不确定环境下战斗机采购效能评估模型

为了处理采购战斗机过程中存在的不确定信息, 首次将偏好规划理论引入到采购效能评估中. 先建立战斗机采购效能评估体系, 指标和偏好的不确定性用区间形式表示, 求解采用RICH法; 针对一些属性只有备选方案的序数信息的情况, 采用混合整数规划进行建模. 模型通过线性不等式与偏好规划方法进行集成. 最后, 通过实例验算表明该方法在不确定环境下的有效性.

Procurement effectiveness evaluation model for combat aircraft under uncertainty

In order to deal with uncertain information in process of purchasing the combat aircrafts, the theory of preference programming is first introduced into procurement effectiveness model. An index system is proposed, which is based on procurement effectiveness evaluation for combat aircrafts, and the interval is using to present the uncertainty of the index data and the preferences. The best alternative is obtained by solving multi-criteria decision problem with a RICH approach. Considering ordinal information about alternatives in some attributes, the mixed integer linear programming is used to present it. The mixed integer linear programming is combined with preference programming methods by linear inequalities. Last, the model is verified by using an example under uncertainty.
