This research proposes computational models for concurrent design process of large complicated systems as the formal fundamentals for the development of agent-based distributed design support systems. In this first report, we assume that an artifact is modeled with a set of lumped mass systems and that the number of variables is fairly huge to facilitate the discussion. Under these assumptions, the design phases, the types of design knowledge, and their characteristics such as granularity levels, operational cost, fedility, dominatedness, etc. are formally discussed. Furthermore, the design model is primarily decomposed into the global model and domain models, and the horizontal and vertical decomposition of a design process are formulated. Following such decomposition structure, the conception of goal cascading is proposed as a model of coordination structure among the divided design tasks. The goal means the play on an intermediate variable shared among distributed tasks. The discussion deducts three types of coordination: inter, global and inner ones. These understandings are expanded to operational models and a computer-aided design support system in the succeeding papers respectively.
