在本文中，我们解决了现实生活中的分销问题所面临的摩洛哥瓶装水公司处理的库存和分销决策相结合。为了管理其分销流程，该公司使用供应商管理库存系统，这意味着供应商控制客户的库存。这个问题被称为库存路由问题（IRP），其中运输和库存成本同时最小化。我们的现实生活中的问题包括几种类型的瓶装水，必须从供应商运送到一组区域仓库和批发商。库存成本由工厂和客户支付，运输由一个同质车队执行。我们提出了一个特设的修改IRP模型和分支和切割算法。在15个基于现实生活的实例上进行了计算测试。结果表明，可以获得近10%的显著节省。[接收日期：2016年3月20日;修订日期：2016年8月21日;接受日期：2016年9月10日]
In this paper we solve a real-life distribution problem faced by a Moroccan bottled water company dealing with a combination of inventory and distribution decisions. To manage its distribution process, the company uses a vendor-managed inventory system, which means that the supplier controls the inventory at the customers. This problem is known as the inventory-routing problem (IRP) in which both transportation and inventory costs are simultaneously minimised. Our real-life problem contains several types of bottled water that must be shipped from a supplier to a set of regional depots and wholesalers. Inventory costs are paid at both the plant and at the customers, and shipments are performed by a fleet of homogeneous vehicles. We propose an ad-hoc modification of IRP models and branch-and-cut algorithms. Computational tests were carried out on fifteen real-life-based instances. The results show that significant savings of almost 10% can be obtained. [Received 20 March 2016; Revised 21 August 2016; Accepted 10 September 2016]
