摘　　要：多物理耦合自动建模软件Super MC/MCAM能够有效提高复杂核装置设计分析的效率与质量。核反应堆中具有大量几何相同部件的模型,为了进一步提高MCAM处理复杂问题的效率,本文研究并实现了一种基于相似性评价的模型重用方法。该方法从专家库和建模历史中检索和判断具有相似性的几何模型,并重用其建模结果。使用包括聚变反应堆在内的多种模型的测试结果表明,该方法能够有效提高建模效率。CAD/Image-based Modeling Program for Nuclear and Radiation System （MCAM） has been widely used for nuclear analysis of complex devices. It helps to produce suitable models with radiation transport simulation codes in an efficient, less error-prone way. In order to further improve the efficiency for complex problems, this study introduced and implemented a similarity estimation based model reuse technique. The method retrieves the solids in an expert library and the history of the algorithm execution and then estimates the similarity between the target solid and the retrieved solid. The history result could be reused with a transformation between the two solids. The test results with some fusion reactor models showed that the method could improve the efficiency of the modeling process.
