Abstract: The recovery of Waste Electrical and Electronic Equipment（WEEE） has become a major issue for solid waste being dangerous to the environment and human health. Exploring new ways to dispose of WEEE has become mandatory in avoiding such hazards and enhancing the effectiveness of resources. A key role to achieve this goal is the reverse logistics network design for WEEE. Taking into account the uncertainty of WEEE reverse logistics network operation, a robust optimization model for WEEE reverse logistics network operation is established based on the risk preference coefficient?and penalty coefficient deviated from the constraints. The model can allow decision-makers to adjust the robust level of the operation system and risk preferences. The simulation of the model shows that the robust optimization model is better than the classic model and has a lower operation risk, which can give consideration to the cycles of different circumstances and is effective in inhibiting the uncertainty of WEEE reverse logistics system operation.
