I. Introduction
At Present, China's economic development enters a stage of transformation and upgrading for industry 4.0 technologies and industrial informatics. It is an urgent need to improve quality and efficiency for recycling, remanufacturing, manufacturing assembling and disassembling activities. Waste electromechanical products can be regarded as a kind of renewable resources, which often contain a high proportion of precious metals and reusable parts. A good recycling not only alleviates the current situation of resource tension, but also reduces manufacturing costs. Disassembly is an important means to recover renewable resources from used electromechanical products while realizing the remanufacturing of electromechanical products.
