摘要
针对柔性制造系统的设计问题,提出了用Petri网精细化操作解决问题的方案.给出了两种精细化操作.研究了Petri网精细化操作的动态性质保持问题,给出了精细化操作保持活性、有界性、可回复性的充分必要条件;对一个柔性制造系统进行了设计和验证.其结果可为Petri网系统静态和动态性质的考察提供有效途径,为Petri网复杂大系统的分析提供重要手段,并特别适合于柔性制造系统的设计,具有一定的实用价值.
A scheme is obtained by using some kinds of Petri net refinement, according to the design of flexible manufacturing system. Two kinds of refinement are obtained. Dynamic properties have been investigated. The sufficient and necessary conditions of liveness preservation, boundedness preservation and reversibility preservation are presented. A flexible manufacturing system has been designed and verified. These results are useful for studying the static and dynamic properties of Petri nets and analyzing properties of large complex system. The refinement method is especially fit for the design of flexible manufacturing system and practical to use in reality.
