Design for multi-period multi-objective product recovery networks based on third party logistics

In view of that multi-period product recovery networks can interpret the complexity of the real-life recovery networks more accurately than single-period ones, and multi-objective ones can give consideration to the benefits of each supply chain member more comprehensively than single-objective ones, a multi-period multi-objective product recovery networks model based on the third party logistics is built. In the model, customers' preference for the nearest collection center is taken into account, and the recovery centers' stock is used to link the waste flows of each period. An example is solved by using LINGO. Then, the goal programming method is applied to discuss the relationship between two objectives, and to analyze the influence on one side when changes occur on the other.
