基于Petri网/JavaBean的物流系统建模仿真技术

基于Petri网／JavaBean的分层有色Petri网(HCPN)物流系统建模，通过建立递阶层次、对象，子网和整个HCPN等模型，将其接入主Petri网(PN)，用颜色描述Petri网中流动的令牌．以汽车总装为例，将物流过程分解成若干子网和HCPN模型．并以HCPN仿真模型为核心，定义通用接口、建立与PN相应的模型组件．用户根据现场布局进行组态，通过拖放和连线建立模型间的联系构成HCPN仿真系统．

Modeling and Simulation of Physical Distribution System Using Petri Net and JavaBean

The model of Physical distribution system for Hierarchical Colored Petri Net(HCPN) based on Petri Net/JavaBean was established with modeling hierarchic, object, subnet and whole HCPN model, and Imbed them in host Petri Net (PN), tokens flowed in the PN was described with color. Take assembly of automobile as an example, the physical distribution course was resolved into several subnets and HCPN models. And regard HCPN model as the core, define the interface in common use and build the corresponding component with PN. The user carries on the configuration according to the on-the-spot overall arrangement, Set up the connection among models to form HCPN simulation system.
