针对FMS的组成结构及控制特点 ,提出了一种层次递阶的统一建模方法。以面向对象建模技术和方法为主线 ,通过消息传递与驱动机制使各层递阶模型有机集成为统一的整体 ,并与实际系统中各个层次及其关系相对应 ,从而准确、方便地描述了FMS的规划设计、调度控制、运行及仿真等各个过程。
According to the compositional structure and control characteristics of FMS, a unified hierarchical modeling approach is proposed. With object-oriented modeling techniques and methods as the main line, the hierarchical model of each layer is organically integrated into a unified whole through message passing and driving mechanism, corresponding to each level in the actual system and its relationship, so as to accurately and conveniently describe FMS planning and design, scheduling control, operation and simulation of the various processes.
