One of the important aspects of distribution optimization problems is simultaneously, controlling the inventory while devising the best vehicle routing, which is a famous problem, called inventory-routing problem (IRP). When the lot-sizing decisions are jointed with IRP, the problem will get more complicated called production inventory-routing problem (PIRP). To become closer to the real life p...

Although evolutionary algorithms have often been used to address VRPs and VRPTWs [1], applications to other routing problems such as period routing and inventory routing are less common. In this paper, a versatile hybrid evolutionary algorithm is developed that can be used for cyclic inventory routing and a variety of capacitated and periodic vehicle routing problems. First, a random insertion ...

Two types of decisions that directly affect the performance of a distribution system is the vehicle routing and inventory assignment. These problems have been studied separately for many years. The inventory routing problem (IRP) is integration of above mentioned distribution problems. In the other words, IRP assumes each customer maintains a local inventory of a product and consumes a certain ...

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...
