基于Arena的通信装备备件保障流程建模与仿真

Modeling and Simulation of Communication Equipments Spare Parts Support System Based on Arena

通信装备备件保障系统的复杂性决定了运用建模仿真技术对其性能研究的适用性及有效性。针对两级备件保障体制下备件配置问题,在分析通信装备备件保障流程的基础上,以备件利用率及故障装备修复率为输出指标,利用Arena仿真软件建立了基于流程的通信装备备件保障系统仿真模型。通过仿真实例,分析了不同备件配置策略对备件利用率及故障装备修复率的影响规律,仿真结果验证了模型的有效性,同时也表明:相比传统建模方法,在描述备件保障过程中变量的随机特性及系统的动态行为方面,Arena软件有显著的有效性和优越性。

Because of the complexity of the communication equipment spare part support system, the use of technique of modeling and simulation is applicable and effective in the study of the system performance. Aimed at the scheme of spare part under two - grade support system, based on the analysis of flow for communication equipment spare part support system and regarding the spare part utilization and restoring rate as indexes, the flow simulation model of spare part support system is built by Arena. The law affecting the spare part utilization rate and restoring rate under two - grade maintenance support by the connection spare part configuration policy is analyzed through ex- ample simulation, which verifies the effectiveness of the model. Simultaneously, in the course of analyzing and describing the stochastic characteristics of variable and the dynamic process of the system, Arena is more effective and superior than the traditional modeling methods.
