The case retrieval is the core of the case-based reasoning system. The paper applies performance prediction into the case retrieval based on case reasoning system, designs a retrieval strategy based on heterogeneous case base. The paper analyzes the organization fashion of the heterogeneous case, and mainly discusses the dynamic allocation strategy of characteristic items' weight and construction method of the case retrieval log. The results of the experiment prove that the method can support users to build the target case and then efficiently enhance the success rate of case retrieval as well as the utilization rate of case base.
