Study on the location of regional emergency logistics centre based on improved backtracking algorithm

Abstract

Emergency logistics is an essential branch of modern logistics services, and the efficiency and safety of its transport have an important impact on maintaining social order after an emergency. When considering the location of emergency logistics distribution center, the lowest transportation cost should not be the main goal, but the shortest distribution distance should be designed and planned to ensure the timeliness and reliability of emergency supplies. This paper proposes a density coefficient optimization algorithm based on the backtracking algorithm. The results show that the algorithm reduces the complex iterative process in the backtracking step and can select the most suitable distribution centre location in a specific region, which has some practical significance for solving the location selection problem.
