The design of automotive disassembly and recycling program is very difficult, and its implementation cycle is long and the efficiency is low. For these problems, a knowledge reuse method of automotive typical parts disassembly and recycling is put forward by applying rough set theory, and the key technology of knowledge reuse is researched. The knowledge of automotive disassembly and recycling is expounded, and the characteristics of disassembly process are determined. The discrete algorithm and reduction processing of the characteristics of disassembly process is conducted based on rough set theory, and the feature attribute weights of disassembly process are calculated. The retrieval mechanism and similarity calculation method between similar cases are given. By taking the interior and exterior decoration of a car as an example, the practicability of this method is verified.
