现场维修保障下的编队装备系统多任务可靠度

Phased mission reliability for fleet equipment system under the maintenance support

装备系统可靠度是编队任务成功与否的关键因素之一,根据海上编队装备保障及多阶段任务的特点,对任务过程进行描述,提出一种维修保障策略。推导出基于排队理论的装备维修保障计算公式,建立了基于现场维修条件下装备系统的多阶段任务可靠度模型并对求解过程进行分析,最后通过实例给出系统任务可靠度的计算结果。根据仿真计算结果可知,随队配备维修分队可以在一定程度上提高装备任务可靠度,为实际工作中如何合理分配维修资源提供理论依据。

Equipment system reliability is one of the most critical factors for the success of naval ship formation＇s mission.According to the characteristics of ship formation＇s equipment support on the sea and phased mission,the process of mission is described,based on which a maintenance support policy is proposed.According to the queueing theory,the formula of equipment repairing probability is deduced,and the phased mission reliability model for equipment system under the maintenance support is established.After analyzing the process of calculation,the phased mission reliability for equipment system is calculated in a given example.The simulation result shows that the disposition of repair element can improve the mission reliability in a certain extent,which provides theoretical bases for how to allocate the maintenance resource reasonably in practice.
