Optimization of Electronic Waste Recycling Network Designing

Reverse logistics is an important part of a low-carbon economy. Electronic waste recycling logistics network design plays an important role in reverse logistics management. In this paper, a multi-objective planning is used to establish a network model of electronic waste recycling. The objective function is to minimize operating costs and maximize customer service levels. The decision variables include the setting of nodes in the recycling network and the amount of transportation between the nodes of the network. Constraints include meeting customer needs and balancing the inflow and outflow of nodes. The multi-objective programming is transformed into a single-objective programming by e-constraint. The numerical example shows that the two objects can be consistent within a certain range, so that the electronic waste logistics enterprise can achieve the goals of simultaneously reducing costs and improving customer service levels.
