In this research work an analytical model has been proposed, for finding new distribution passage from the suppliers to the geographically scattered dealers and to deal with the pricing problem. Since the result for this model is a non-polynomial problem, tabu search that uses various surrounding approaches has been employed to provide gratifying results. Rate fixing and request claiming are ne...

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...

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...

in the case of hazardous materials management, selected routes for carrying hazardous materials (i.e.,hazmat) have significant effects on locating hazmat distribution centers. since, risk and cost are usuallyconsidered as two main attributes to determine the best routes, optimized locations are sequentially outlineddepending on selected routes. in the present paper, two different approaches of ...

We consider a single item Production-Inventory-Routing problem with a single producer/supplier and multiple retailers. Inventory management constraints are considered both at the producer and at the retailers, following a vendor managed inventory approach, where the supplier monitors the inventory at retailers and decides on the replenishment policy for each retailer. We assume a constant produ...

The Two-Echelon Routing Problem constitutes a class of combinatorial optimization problems with applications in many different fields such as city logistic planning, intermodal transportation, postal and parcel delivery distribution systems and so on. This thesis contains: a survey of the main contributions related to the two-echelon routing, focusing on the Two-Echelon Location Routing Problem...
