DEDS理论在CIMS中应用研究回顾与展望

离散事件动态系统ＤＥＤＳ理论为制造系统分析设计提供了支持工具，制造技术的发展又为ＤＥＤＳ理论提供了实际应用背景．本文综述离散事件动态系统ＤＥＤＳ理论的发展及其在计算机集成制造系统ＣＩＭＳ中的应用研究．分析了各种ＤＥＤＳ方法的特点和探讨了相应ＤＥＤＳ模型的描述范围．扼要叙述了ＣＩＭＳ的发展状况．阐述了ＣＩＭＳ新阶段对未来ＤＥＤＳ理论研究的要求。

The DEDS methodology has provided efficient tools for modelling, analysis and planning of manufacturing systems. In return, manufacturing practices have also provided real-life application environments for DEDS methodology. This paper summarizes the research efforts on DEDS methodology and its applications in CIM systems. Features of DEDS methods are studied and the application scopes of the related DEDS models are further discussed. Finally, the development tendencies of CIMS are briefly introduced, the requirements for future DEDS research imposed by CIMS evolutions are addressed.
