| 摘 要： | 应用Matlab优化函数求解带时效性约束的物流中心选址问题。分析选址问题的时效性约束条件，构造带时效性约束的物流中心选址模型，利用Matlab优化工具箱中的“fmincon”函数，设计选址模型的精确算法，并给出具体算例，验证模型和算法的可行性。研究结果表明，基于Matlab函数的优化算法编程简单，运算速度快，既能够求解带时效性约束的选址模型，又能够求解不带时效性约束的重心选址模型，是一种比传统算法更有效的求解物流中心选址问题的算法。

| Abstract: | This paper studied the algorithm of logistics center location problems with time restrictions by Matlab optimization function. A location model with time restrictions was developed,an exact algorithm based on the 'fmincon' function in Matlab optimization toolbox was put forward to solve the model,and an example was calculated to verify the model and algorithm.The results indicate that this algorithm is simple to be programmed and quick to be calculated,it not only can solve the location problems with time restrictions,but also can solve the traditional location problems without time restrictions.So the new algorithm is more effective than the gravity approach in solving the logistics center location problems.3 tabs,9 refs. |
