项目摘要

In most advanced industrial society, it is strongly desired to achieve flexible variable-type variable-volume production, and it is extremely difficult to realize optimized manufacturing due to the lack of repetition of similar production. Therefore it is considered to be appropriate to reduce the prototyping and experiments in production processes by use of physical objects, but to increase the efficiency and quality of production by use of computer aided methods. In this research, a concept of virtual manufacturing and comprehensive simulation of product functionality and manufacturability based on product/process models and associated factory models have been investigated. The major results are summarized as follows. (1) The framework for product/process modeling has extended to enhance the ability of technological information representation, and to increase process simulation capability for product functionality and manufacturing processes. In particular, dynamic behavior of machine assembly motion is precisely related with the product specification in order to realize systematic improvements of product design. (2) A concept of factory modeling is discussed, and its basic components are identified. (3) Virtual manufacturing environment which consists of software tools is considered, and some of the prototypes of the tools have been prepared for use in subsequent research activities. In this research, highperformance graphics workstations were acquired by the assigned budget, and the rest of the budget was spent for software works and related cost.

在大多数先进的工业社会中，强烈希望实现柔性可变类型的可变容量生产，并且由于缺乏类似生产的重复，因此实现优化制造是极其困难的。因此，它被认为是适当的，以减少原型和实验在生产过程中使用的物理对象，但要提高生产的效率和质量，通过使用计算机辅助方法。在这项研究中，虚拟制造的概念和产品功能和可制造性的综合仿真的基础上的产品/过程模型和相关的工厂模型进行了研究。主要结果总结如下。(1)产品/过程建模的框架已经扩展到增强技术信息的表达能力，并增加产品功能和制造过程的过程仿真能力。特别是，机器装配运动的动态行为与产品规格精确相关，以实现产品设计的系统改进。(2)工厂建模的概念进行了讨论，并确定其基本组成部分。(3)虚拟制造环境，其中包括软件工具被认为是，和一些原型的工具已准备用于在随后的研究活动。在本研究中，高性能的图形工作站是由指定的预算购买，其余的预算用于软件工程和相关费用。
