Research on Origin-based Cold Storage Location and Routing Optimization of Fresh Agricultural Products Based on Hybrid Whale Algorithm

Abstract

Aiming at the problem that the number of origin-based cold storages is insufficient and the resources are unbalanced in China, this paper studies the location and routing problem (LRP) of origin-based cold storage for fresh agricultural products. This paper considers the loss of fresh agricultural products, and constructs a cold storage LRP model. To solve this problem, a hybrid whale algorithm is designed, and the effectiveness of the algorithm is verified by standard instances. Finally, taking Chenggu County as a practical case, the influence of cold storage capacity and farmers demand for refrigeration on LRP are analysed. Experimental results show that the algorithm proposed in this paper has a good effect in solving the medium-scale LRP. The cold storage capacity has an important impact on the LRP results. With the increase of farmers’ demand for refrigeration, the number of cold storages and vehicles increases, the total system costs increase gradually.
