Design knowledge is very useful in space product design tasks. In this paper, the knowledge representation and reuse technology of space product design knowledge is studied, and a new case-based knowledge reuse method is presented. In the method, the case retrieval strategy that adopts the similarity-based case retrieval algorithm based on a new model is proposed. This new multilevel case model in which mapping relationship and multiple tree are the characters is constructed by analyzing the process of space product design based on the process of rocket design. Finally, the proposed method and algorithm are verified by applying to the rocket design as an example. It is shown that the new method improves the efficiency of utilization of the design knowledge in the rocket design.
