Study on the Location of Cold Chain Distribution Center Considering Scale Effect

Abstract

People are paying more attention to the freshness of cold chain products when making choices. Establishing cold chain distribution centers can improve the timeliness and service quality of cold chain logistics. Cold chain distribution centers require significant investment, necessitating a more scientific approach to site selection. Furthermore, compared to regular distribution centers, cold chain distribution centers exhibit clear economies of scale, thus necessitating careful consideration of these economies of scale during site selection and construction. The paper analyzes the scale effect of the cold chain distribution center, and constructs a cold chain distribution center location model considering the scale effect. The objective function of the model includes the related costs of the cold chain distribution center location, such as fixed cost, operating cost, transportation cost, loss cost and carbon emission cost, etc., with the minimum total cost as the function objective. Finally, this paper designs a calculation example design. The model calculation example is solved by Lingo software, and the optimal location plan of the cold chain distribution center is obtained. The calculation example results verify the effectiveness of the model.
