In this paper, the stochastic location-routing-inventory problem is considered in which retailers’ demands and lead-times are stochastic. Demand quantities follow Poisson distribution and lead-times are functions of the shortage quantity. It is also assumed that both retailers and distributors hold inventory and follow (S-1, S) inventory policy. According to these assumptions, we use METRIC (i....

One of the most important points in a supply chain is customer-driven modeling, which reduces the bullwhip effect in the supply chain, as well as the costs of investment on the inventory and efficient transshipment of the products. Their homogeneity is reflected in the inventory-routing problem, which is a combination of distribution and inventory management. This paper considers a multi object...

Troop movement involves transporting military personnel from one location to another using available means. To minimize damage enemies, the simultaneously uses reconnaissance and transportation units during troop movements. This paper proposes a vehicle routing problem considering (VRPCRT) for wartime The VRPCRT is formulated as mixed-integer programming model minimizing completion time of move...

Logistic activities, from a certain point of view, are often structured around two concepts, the transportation of goods and the management of the same goods. Of course, these two activities are highly interlinked. It is possible to combine at the same time the problem of defining the amount of goods that have to be shipped (the Inventory Management problem – the quantity decision) and the rout...

Electrified transportation and power systems are mutually coupled networks. In this paper, a novel framework is developed for interdependent power and transportation networks. Our approach constitutes solving an iterative least cost vehicle routing process, which utilizes the communication of electrified vehicles (EVs) with competing charging stations to exchange data, such as electricity price...

Reliable location routing problem considers a location problem and a vehicle routing problem in order to select the optimal location of facilities and at the same time the optimal routes for vehicles considering the unexpected failure for facilities in which, all facilities may fail with a probability. In this paper, a bi-objective mathematical model has been developed to minimize the total cos...

It is often very challenging to plan expedient and cost-effective operations for service trucks under network design constraints, particularly on congested urban roadways. Hence, it is beneficial to simultaneously account for truck facility location design and network expansion decisions to mitigate the additional congestion caused by trucks and facilitate their routing. This paper develops an ...

A typical Vehicle Routing Problem (VRP) is to design the least cost routes for a vehicle fleet to supply goods from inventory to demanding customer locations. In this paper, we are interested in routing vehicles to minimize unmet demand and time delays. An important application of the presented model is to distribute medical supplies to response to large-scale emergencies, such as natural disas...

In many logistic systems for less than truckload (LTL) shipments, transportation of goods from one origin to its destination is made through collection tours to a hub and delivery tours from the same or another hub, while the goods are shipped between two hubs using Full Truckload (FTL) shipments. Therefore, managers need to determine the location of the hubs, the allocation of non-hub nodes, a...
