Abstract The demand for the better quality products with shorter lead-time and lower life-cycle cost forces the manufacturing enterprises all around the world to optimize their production strategies from both enterprise engineering and enterprise operation respectively. This paper addresses the architectural issue of applying the Concurrent Engineering (CE) approach in the composite manufacturing area. It first discussed briefly the characteristics of composite manufacturing process to examine the feasibility and possibility of applying the CE approach to improve its process productivity and product quality. Then the functional requirements for a concurrent engineering system for composites (CESC) were defined from both operational and architectural points of view. Finally, the integrated infrastructure based system architectures for the CESC were presented in accordance with the physical system requirements, and so were the associated and currently conducted R&D focuses for the system.

Abstract Concurrent engineering is focused on improving the Product Realization Process by more effectively integrating manufacturing issues into engineering design. Expansion of the Concurrent Engineering paradigm to include a broader range of concerns is advocated, and this paper examines the integration of legal issues into the Product Realization Process. It describes a prototype legal expert system that focuses on product design based on defective design product liability law. The legal reasoning process is modeled using a fuzzy logic architecture. The goal for this prototype system is the development of a workstation based advisor to engineers that automates assessment of potential legal liability for defective design. As a Concurrent Engineering tool, this fuzzy system allows engineers to make modifications during preliminary design, thereby avoiding the more painful process of modifying designs after litigation. Results with this system are discussed, and it is concluded that the fuzzy logic architecture appears to offer a suitable approach.

Feature Based Design

The centralized planning and control that has defined the traditional information processing structure of manufacturing systems is no longer suited to the current rapidly changing manufacturing environment. For efficient use of manufacturing resources and increased flexibility, it is necessary to migrate to a distributed information processing system in which individual entities can work cooperatively towards overall system goals. The next generation of manufacturing systems requires such an information technology framework to integrate the system components and activities into a larger collaborative enterprise. This paper describes a multi-agent approach to concurrent design, manufacturability analysis, process planning, routing and scheduling. A heterogeneous multi-agent concurrent engineering system consisting of multiple feature-based design sub-systems, multiple simulated shop-floor resource groups, a supervisory control interface and the coordination mechanisms for multi-agent cooperation, has been developed. The architecture of this distributed system and the associated implementation issues are discussed.
