基于图示评审技术的舰载机航空保障时间分析

Aircraft Support Process Time Analysis Based on Graphic Evaluation and Review Technique

为了解决舰载机航空保障活动逻辑关系和时间的不确定性问题,在对舰载机航空保障作业流程分析的基础上,建立了一种基于随机网络的保障流程模型。利用图示评审技术(GERT)对保障时间进行求解,并给出了求解步骤。结合案例验证了模型算法有效性和适用性。通过模型的灵敏度参数分析,提出了对航空保障作业的决策建议。

To deal with the uncertainty problem about the logical relationship and time of aircraft support activities, a support process model based on random network is built by analyzing the aircraft support operating process. The support operating time is solved by graphical evaluation and review technique （GERT） , and the solution steps are given. A support process example is studied to demonstrate the effectiveness and applicability of the proposed methodology. According to sensitivity parameter analysis, the corresponding suggestions on aircraft support operations are presented.
