The method and model of product planning were studied based

on the theory of design domains herein.The method was started from the

customers’ requirements for the product quality and developed upon a benchmarking product which was selected according to the product positioning. It was explored based on quantifying the cascading mappings among four design domains’ representative parameters, i.e. customers’ requirements, functional requirements, design parameters and process variables. By integrating the analysis results,a goal programming model was set up to achieve the design solution which involves customer’s satisfaction,production cost and investment. By way of illustration, a medium sedan was designed and its results demonstrate the effectiveness and practical value of the method.
