The modeling method to support product development processes (PDP) must have certain characteristics including the ability to represent multiple viewpoints of the product development and integrate with currently available analysis and design methods based on CE concept. This paper describes the reference model to support multiple viewpoints (PPO: Products, Processes, and Organizations/Resources viewpoints) of the product development processes, from which each model (Products model, Processes model, and Organizations/Resources model) can be extracted, as well as produces PPO data schema. This reference model has associative relationships among the products, processes, and organizations/resources. To allow the extensibility to support design evolution, we propose structured dat representation methods using semantic network, which can be constructed through first-order logic. The product development processes is so represented by specifying entities and semantic relationships among them hat he appropriate information can be accessed and all of the relevant attributes about the entities can be retrieved simultaneously.

Currently the systematic approaches to implementing CALS and reducing time-to-market are widely used, which is based on the concept of PDM. The concept of PDM is to maximize the time-to-market benefits of concurrent engineering while maintaining control of product data and distributing, it automatically to the people who need it - when they need it. In this paper, we developed PRO browser with these PDM functions which have the functions of managing the information of product, process and organization consistently and inter-referencing efficiently the data required in enaluation. In the PRO browser, throughout the design process improvement, the generic environments are embodied which make it possible to reduce product development sycle time and improve the quality of design.
