Recently, the product design technology with CAD and CAE is widely applied to many products. However, useful knowledge contained in the digital data was not positively reused. In order to shorten the development time of the similar products in the large assembly systems, it is especially important to establish the standardizing design process and reuse the design knowledge. Therefore, we have developed two effective approaches to improve the thermal design for large assembly products with reusable analysis models. First approach is to define the hierarchical model tree and modular division. Second is to standardize the data configuration and the modeling process in the design team. As a result of applying this method to a commercial satellite, we verified that profit and loss point was appeared at the time of three or four products developed. And the development time per a satellite was shortened by 30% at the case of 40% reuse rate using proposed Modeling For Reuse (MFR).
