摘要
为提高物流系统的服务水平,对具有经济性和时效性的配送中心选址问题进行了研究.以经济费用最小为目标,将客户对送货时间的要求转化为时效性约束条件,构造配送中心选址模型.讨论了求解该选址问题的优化算法——序列二次规划算法(SQP).通过实际算例对选址模型和求解算法的可行性进行了检验.算例结果表明:模型和算法能很好地解决有时效性约束的配送中心选址问题,对提高物流系统的运作效率有积极的意义.
The distribution center location based on economics and timeliness was studied to improve the service level of logistics system. A model with time constraint was proposed to optimize the location with the target of minimizing total cost. The sequential quadratic programming （SQP）, one of the solution methods to this model, was discussed. One case of distribution center location was solved by using the location model presented and the SQP. The results indicate that the location model and SQP can optimize the distribution center location with time constraint effectively.
