Abstract: Parts design scheme selection for supplier involved new product development was studied. The concept of integrated performance indicator was introduced as a performance measure of design scheme to reveal contribution of parts design scheme to total customers satisfaction with product. Taking the roles of suppliers and fuzzy synthesis evaluation into consideration, integrated performance indicator was determined by aggregating evaluation class of its supplier and the standby design scheme. Based on the principles of Quality Function Deployment, the quality houses of product planning and parts planning were established. A 0-1 integer linear programming model for parts design scheme selection was developed based on the information generated in the product planning and part planning House of Quality and the integrated performance indicator. The model aimed to maximize the weighted sum of integrated performance indicator while taking into consideration of the design resource constraints and financial factors as well as information from competitors. A case study of development of LCD in a company was provided to illustrate the application of the model.
