基于干扰模型的机群保障点失效应急重构策略生成方法

A Disruption Model based Emergent Reconfiguration Method for Aircraft Fleet Support Station Failure

舰机适配性设计中的航空保障系统对舰载机群进行使用保障和维修保障的过程中,由于舰船甲板空间不足、备件不足、机务人员不足等原因,导致直升机不能及时得到保障,将这些因素抽象为舰船上保障点不可用。通过考虑舰船上直升机群保障过程中的保障点失效情况,提出一种保障点失效应急重构策略生成方法。建立了保障点失效干扰模型,运用拉格朗日松弛法对模型中保障点数量约束进行松弛,采用次梯度优化算法求解拉格朗日对偶问题,并结合启发式算法给出保障点失效的应急调整方案。最后,以舰载直升机机群任务出动保障作为案例,验证了方法的有效性。

In order to solve the problem of mission oriented helicopter fleet support station failure, an emergent reconfiguration method was proposed, which was based on disruption model. Firstly, the response process of helicopter fleet to disruption was analyzed and then a support station failure model was established. Through the application of Lagrange relaxation algorithm, the quantity con- straints of support station were relaxed. A Lagrange heuristic algorithm was proposed, so as to gener- ate emergent reconfiguration scheme with support stations failure. Eventually, a fleet of 20 helicop- ters was studied for verification purposes. The result demonstrated that the proposed method could realize emergent reconfiguration of helicopter fleet support oriented to support stations failure.
