Abstract
The collaborative design process can be viewed essentially as the evolution of product data, which is the results of a series of decisions. Contemporary product data representations in describing design deliberations are either informal with plain text or insufficient using some simple data structures. Explicit modeling of the evolution, alternatives and constraints of the product data in a large design space is crucial for capturing the process information at any a state of its recorded history. This paper develops a product data model on the basis of the integrated generic resources from STEP1, which is used to formally describe the objective of a task, assignments and alternatives etc. of a decision, and in particulars, the constraints among decisions. A product model-oriented representation of the collaborative design process is proposed to develop a database which addresses the archiving of design history. The proposed representation focuses on the formal specifications of the process ingredients and the dependencies among these ingredients, such as product-data-model, assignment, activity, task, negotiation, and agent. Accordingly, a data model is developed in EXPRESS2. An object-oriented database is under development to implement the data model.
