Research on Vehicle Routing Optimization for Bulk Waste Shared Collection Model

At present, bulky waste is mainly collected and transported by self-owned vehicles. However, the use of self-owned vehicles for collection has problems, such as high purchase costs and insufficient stability in vehicle configuration, making it difficult to balance the utilization of truck resources and the efficiency of bulky waste collection and transportation. Therefore, this paper proposes a bulky waste collection and transportation model using shared vehicles. Under this model, a scheduling model for shared bulky waste collection and transportation vehicles is designed. The core of the model is to integrate time window constraints and three-dimensional loading constraints. By integrating existing truck resources for scheduling and optimizing the truck scheduling decisions through optimization algorithms, the feasibility and effectiveness of the model are verified through experiments.
