Computer Aided Engineering
An embryo CAE system is sketched which reflects both the computer-based tools and the humans that are to use these tools. Key to this description is the inclusion of not just technical aspects but social and management aspects as well. A methodology, based on the IPAD work, is suggested which can help one to identify critical CAE system aspects, such as the activities, the data requirements, and their interactions, both for technical and management processes.
An ideal CAE system is described which is heterogeneous in both hardware and software. The IPAD prototype software work for data management, executive, and network communications are described.
Various marketing approaches, as well as some of the economic factors which appear to influence the potential emergence of the needed CAE system, are evaluated. It is concluded that market forces, not technology, are constraining the emergence of a fully integrated CAE system, effective for engineering data management and task and data communication in a heterogeneous computer environment.
