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 view of the shortcomings in the current research and development stage of equipment support scheme evaluation, this paper proposes an evaluation model based on stochastic frontier analysis (SFA). First of all, the characteristic of the refinement security system is analyzed. Based on this, the characteristic evaluation parameters of the security system are established, and then the evaluation model based on SFA is constructed. The security plan is evaluated by calculating the efficiency index of the plan, As well as the sensitivity analysis of evaluation indicators. Finally, an evaluation example is given based on a certain type of aircraft support plan during the development stage, and compared with DEA evaluation results, the evaluation results have high consistency, which verifies the feasibility and effectiveness of the model , Which can provide effective technical support for the research and development party to ensure the evaluation and decision-making of the scheme and improve the design during the research stage.
