基于规则约束着色Petri网(RCPN)的车间调度及Internet/Intranet环境下的系统开发

Workshop Scheduling Based on RCPN and System Development on Internet/Intranet

针对当前车间调度领域理论研究与实际应用之间的差距 ,在分析 Petri网在调度方面应用的基础上 ,根据实际应用的需要对其进行了适当的扩展 ,提出基于规则约束着色 Petri网 (RCPN)对车间加工系统进行建模 ,并通过所建立的模型对车间作业计划进行调度 .最后提出了一个可行的车间调度系统的框架设计和实现方案 ,利用 Java开发了基于Web数据库的 3层 B/ S/

In the paper, the gap between theoretic researches and practical application of workshop scheduling is analyzed. According to practical application requirements, traditional Petri Net is expanded and RCPN is put forward that is used to model workshop activities. Finally, a viable framework and scheme for workshop scheduling system is presented, and the scheduling system that adopts 3 layer B/S/D pattern is developed on Internet/Intranet by using Web database and Java.
