To meet the fast-change market, products have to be improved continuously through design change processes. The design change process is the most frequent activity in its life cycle. When a change for a design is initiated, its related components need to be changed and that results in the changes of other related components. This starts a chain reaction. The product data usually include the data that may be generated throughout its life cycle, such as the design chart, manufacturing/production information, user¡¦s information, etc. The data formats varied at each stage of the product and its amount is too large for a simple database to handle. We need a system to manage these data which is called a Product Data Management¡]PDM¡^system. When a chain reaction occurs, it may cause a series changes among enterprises. We need a method to constrain the affected domain, and provide necessary data to proceed the change process.
In this research, we are dealing with the design change issues by sharing product information stored in PDM systems. The purpose of this research is to construct a product data-sharing framework so that design change process can be carried out through the computer network. A product data search engine¡]PDES¡^will be used as the core of this framework. The PDES consists of several algorithms and assembly rules. The major function of the PDES is to find out proper parts, and then get their data through the network to meet the design change requirements. The design change processes are usually result in decision-making problems caused by distributed data and inconsistency of data formats. These problems can be solved by the proposed framework. The configurations of a personal computer and a bicycle are used as examples to demonstrate the analysis and modeling procedures.
