System dynamics simulation of used productions recovery logistics network for manufacturing companies

To study the dynamic development mechanism of used productions recovery logistics network, categories and characteristics of used productions are analyzed aiming at manufacturing companies, recovery network with multi-layer is designed, and a system dynamics model with “social-economic-logistics” triple properties is established based on system dynamics theory. A simulation which takes used mobile phones recovery as a case study is set. The results show that the model established in this paper is valid for simulating the dynamic development processes of used productions recovery logistics and can be served as a computer aided decision tool for managers to control the cooperation organization.
