Product Requirement Modeling and Optimization Method based on Product Configuration Design

Product requirement modeling is a process that the product requirement information is collected, analyzed, structured and converted to the design specification, it is the determinant of the ability to quickly respond to the diverse requirements of customers. This paper presents a product requirement modeling method based on configuration design, which uses "tabular layouts of article characteristics" (SML) technology to conduct the formal expression of product requirement information element. The function structure model and its optimization algorithm are proposed. Enterprises can use the model to interact with customers about requirements and obtain the model which can be manufactured. The customer individual requirements can be satisfied according to the mapping rules of models. Finally, an example of enterprise application is given to illustrate practical application of the research. (C) 2015 The Authors. Published by Elsevier B.V.
