Examines recent research results on integrated intelligent systems for engineering design based on distributed artificial intelligence (DAI), computer-integrated manufacturing systems (CIMS), and intelligent computer-aided design systems (ICAD). Presents both theory fundamentals and implementation technology, as well as industrial applications. Introduces a new problem-solving strategy for engineering design and its implementation based on integrated distributed artificial intelligence technology in detail. Explores six application case studies, including missile system design, mechanical transmission design, process control system design, and chemical process design.
