Product demand modeling based on use cases in service marketing

In this paper a new demand modeling method for new products - product demand modeling method based on use cases is put forward. Compared with the existing demand modeling method, it has the following characteristics: first, from the perspective of new product development, meanwhile supporting variant design of existing products. Second, the detailed product demand information is acquired using the use cases in software engineering. Third, with motor products, the applied research has been made further. In this paper quality function deployment and use cases are combined to analyze the acquiring of demand information, then to define product demand fuzzily, finally to realize the mapping from the customer demands to product engineering properties. With the analysis a theoretical guidance can be provided for the enterprises to improve product design quality and to shorten new product time-to-market.
