针对影响因素复杂的总体评价问题,提出了一种多属性群决策方法。该方法通过模糊影响图构建多层决策模型,利用模糊关系矩阵传递专家的意见,利用证据理论集结专家意见。该决策方法利用属性间客观存在的模糊关系进行决策,不需要确定决策属性的权重。实例分析表明,本方法可行,有利于降低决策信息的不确定程度。 Aiming at the problem of complex evaluation of overall evaluation, a multi-attribute group decision-making method is proposed. The method builds a multi-layer decision-making model through the fuzzy influence diagram, uses the fuzzy relation matrix to transmit the opinions of the experts and uses the evidence theory to build up the opinions of the experts. The decision-making method makes use of objec- tive fuzzy relations between attributes to make decisions, without determining the weights of decision attributes. The case study shows that this method is feasible and helps to reduce the uncertainty of decision information.
