Abstract: Aiming at the problem that the service coverage of business enterprises' cloud warehousing had overlapped caused by its dense distribution,two key factors included the logistics cost caused by shortage and transfer between different warehouses and the scope of business enterprise service were proposed.With the goal of minimizing the total cost of logistics,a cloud warehousing distribution and optimization model was established.Then,two optimal tabu search algorithms and genetic algorithm were designed to solve the problem.Two algorithms were compared with the existing algorithm in terms of convergence,optimal solution and distribution variance of cloud warehousing.The result showed that the total cost of logistics of cloud warehousing using tabu search algorithm was lower after considering the above key factors.Based on the tabu search algorithm,the distribution variance was larger,the distribution of cloud warehousing was more scattered,and the service radiation range of business enterprise was wider,which verified the feasibility and effectiveness of the tabu search algorithm.
