Research on Layout Problem of Multi-layer Logistics Facility Based on Simulated Annealing Algorithm

This paper is divided into two stages to study the layout problem of multi-layer logistics facility of irregular shape, across floor with no divided section. The first and the second stage model are respectively established for the goal that the cost of materials vertical movement and horizontal movement are minimum. On the basis of the first stage arrangement scheme obtained by means of Constitutional formula solution, optimal arrangement scheme of the second stage is obtained based on the ideas that combing simulated annealing algorithm and space-filling curves. Through the example analysis, the solution method of this article can offer a certain reference for researching layout problem of multi-layer logistics facility.
