The Study of Traffic Police Required Spare Parts Supply Chain Network Design

Today one of the most important issues that has attracted the attention of most organizations is the supply chain management. Having good supply chain is the first step in designing the appropriate supply chain network. In this research traffic police required spare parts supply chain network design is introduced so that the total cost is minimized. The research case study is traffic lights. By providing a numeric example and solving it by Simulated annealing meta heuristic algorithm, it is displayed that the total cost is minimized. The results of this study and the sensitivity analysis of this research indicated that by changing the optimized response in any case the cost will increase. It is worth mentioning that the whole data in this research is produced randomly and based on rational and logical criteria and trial and error methods.
