A Survey of Design ? Analysis Integration Issues

The report constitutes a survey of work directed towards the emergence of nextgeneration product development tools, specifically in the area of design-analysis integration. The report is organized into two main areas: (1) an examination of issues pertaining to design processes and information generation and capture; and (2) a literature survey of current design-analysis integration efforts. First, engineering design is presented and discussed in terms of the product data that are generated during the design process. Based on analyses of the Pahl and Beitz systematic design process and the National Institute of Standards and Technology (NIST) Core Product Model (CPM), a correspondence between deliverables in the design process and the information that can be captured in the CPM is generated. The primary objectives of this task are to identify the basic information-generating activities in the design processes and to verify the comprehensiveness and completeness of the CPM in its ability to support the storage and retrieval of the information generated. The second area covered is a comprehensive literature survey of current design-analysis integration research thrusts and efforts. It was found convenient to classify current research into three general categories: (1) object-oriented modeling paradigms of mechanical systems; (2) efforts in the area of Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE) integration; and (3) multi-aspect information structures. The literature survey suggests that there is a strong need for a common vocabulary, framework, and roadmap for the improved integration of design and analysis tools to be used in next-generation product development systems. By developing a standard vocabulary and framework, synergies in design-analysis integration and product modeling can be leveraged to decrease the gaps and increase product development efficiency.
