The materials and combination of Waste Electrical and Electronic Equipments (WEEE) are complex and special, so the recycling technological process of WEEE is complicated and its recycling production line is difficult to be constructed. To improve the rate of parts reuse, the purity and quality of recycling materials with lower cost, it is necessary to manually disassemble WEEE products as much as possible. The recycling production line is simulated through the eM-Plant software to find out its bottleneck procedures. The bottleneck procedures are eliminated through the method of parallel process. The production efficiency, cost, logistics, staff and flexibility of the production line are analyzed through simulation.
