在分析维修设备保障流程建模与仿真重要性的基础上,分析了GERTS模型和广义Petri网(GSPN)模型在流程仿真中的应用特点,提出了基于嵌入式广义Petri资源约束网的GERTS仿真模型,并给出了具体的仿真算法.嵌入GSPN约束网的GERTS仿真模型,解决了GERTS难以对具有较强资源依赖性的过程很好描述的缺陷,可用于大型设备维修流程的仿真建模分析.最后,文章针对某部队对武器装备保障流程进行了建模和仿真实例分析,得出了资源配置的最优组合.并应用MATLAB对仿真结果进行了曲线拟合分析.

A GERTS Simulation Model Embedded with General Stochastic Petri-Net Support

Based on analysing the essentiality of maintenance guarantee process simulation,this paper presents a GERTS simulation model embedded with General Stochastic Petri-Net(GSPN) after analyzing the application of GERTS and GSPN model in process simulation,and gives its simulation algorithm.Embedded with GSPN,the model would discard the GERTS's inability in describing an action that depends more on the resource.The model is applicable to the simulation and analysis of complex processes of huge facilities.Finally,the paper probes into the example of the maintenance guarantee process of military facilities with the graphics of MATLAB and works out the optimum conclusion.
