摘　　要：应用基于熵权和改进的AHP法确定各属性的权重 ,以相对优属度代替绝对隶属度 ,最后进行模糊综合评判得出有限可行方案中的最优方案 .最后实例证明对于多属性决策问题 ,此法不失为一种切实可行的方法 .The weights related to the criteria are determined by ameliorative analytic hierarchy process (AHP) combined with entropy weights. It takes relative membership grade instead of absolute membership grade,and ranks alternatives by comprehensive evaluation. Finally, an example is given, which proves the method provided is feasible in multiple attribute decision.
