项目摘要

The Objective of this research is to realize a virtual manufacturing environment which enables to predict product functionality and manufacturability by organizing engineering knowledge systematically in computer compatible form, and to rigorously formalize the concept of concurrent engineering which has been subject to human ambiguous technical know-how and difficult to be transferred to others. For this objective the following items have been investigated.(1) Organization of virtual manufacturing and concurrent engineeringBy surveying the practice of industry, architecture of advanced manufacturing systems has been investigated for concurrent engineering based on virtual manufacturing. Prototype systems have been implemented for collaborative work in design and manufacturing preparation activities.(2) Extraction and systematization of kernel engineering knowledgeBasic engineering knowledge based on physical principles has been extracted and organized, such as dimensions, tolerances, assembly, behavior, etc., and has been organized in database.(3) Generic methods for construction of integrated engineering knowledge basePrototype systems have been constructed for flexible description of complicated semantics of engineering knowledge by use of symbolic mathematics, non-standard logic and object oriented concept.(4) Prototyping of integrated engineering knowledge basePractical engineering knowledge has been described, such as optical components of copiers and automotive engine subassembly, and has been evaluated for its usefulness.A method of construction of engineering knowledge base and organization of product and production process knowledge have been investigated. It is a future work to evaluate practical implication of these results for concurrent engineering.

这项研究的目的是实现一个虚拟制造环境，该环境能够通过以计算机兼容的形式系统地组织工程知识来预测产品功能和制造性，并严格地将同时工程的概念正式形式化，该概念受到人类模棱两可的技术知识，难以将其转移给其他人。（1）虚拟制造和同时工程的组织，通过调查行业的实践，已经研究了基于虚拟制造的同时工程，研究了高级制造系统的体系结构。已经实施了原型系统在设计和制造准备活动中的协作工作。（2）提取和组织了基于物理原理的内核工程知识知识知识的提取和系统化，例如，尺寸，公差，容忍度，组装，行为，行为等，并在数据库中构建了整体方法。已经描述了通过使用符号数学，非标准逻辑和面向对象的概念的工程知识的语义。（4）已经描述了综合工程知识基础层面工程知识的原型制作，例如复印机和自动化引擎副构成的光学组成部分，并已评估了其有用的工具知识和生产的知识基础和生产方法。评估这些结果对并发工程的实际含义是一项未来的工作。
