中文摘要：

为克服传统层次分析法（AHP）因采用固定不变的权重体系以及在此基础上的不因方案变化而变化的复合排序方法而不能反映复杂系统非线性、涌现性等本质特征的缺陷,在借鉴现有多目标变权决策方法变权思想的基础上,通过构建评价问题的新分析结构和方案评价的价值体系给出了一种关于方案优选排序的变权AHP实现方法,并对该方法的变权机理及其相对于传统AHP的优点予以了理论分析.实例应用表明,变权AHP方法具有较好的实际应用可行性.

英文摘要：

Traditional analytic hierarchy process（AHP） has the flaw of its fixed weights system（FWS） and the composite ranking approaches based on FWS,incapable of reflecting basic characteristics of complex evaluation issues,such as nonlinearity,emergence,etc.To overcome the above flaw,with the idea of weight varying（WV） adopted,a new alternative ranking approach based on variable weights is given by the way of constructing a new analysis structure of AHP evaluating problems and its corresponding value system for evaluating alternatives.The mechanism of WV in the new approach and its advantages over the traditional AHP are also analyzed.Applied to a real example,the approach is validated to be feasible and applicable.
