In the early stages of the design process, the conceptual design is the stage that can determine the product cost up to 80% on average. In this stage, there are more than one product concept program to choose from. However, to make a concept prototype, and to survey a sufficient number of consumers need, a lot of time and cost need to be spent. In order to solve the above problems, this paper introduces a real-time innovative design of the network-based customer evaluation and selection methods. This method makes full use of the internet and information technology which is able to quickly transport consumer demand to the conceptual scheme at a lower cost and by calculating the extent of consumer preferences on a variety of conceptual design schemes in a short period time allow consume make their decision on a real-time basis during the design phase.
