This document presents a methodology for the optimal selection of the vehicle fleet necessary to distribute medical products from the company’s storage center to many intermediate transfer nodes, and from these to a group of public hospitals. The problem addressed is a real case presented by a company that provides logistics services in the Mexican Republic. An algorithm that incorporates three modified mathematical models was designed for its solution. A version of the Dijkstra algorithm was modified for the solution to develop the clustering of nodes (clinics) within the system. A modified version of the model of the traveling salesman generated the routes of the transports and the sequence of distribution of the products. Finally, a model of mixed integer linear programming provided the quantities and characteristics of the transports to buy.

在诊所和医院分配药物的最佳物流策略

本文档介绍了一种最佳选择所需车队的方法，该车队将医疗产品从公司的存储中心分发到许多中间传输节点，再从这些中间节点分发到一组公立医院。解决的问题是一家在墨西哥共和国提供物流服务的公司提出的一个真实案例。针对其解决方案设计了一种算法，该算法包含三个修改后的数学模型。修改了Dijkstra算法的版本，以解决该问题，以开发系统内节点（诊所）的集群。旅行推销员模型的修改版本生成了运输路线和产品分配顺序。最后，一个混合整数线性规划模型提供了要购买的运输工具的数量和特征。
