In warehouses, storage replenishment operations involve the transportation of items to capacitated item slots in forward area from reserve storage. These are later picked these as demand arises. While order picking constitutes majority warehouse operating costs, efficient management is important ensure availability for and decrease costs due replenishment, which might be particularly higher war...

This work is motivated by the need to solve the inventory routing problem when implementing a business practice called vendor managed inventory replenishment (VMI). With VMI, 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 replenishment and transportation i...

Location-Routing Problem (LRP) emerges as one of the hybrid optimization problems in distribution networks in which, total cost of the system would be reduced significantly by simultaneous optimization of locating a set of facilities among candidate locations and routing vehicles. In this paper, a mixed integer linear programming model is presented for a two-echelon location-routing problem wit...

Abstract A network of queueing-inventory systems is considered where the inventories are replenished by a common central server. Travel times for transport items send out from center and an adaptive dispatching regime to direct transportation towards locations with incorporated in model. The stationary distribution system product form explicitly given. An optimization procedure developed find g...

Generally, the inventory routing problem occurs in a supply chain where customers consider the supplier responsible for inventory replenishment. In this situation, the supplier finds the answer to questions regarding the time and quantity of delivery to the customer as well as the sequence of customers in the routes. Considering the effect of production decisions on answering these questions, t...

In this paper we present a model and solution procedures of the Inventory Routing Problem (IRP) encountered in vending machine supply chains working under vendor-managed inventory (VMI) scheme. The new IRP model is built based on the existing Periodic Vehicle Routing Problem with Time-windows (PVRPTW). The model will be referred to as the Integrated Inventory and Periodic Vehicle Routing Proble...
