There are numerous practical vehicle routing applications in which vehicles have to stop at certain facilities along their routes in order to be able to continue their service. At these stops, the vehicles replenish or unload their cargo or they stop to refuel. In this paper, we study the Vehicle Routing Problem with Intermediate Stops (VRPIS), which considers stopping requirements at intermedi...

In this article, multiple-product PVRP with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. A mathematical formulation was provided for this problem. Each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. To solve the problem, two meta-heuristic methods...

Stochastic Approach to Vehicle Routing Problem: Development and Theories Abstract In this article, a chance constrained (CCP) formulation of the Vehicle Routing Problem (VRP) is proposed. The reality is that once we convert some special form of probabilistic constraint into their equivalent deterministic form then a nonlinear constraint generates. Knowing that reliable computer software...

This paper applies the elitist genetic algorithm to electric vehicle routing problem with time window. In initialization, proposes an improved neighbor initialization method for adaptive algorithm. The is used select nearest EV customer as next route be scheduled and make start from suitable first in of GA. It makes begins a neighboring directionality, which can inherited selection, crossover, ...

Abstract:Based on current energy storage technologies such as batteries and fuel cells, the inherent battery capacity of electric vehicles puts constraints their driving range requires charging in process completing tasks. In this paper, with practical application logistics industry background, from vehicle scheduling path planning, a hybrid algorithm combining genetic-particle swarm is propose...

An electric road system (ERS) is a in which vehicles can travel powered from the electrical grid. Deployed at scale, this technology reduces or eliminates need for (EVs) to stop recharging, and allows equipping these with smaller batteries. In particular, it facilitates decarbonisation of freight transportation. paper, we present routing problem hybrid vehicle travelling on ERS network, using e...

Manufacturers, who re-supply a large number of customers, continually struggle with the question of how to formulate a replenishment strategy. The purpose of this paper is to determine the optimal set of routes for a group of vehicles in the transportation network under defined constraints – which is known as the Vehicle Routing Problem (VRP) – delivering new items, and resolving the invent...

the location-routing problem is a relatively new branch of logistics system. its objective is to determine a suitable location for constructing distribution warehouses and proper transportation routing from warehouse to the customer. in this study, the location-routing problem is investigated with considering fuzzy servicing time window for each customer. another important issue in this regard ...

Electric vehicle routing problems (E-VRPs) are receiving growing attention from the operations research community. Electric vehicles (EVs) differ substantially from internal combustion engine vehicles. In the routing context, the main difference is due to the limited EV autonomy, which can be recuperated at charging stations. These are rather scarce, thus EVs typically have to perform detours t...
