What is vehicle routing Problems with Time Windows?
Vehicle routing problem with time windows (VRPTW) can be defined as choosing routes for limited number of vehicles to serve a group of customers in the time windows. Each vehicle has a limited capacity. It starts from the depot and terminates at the depot. Each customer should be served exactly once.

What is pickup and delivery problem?
In the General Pickup and Delivery Problem (GPDP) a set of routes has to be constructed in order to satisfy transportation requests. Each load has to be transported by one vehicle from its set of origins to its set of destinations without any transshipment at other locations.
What is vehicle routing software?
Vehicle routing and scheduling (VRS) software is used by transportation companies to create the most optimal routing solutions for drivers and trucks in their fleets. These tools are used to increase control for managers in the transportation, distribution, or transfer of materials and products.
What is open vehicle routing problem?
In the open vehicle routing problem (OVRP), a vehicle does not return to the depot after servicing the last customer on a route. Contractors who are not employees of the delivery company use their own vehicles and do not return to the depot.
What is dynamic vehicle routing problem?
The Dynamic Vehicle Routing Problem (DVRP) is one of the important variants of VRP. Its aim consists in designing the optimal set of routes for a fleet of vehicles in order to serve a given set of customers while new customer orders arrive during the performance of the planned earlier work day.
What is capacitated VRP?
The capacitated vehicle routing problem (CVRP) is a VRP in which vehicles with limited carrying capacity need to pick up or deliver items at various locations. The items have a quantity, such as weight or volume, and the vehicles have a maximum capacity that they can carry.
What is the delivery problem?
The problem we introduce in this paper, the delivery problem (DP), calls for the identification of a set of routes visiting all customers, such that the expected number of successful deliveries is maximized. The DP is similar in nature to the team orienteering problem (TOP) (Chao et al., 1996).
What is dial a ride problem?
The Dial-a-Ride Problem (DARP) consists of designing vehicle routes and schedules for n users who specify pickup and delivery requests between origins and destinations. The aim is to plan a set of m minimum cost vehicle routes capable of accommodating as many users as possible, under a set of constraints.
What is vehicle routing in logistics?
Vehicle Routing Problem focuses on determining optimal routes for a fleet of vehicles given operational constraints like time window, route length, etc. It helps fleet managers plan routes that can maximize the efficiency of the fleet and minimize the last-mile delivery costs.
How does vehicle routing and scheduling software support logistics processes?
Vehicle routing systems help transport managers plan and optimise their daily vehicle routes, enabling them to reduce both fuel costs and fleet size. Automatically schedule an efficient set of vehicle routes to serve delivery points. Model routes using real road networks, provided by the Graphhopper project.
What is the problem with capacitated vehicle routing?
The items have a quantity, such as weight or volume, and each vehicle has a maximum capacity that they can carry. The problem is to pick up or deliver the items with the least cost, while never exceeding the capacity of the vehicles.
Which is an example of a CVRP problem?
It generalizes the well-known traveling salesman problem (TSP). There are many variants of vehicle routing problem. Some popular examples are as follows: CVRP (Capacitated Vehicle Routing Problem) : Vehicles have a limited carrying capacity of the goods that must be delivered.
Are there restrictions on number of routes in CVRP?
In the CVRP competition, it will be assumed that there are no restrictions to the number of routes in a solution. The most complete and up-to-date information for the CVRP competition is contained in the following document:
What is the input to the CVRP matrix?
Input to the CVRP consists of n locations (a depot and a set of n −1 customers), an n × n symmetric matrix D specifying the distance (or some other cost) to travel between each pair of locations, a quantity qi that specifies the demand for some resource by each customer i, and the maximum quantity, Q, of the resource that a vehicle can carry.
