基于DEA的研制阶段装备保障方案评价模型

Evaluation model of materiel support plan in development phase based on DEA

针对目前研制阶段装备保障方案评价在角度和方法上的不足,提出基于数据包络分析(DEA,Data Envelopment Analysis)的评价模型.分析提炼保障系统的整体特性,建立保障系统的特性评价参数,构建基于数据包络分析的评价模型,通过计算保障方案的相对效率指数进行保障方案的评价,采用基于劣势前沿面的数据包络分析评价模型对多个有效保障方案进行二次评价,实现了保障方案的排序.结合研制阶段某型号军用飞机保障方案给出评价示例,从而验证了该模型的可行性和有效性,可为国防工业部门在研制阶段保障方案的评价上提供有效的决策支持.

To solve the problem that support plan evaluation existed many defects in angles and methods in the previous studies, the evaluation model based on data envelopment analysis （DEA） was presented. The support system general characteristics were abstracted, and evaluation parameters of support system charaeteristics were established. The model based on data envelopment analysis was established to calculate relative efficiency indexes for assessing support plans, and the evaluation model based on inferior frontier was used to reevaluate several effective support plans, and ranking of alternatives was realized. Evaluating certain type military aircraft support plans were given as an example, feasibility and validity of the model were verified. It could provide excellent decision supporting for defense industrial sections to evaluate materiel support plans in development phase.
