Vendor managed resupply is an emerging trend in logistics and refers to a situation in which a supplier manages the inventory replenishment of its customers. Vendors save on distribution cost by being able to better coordinate deliveries to different customers, and customers do not have to dedicate resources to inventory management anymore. We present and discuss the inventory routing problem. ...

Supplying of blood and blood products is one of the most challenging issues in the healthcare system since blood is as extremely perishable and vital good and donation of blood is a voluntary work. In this paper, we propose a two-stage stochastic selective-covering-inventory-routing (SCIR) model to supply whole blood under uncertainty. Here, set of discrete scenarios are used to display uncerta...
This paper considers a single-sourcing network design problem for a three-level supply chain. For the first time, a novel mathematical model is presented considering risk-pooling, the inventory existence at distribution centers (DCs) under demand uncertainty, the existence of several alternatives to transport the product between facilities, and routing of vehicles from distribution centers to c...
Inventory management and transportation issues are very important problems in distribution companies. Simultaneous l optimization of these problems realizes significant savings for all partners of the supply chain. One of the problems that should be addressed in the scope of simultaneous sl optimization is the inventory routing problem (IRP). IRP deals with how to manage the supply goods from o...
Abstract In the Inventory Routing Problem, customer demand is satisfied from inventory which replenished with capacitated vehicles. The objective to minimize total routing and holding cost over a time horizon. If customers are located relatively close each other, one has opportunity satisfy of by stored at another nearby customer. optimization replenishments, this option can be included lower c...
The purpose of this paper is to determine the route of the vehicle routing problem with backhauls (VRPB), delivering new items and picking up the reused items or wastes, and resolve the inventory control decision problem simultaneously since the regular VRPB does not. Both the vehicle routing decision for delivery and pickup, and the inventory control decision affect each other and must be cons...
