摘　　要：物流选址和物流车辆路径问题是物流研究领域中的基本NP-hard问题,本文从研究问题混合数学模型和模型算法出发,基于当今最流行的优化计算软件LINGO快速优化混合整数规划问题最优解,使问题优化过程更便捷和更高效。本文通过将混合数学模型转化为LINGO语句,编写了优化物流选址和物流配送路径这两类问题的LINGO程序代码,并通过相关算例验证了此LINGO程序代码可以快速有效求得这两类问题的最优解,算例表明模型是正确的,根据模型设计的程序是可行的;另外本文优化程序可为国内物流选址和路径规划研究和应用提供了参考意义和借鉴价值。Logistics location and logistics vehicle routing problem are the basic NP-hard problems in the field of logistics research.Based on the most popular optimization software LINGO,we can optimize the mixed integer programming problem quickly,which makes the optimization process more convenient and efficient.By turning the mixed mathematical model into a LINGO statement,this paper has compiled the Lingo Program Code for optimizing logistics location and logistics distribution path.It is proved that this LINGO program code can quickly and effectively obtain the optimal solution of these two kinds of problems.The example shows that the model is correct and the program designed according to the model is feasible.In addition,the optimization program can be used for reference in the research and application of logistics location and route planning in China.
