摘要: 针对工程实际中普遍存在的使用保障活动与维修保障活动并发这种典型的复杂情况,以基本作战单元为研究对象,基于排队论建立了保障设备满足率预计模型。基于产品的保障过程,分析了产品批送修数量的影响因素及确定方法,解决了非单件送修策略下保障设备满足率的预计问题。根据保障活动并发性及其发生频率的特点,通过分析产品批量到达的影响因素,给出了产品平均到达率和保障设备平均保障速率的确定方法以及产品批送修量的分布概率,进而给出了保障设备满足率的求解方法。通过算例验证了该模型和方法的有效性。

Abstract: Aiming at the concurrency of the operation support activities and the maintenance support activities, the estimation model of support equipment fill rate was developed based on the queue theory, in which basic combat unit was the research object. Influencing factors of batch size and its determination method were analyzed based on the support process, and the estimation problem of the support equipment fill rate was solved under the condition of non-single unit by one replenishing sending policy. Furthermore, on the basis of the influencing factors, the mean arrival rate of the items and the mean support rate of the support equipment, their determination method and the distribution probability of each batch size, were obtained according to the concurrency of the support activities and the characteristics of their occurrence frequency. Thereby, the solution method of the support equipment fill rate was proposed. Finally, the effectiveness of the proposed model and method was verified by a case study.

Key words: support equipment, queue theory, fill rate, batch size, mean arrival rate, mean support rate
