The vehicle routing problem vrp optimizes the routes of delivery trucks cargo lorries public transportation buses taxis and airplanes or technicians on the road by improving the order of the visits. Iii the goal is to compute a set of routes that minimizes. The objective is to find a set of.

The vehicle routing problem vrp is one of the most challenging combinatorial optimization task. Often the context is that of delivering goods located. Ii each task requires a certain amount of on site service.

It generalises the well known travelling salesman problem. F urthermore a real life instance of the dynamic vehicle routing problem originating from the pick up s and deliveries of long distance courie r mail is examined using the al gorithm proposed to. I a team of m vehicles is required to service a set of n static tasks in a metric space.

This routing optimization heavily reduces driving time and fuel consumption compared to manual planning. Theres actually already many well known heuristics and algorithms that can solve the static vehicle routing problem vrp but its tough to tell how well some of these translate to the. Problem and have concluded that practically all the vehicle routing problems are np hard among them the classical vehicle routing problem since they are not solved in polynomial time.

The vehicle routing problem vrp is a well kn own problem in operational research where customers of know n demands are suppli ed by one or several depots. Dvr problems represent the dynamic counterpart of the well known static vehicle routing problem vrp whereby. T he vehicle routing problem vrp is a combinatorial and integer programming which ask what is the optimal set of routes for a fleet of vehicles in order to deliver to a given set of customers.
