摘　　要：为实现产品全生命周期绿色设计方案的生成与决策,构建了基于功能-行为-结构-材料-工艺(FBS-MP)的设计方案多层级表达模型,并将绿色设计方案的生成转化为基于设计约束的约束满足问题(Constraint satisfaction problem, CSP)。进一步提出基于回溯算法的设计方案多层逐级求解策略,获得产品设计方案解集。同时,提出基于“组合赋权-逼近理想解排序(TOPSIS)-灰色关联分析(GRA)”的多属性决策方法,采用层次分析法与熵值法的主、客观权重进行非线性乘法加成,完成了评价指标的组合权重配置。通过在TOPSIS法分析中引入灰色关联度,实现了绿色设计方案的优选。最后,通过对多属性决策方法偏好系数与评价指标权重的敏感性分析,验证了所提方法的准确性与可靠性。In order to realize the generation and decision-making of product green design solution,a multi-layer expression model based on Function-Behavior-Structure-Material-Process(FBS-MP)is constructed,and the generation of green design solution is mapped to the constraint satisfaction problem(CSP).A stepwise solution strategy based on backtracking algorithm is proposed to obtain the design solution set.Moreover,a multi-attribute decision-making method based on“combination weighting-TOPSIS-grey relation analysis(GRA)”is proposed.The combined weights of evaluation indexes are allocated by nonlinear multiplication and addition of the principal and objective weights of AHP and entropy method.Furthermore,the optimization of green design solution is realized by introducing grey relation degree into TOPSIS analysis.Finally,through the sensitivity analysis of the preference coefficient and evaluation index weight of multi-attribute decision-making method,the accuracy and reliability of the proposed decision-making mechanism are verified.
