A Study on A Modeling Method for Life-Cycle Support of Manufacturing Ststems

该研究项目涉及制造系统的有效生命周期支持问题，包括设计、实施、规划和控制、维护、改进、重建和处置。主要研究成果如下：1）虚拟制造系统技术是全生命周期支持的核心部分，是不同活动之间信息共享的体现。它可以集成系统的三个方面的多样性：时间，空间和应用。2）该研究项目显示了主动知识档案的概念，使存储制造知识与丰富的信息周围的知识。3）提出了全生命周期维护的概念，并给出了全生命周期维护的具体方法。这就要求制造系统设计者在考虑生产率的同时，还要考虑可维护性、安全性、健康性，并指出了新制造系统需要解决的一些问题。提出了虚拟制造系统的构建标准;提出了制造知识的系统化收集方法;提出了制造系统生命周期评价方法

This research project deals with the problem of efficient life-cycle support for manufacturing systems including design, implementation, planning and control, maintenance, improvement, re-construction, and disposal. The primary results of this project are summarized as follows.1) The technique of virtual manufacturing systems is the core part of the life-cycle support and presents the field of information sharing between different activities. It can integrate three aspects of system diversity : time, space, and applications.2) The research project shows the concept of active knowledge archive which enables to store manufacturing knowledge with rich information around knowledge. The implementation was examined by using VirtualWorks.3) The concept of life-cycle maintenance was proposed and the concrete method of it was presented. It requires manufacturing system designers to consider maintainability, safeness and health as well as productivity.The research project also indicates some problems to be solved for new manufacturing systems. They are1) Definition of standards for constructing virtual manufacturing system2) Systematic collection of manufacturing knowledge with situation descriptions3) Development of LCA methods for manufacturing systems
