基于SFA的研制阶段装备保障方案评价模型

SFA-based Evaluation Model of Materiel Support Plan in Product Development Phase

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,提出基于随机前沿分析(SFA)的评价模型。首先,分析提炼保障系统的特性,在此基础上,建立保障系统的特性评价参数,然后构建基于SFA的评价模型,通过计算保障方案的效率指数进行保障方案的评价,实现了保障方案的排序,以及评价指标的灵敏度分析。最后,结合研制阶段某型号飞机保障方案给出评价示例,并与数据包络分析(DEA)评价结果进行对比分析,评价结果具有较高的一致性,从而验证了该模型的可行性和有效性,可为研制方在研制阶段保障方案的评价决策和改进设计提供有效的技术支持。

In order to solve the problem that there exist many drawbacks in support plan evaluation in terms of approaches and methods in previous studies,this article presents an evaluation model based on stochastic frontier analysis（SFA）.First,support system characteristics are abstracted,based on which the evaluation parameters of support system characteristics are established.Second,a model based on SFA is established to calculate support efficiency indexes for assessing the support plan,and the ranking of alternative support plans is realized.In addition,the sensitivity analysis of evaluation indexes is made.Finally,evaluating a certain type of aircraft support plan is performed as an example.The two evaluation results of the data envelopment analysis（DEA）model and the SFA model demonstrate high consistency according to a comparative analysis of evaluation results.Thus,the feasibility and validity of the evaluation model based on SFA are established.This model can provide excellent decision support for evaluating and improving support plans in the product development phase.
