Abstract. This paper presents a survey of the research on the vehicle routing problem with time windows (VRPTW). The VRPTW can be described as the problem of designing least cost routes from one depot to a set of geographically scattered points. The routes must be designed in such a way that each point is visited only once by exactly one vehicle vehicle routing problem with time windows algorithm Rinnooy Kan and Trienekens extend the shortest qpath relaxation algorithm for the vehicle routing problem (Christofides, Mingozzi and Toth 1981b) to the VRPTW. With no branching required to obtain the solution of a four vehicle, 14 customer problem, the algorithm took 0. 58 minute of DEC 2060 CPU time.
Over the past 20 years vehicle routing problem with time windows has been an area of research that has attracted many researchers. In this period a number of papers have been published on the exact, heuristics and metaheursitics methods of the routing problem with time windows. vehicle routing problem with time windows algorithm
Each vehicle starts from the This Vehicle routing problem with time windows depot, arrives at the customers location, and returns back to (VRPTW) is an optimisation problem which has attracted a the depot, this direction will be considered as route. How can the answer be improved? May 01, 2010 The vehicle routing problem with multiple use of vehicles is a variant of the classical vehicle routing problem. It arises when each vehicle performs several routes during the workday due to strict time limits on route duration (e. g. , when perishable goods are transported). vehicle routing problem with time windows algorithm
