Simulated Annealing algorithm and its application in logistics park location

Yan-yan Liu


The logistics costs include the cost of transportation, warehousing, information management, land costs and environmental protection. It is an important influence factor of the logistics facilities location. The location of logistics park and vehicle routing arrangement directly determine the logistics cost. Compared with the conventional location allocation model, the location routing model is more closer to reality. Based on the traditional the facility location model and the transport vehicle routing model, this paper establishes the location routing model making the generalized cost minimum as the goal . Moreover, this paper uses simulated annealing algorithm to solve the model and gives its steps. By using the simulated annealing algorithm ,we get the facilities location and the vehicle routing, optimize the location of the logistics facilities and the distribution paths, and verify the practicality of the model.
