Abstract: To improve the efficiency and effectiveness of recycling scrap tires, the optimization of standardized recycling systems for scrap tires was studied. A multi-period optimization model for Location-Routing-Inventory Problem (LRIP) based on Collector Managed Inventory (CMI) was developed. Accordingly, the joint optimal decision of locating recycle centers, scheduling routes of collection vehicles, and controlling the two-echelon inventory at recycle centers and collection sites can be made. A two-phase heuristic algorithm was proposed. The initial solution was found by using location-allocation first, route and inventory second approach based on minimal system cost in phase 1. An improvement heuristic search for a better solution based on the initial solution in phase 1 was developed in phase 2. A numerical example results showed that the proposed model and algorithm was valid and CMI-based approach can significantly improve the operating performance of recycling systems for scrap tires.
