基于改进原子算法的物流配送中心选址策略

Location Strategy of Logistics Distribution Center Based on Improved Atomic Algorithm

针对电商物流配送中心选址难以优化,导致配送成本过高、配送效率低的问题,提出一种改进原子算法的电商物流配送中心选址模型。针对基本原子算法易早熟收敛而陷入局部最优、局部收敛精度不高的问题,通过提出一种非线性控制因子对算法进行改进,提高算法的收敛精度,同时引入正弦混沌搜索策略来帮助算法跳出局部最优。最后将改进后的原子算法对电商物流配送中心选址模型进行优化。实验结果表明:优化后的选址模型有效地节约了配送成本,提高了配送效率,增加了电商企业的效益。

Concerning the location of e-commerce logistics distribution center is difficult to optimize,resulting in high distribution cost and low distribution efficiency,this paper proposed an improved atomic algorithm for e-commerce logistics distribution center location model.In order to solve the problem of premature convergence,falling into local optimum and low accuracy of local convergence of basic atomic algorithm,a nonlinear control factor was proposed to improve the convergence accuracy of the algorithm.At the same time,sine chaos search strategy was introduced to help the algorithm jump out of local optimum.Finally,the efficiency of the distribution center was improved,and the results showed that the efficiency of the distribution center was improved.
