New cell phone styles and technologies developments are changing quickly. To improve the ability of competition for a company, a new designed cell phone has to be available in the market in the short time. Therefore, production processes including manufacturing machine choice for a new cell phone product have to be determined quickly. Facing the lack of information, it is difficult to choose manufacturing machines for a production process for a new product. Thus, this study proposed a Collaborative Production Machine Choice System (CPMCS) based on a hierarchical case based reasoning approach to solve the problem of machine choice for new cell phone production. A real interaction system is built up also to help users for machine choice in this study. Using non-fixed number of new product features, this system can advise suitable machines for users by case based reasoning approach and help users to find out the right machines for production in the short time.
