This paper introduces the Inventory-Routing Problem with Transshipment (IRPT). This problem arises when vehicle routing and inventory decisions must be made simultaneously, which is typically the case in vendor-managed inventory systems. Heuristics and exact algorithms have already been proposed for the Inventory-Routing Problem (IRP), but these algorithms ignore the possibility of performing t...

Heretofore several position-based routing protocols have been developed for mobile ad hoc networks. Many of these protocols assume that a location service is available which provides location information on the nodes in the network.Our solutions decrease location update without loss of query success rate or throughput and even increase those.Simulation results show that our methods are effectiv...

Inventory-routing problems (IRPs) arise in vendor-managed inventory systems. They require jointly solving a vehicle routing problem and an inventory management problem. Whereas the solutions they yield tend to benefit the vendor and customers, solving IRPs solely based on cost considerations may lead to inconveniences to both parties. These are related to the fleet size and vehicle load, to the...

The mobile nodes in MANETs dynamically change their topology and hence require an efficient mechanism to communicate with each other. There are number of routing protocols anticipated for MANET environment categorized as Location based routing protocols and Non-Location based routing protocols. In MANETs, Location based routing protocols are preferred as they are more efficient in routing compa...

Objective: Designing a CPFR (collaborative planning forecasting and replenishment) model for the delivery of diabetes arterial hypertension medicines from health insurance company (EPS) to healthcare provider (IPS) comparing performance this collaborative chain that traditional one through their corresponding supply costs. Methodology: A series collaboration agreements involved in joint were es...

T work is motivated by the need to solve the inventory routing problem when implementing a business practice called vendor managed inventory replenishment. With vendor managed inventory replenishment, vendors monitor their customers’ inventories, and decide when and how much inventory should be replenished at each customer. The inventory routing problem attempts to coordinate inventory replenis...

This paper introduces an integrated approach for solving the Period Vehicle Routing Problem with Simultaneous Delivery and Pickup (PVRPSDP). The problem considers a dis tribution system consisting of a warehouse and many dispersed location retailers, where each of which having two type of demands to be delivered and collected, respectively. A fleet of capacitated vehicle is employed for deliver...
