析,分析结果表明,该方法计算量小、精确性高、通用性好。实例分析结果表明了改进优势度算法的有效性。A dominance decision making method was proposed to solve mixed measure decision problems from decision-making plans.A group of definitions on dominance were given,the formula of computing dominance was improved,and the good complementarity and consistency owned by the dominance matrix were testified.The sorting methods among alternatives and their characteristics respectively from three aspects of sorting vector,dominance vector and comparing vector were studied.A contrast analysis between the proposed method and those such as linear weighting methods,ideal point methods were carried out.The method has less computational complexity in conjunction with better accuracy and compatibility.One illustrative numerical example shows the effectiveness of the dominance method.
