基于GERT网络的航空产品故障件返修流程研究

本文运用随机网络理论对航空产品故障件返修流程进行研究。明确了航空产品故障件返修流程,指出返修流程中多种不确定因素。运用随机网络理论,构建了航空产品故障件返修流程GERT网络模型,给出模型求解方法。结合某航空产品返修流程,得到产品返修合格概率,产品返修周期及方差,为领导层决策提供了科学依据。在此基础上,进一步对航空产品故障件返修流程进行了剖析,提出流程优化的具体方法。

Analysis on Invalid Parts Repair Process of Aviation Products Based on GERT

This paper uses the random network theory to analysis on invalid parts repair process of aviation products.With understanding of invalid parts repair process of aviation products,we point various of uncertain factors in the repair process.By using the random network theory,we construct a GERT network model to describe invalid parts repair process of aviation products and offer a way to solve the model.Based on a case of aviation products repair process,we get the probability,cycle time and variance of successful product repairing,these could be the useful results for leaders’decision.Based on above studies,we finally make some further analysis on invalid parts repair process of aviation products and provide some effective ways to optimize the repair process.
