摘要
为解决绿色设计中材料选择的不确定多属性决策问题,提出一种基于集对分析的多属性决策模型。该模型应用联系数来描述材料选择方案之间的确定性与不确定性关系,分别在相对确定与不确定条件下,利用相对贴近度对方案进行综合排序,利用联系数的差异度对排序结果进行稳定性分析,并给出保持结果稳定的差异度系数取值区间的计算方法。并通过一个实例,应用该模型综合考虑材料的物理属性、经济属性和环境属性进行决策。分析结果表明,该模型是求解绿色设计材料选择不确定多属性决策问题的一种有效方法。
To solve the uncertain multi-attribute decision making problems of material s.election in green design, a model based on set pair analysis was presented. The connection number was used to describe the relation between certainty and uncertainty of alternative materials. The ranking of decisions was determined according to the relative approach degree and the reliability of the ranking result was analyzed by the discrepancy degree of the connection number in the condition of certainty and uncertainty respectively. The calculation method of value range of the discrepancy degree was put forward to maintain the resuh＇s stability. An example was solved with comprehensive evaluation on physical properties, economic and environmental properties of materials. As shown in the case study, the proposed model is an effective tool to solve the uncertain multi-attribute decision making problems of material selection in green design.
