| Abstract | There is a growing interest for the design and operation of closed loop supply chain systems due to the cost and the legislation issues. In this paper, we address the disassembly, refurbishing and production operations in a closed loop supply chain setting for modular products such as computers and mobile phones considering the uncertainties in this system, which are the return amounts of the used products and demand for final products. We develop a large scale mixed integer programming model in order to capture all characteristics of this system and use two-stage stochastic optimization and robust optimization approaches to analyze the system behavior. In the first stage, we focus on the strategic decisions about the capacities at disassembly and refurbishing sites considering different scenarios regarding the uncertainties in the system. In the second stage, we analyze the operational decisions such as production, inventory and disposal rates. We observe through our extensive numerical analysis that the randomness of demand and return values effect the performance of the system substantially and the uncertainty of the return amounts of used products is much more important than the uncertainty of demand in this system. |
