Today, one of the new technologies in the modern era is Vehicular Ad-hoc Network which has takenenormous attention in the recent years. Because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called V2V orvehicle to vehicle communication and vehicle to roadside infrastructure, called V2I. Designin...

The inventory routing problem involves trading off inventory holding costs at client locations with vehicle routing costs to deliver frequently from a single central depot to meet deterministic client demands over a finite planing horizon. In this paper, we consider periodic solutions that visit clients in one of several specified frequencies, and focus on the case when the frequencies of visit...

In this paper, we present a methodology for solving a multi-product, multi-depot periodic vehicle routing problem. The problem focuses on allocating products and assigning appropriate delivery days to a set of customers, and designing a set of delivery routes for every day of the planning period. A tabu-search based heuristic is proposed to find the best allocation and routing plan that would g...

vehicle routing problem (vrp) is one of the major problems in the transportation and distribution planning. in the most previous studies, the objective of vrp models was distance and vehicle related costs. however in many industrial cases along with routing distance, vehicle loading amount is a factor of cost function. in this paper, we formulate a mixed integer non-linear programming (minlp) m...

The purpose of this research is to present a new mathematical modeling for a vehicle routing problem considering concurrently the criteria such as distance, weight, traffic considerations, time window limitation, and heterogeneous vehicles in the reverse logistics network for collection of expired products. In addition, we aim to present an efficient solution approach according to differential ...

In recent years, great efforts have been made to reduce greenhouse gas emissions by vehicles. Petroleum products produces greenhouse gas emissions, therefore reducing the use of these products can make a major contribution to reducing pollution. The Fleet Size and Mix Vehicle Routing Problem is one of the most widely used routing branches. In this problem, there are vehicle with different capac...

In vehicle routing problems (VRPs) the decisions to be taken concern assignment of customers vehicles and sequencing assigned each vehicle. Additional may need jointly taken, depending on specific problem setting. this paper, after discussing different kinds in classes VRPs, class where decision about when routes start from depot has is considered related literature reviewed. This problems, tha...
