Study on Location of Fresh Food Distribution Center with Demand Influenced by the Freshness

This paper mainly focuses on the fresh food and assumes that its demand is influenced by the freshness. It's a new assumption that is more practical and closer to customers' purchase psychology. Based on the assumption, the paper establishes a location model of fresh food distribution center. We use a heuristic algorithm—ADD for the model to obtain the initial solution, and then the initial solution is improved by neighborhood search exchange algorithm to get the optimal solution. Finally, the paper verifies the effectiveness of the model through a case. This study contributes to optimize the fresh food cold-chain distribution system so as to improve the logistics efficiency.
