摘　　要：为明确大型舰船飞行甲板弹射器数量设计的理论依据,从调运指挥官的角度提出了"虚拟队列"概念,分析了其工作特点,对其工作模式进行了排队论建模。同时分析、建立了舰载机在弹射等待过程中的真实排队模型。忽略其它甲板因素的影响,基于排队论假设代入数值计算了不同弹射器数量对虚拟队列中舰载机的等待队长、系统等待耗时等关键指标的影响,使弹射器数量影响下的大型舰船舰载机出动能力得到了量化比较。计算结果表明,在给定条件下,甲板弹射器数量的增加能有效减少大型舰船舰载机出动时的排队等待现象,但在弹射器数量超过4部以后,这种良性影响将逐渐减弱。通过算例结论,验证了将排队论应用于大型舰船弹射器数量论证与设计的可行性。The objective of this article is to establish a theoretical basis for determining the quantity of catapult on the flight deck of large ship.As for investigation,the approach of ＂dummy queue（virtual queue）＂ was presented from the view of aircraft handling officer,and the task flow model was set up and analysis was carried out by using the queuing theory.The realistic model of task flow of carrier-based aircraft in standby position for launch was also constructed.A multiple calculations were conducted for the key targets,ignoring all the other factors,with regard to the influence of different quantities of catapults on the virtual length of aircraft＇s waiting queue and time of the system standby based on the assumption of the queuing theory.The results enable to have a quantifying comparison of sortie generation capacities of carried-based aircraft on the flight deck.The calculations also showed that under a given set of conditions,increasing the quantity of the catapult can obviously minimize the queuing length of the birds waiting in a queue for launch on the flight deck,but,if the number of catapult was greater than four,this would be less effective.Through the calculating results,application of the queuing theory to the demonstration as well as quantity design of catapult on large ship is proved to be practicable.
