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.
In order to deal with the uncertain information existed in the process of purchasing fighter aircraft, the preference planning theory is first introduced into the procurement effectiveness evaluation.Firstly, the evaluation system of purchasing efficiency of fighter aircraft is established, and the uncertainty of indicators and preferences is expressed in the interval form, and the RICH method is used to solve the problem. Some attributes are only the ordinal information of alternatives, and are modeled by mixed integer programming.The model is integrated with preference programming via linear inequalities.Finally, the effectiveness of the proposed method in uncertain environment is verified by an example.
