For environmentally conscious manufacturing, end-of-life (EOL) assembly products should be disassembled for reuse and recycling. In this remanufacturing, the disassembly systems essentially consist of disassembly and sorting processes, and the product sorting process involves reverse blocking which impacts and reduces the total productivity of the remanufacturing. This paper models and analyzes the sorting process in the disassembly system with reverse blocking in consideration of traffic and buffer capacities by a queueing theory. First, the traffic and buffer capacities in the sorting stations are modeled on a sorting queueing system,and the evaluation functions of this system are set as the reverse blocking probability and the system throughput. Next, a transition diagram of the system is drawn, and the stationary state equations of the system are generally formulated with the traffic and buffer capacities. Finally, the system performance is discussed in terms of the buffer capacities, the system balancing among arrival, sorting and disassembly abilities, and a buffer allocation plan.
