基于Petri网和BOM的拆卸建模方法研究

Disassembly Model Based on Petri Net and BOM

基于Petri网理论提出了虚拟拆卸网模型,关键技术是同步器对变迁的逻辑关系的确定.给出了其库所、变迁以及托肯的含义.基于基本对象模型提出了虚拟拆卸交互模型VDIM,研究了从网到VDIM的实体类型、事件类型、交互模式以及状态机的映射原理,并讨论了VDIM的模型可组合性.从联邦成员的划分,时间管理和同步管理三个方面研究了网模型和VDIM模型中仿真信息的融合,以便直接用于仿真系统的开发.最后的实例证明了研究的可行性.

Virtual disassembly net model is proposed based on Petri net,where the key is to decide the logical relationships of transitions by synchronizer.The meanings of place,transition and token are given.Virtual Disassembly Interoperable Model（VDIM） is proposed based on Base Object Model.The maps from the net model to VDIM′s entity types,event types,pattern of interplay and state machine are also studied.The fused information including federation division,time management and synchronize management are then researched,which could be used in the developing of simulations.The example proves the feasibility of the research.
