capacitated multi-depot vehicle routing problem with inter-depot routes
in this paper, we study the multi-depot vehiclerouting problem with inter-depot routes, in which the vehicles can replenish atintermediate depots. vehicles leave the origin depot with load on-board andserve customers until out of load. they may visit an intermediate depot toreplenish and finally return to the origin depot, completing their route. weinitiate a mathematical mixed integer programm...
متن کاملThe Multi-Depot Vehicle Routing Problem with Inter-Depot Routes
This article addresses an extension of the multi-depot vehicle routing problem in which vehicles may be replenished at intermediate depots along their route. It proposes a heuristic combining the adaptative memory principle, a tabu search method for the solution of subproblems, and integer programming. Tests are conducted on randomly generated instances.
متن کاملDevelopment of Model and Algorithm for Depot Balancing Multi-Depot Vehicle Scheduling Problem Considering Depot Balancing
The main of multi-depot vehicle scheduling problem (MDVSP) is to schedule the timetabled trips using limited resources, optimally. The problem is very important in the management of the transportation systems. One of the most useful ways to better manage these systems is to consider the real conditions including depot balancing constraints. To normalize the number of vehicles departed from each...
متن کاملA HYBRID ALGORITHM FOR THE OPEN VEHICLE ROUTING PROBLEM
The open vehicle routing problem (OVRP) is a variance of the vehicle routing problem (VRP) that has a unique character which is its open path form. This means that the vehicles are not required to return to the depot after completing service. Because this problem belongs to the NP-hard problems, many metaheuristic approaches like the ant colony optimization (ACO) have been used to solve OVRP in...
متن کاملVehicle Routing Problem with Multi-depot and Multi-task
This paper presents a new mathematical model of the vehicle routing problem in the context of city distribution, which considers multi-depot, multi-model vehicles and multi-task. The objective function includes three parts: transport cost, deadheading cost and time cost. To solve this mathematical model, a self-adaptive and polymorphic ant colony algorithm (APACA) has been introduced. Finally, ...
