| Summary: | 碩士 === 元智大學 === 工業工程研究所 === 82 === In this thesis, the role of a process planning expert system
,based on an object-oriented feature-based part model, in a
concurrent engineering environment, is studied first. A
hierarchical process planning framework, which emphasizes and
generates information of intermediate workpiece shapes and
specifications, is proposed. Based on this hierarchical
structure, a feature-based process planning system is
developed, associated with a generic expert system. The
designated generic expert system significantly reduces
constraints of usiing commercial expert system package for
process planning. The databases and rule bases of the developed
generic expert system are thoughtfully designated to provide a
friendly and flexible construction environment for the user.
Following simple guiides to build knowledge bases of different
engineering. the system can support other concurrent
engineering system to carry out tasks of heuristic reasoning
for related engineering processes.
