متن کاملOnline vehicle routing problems
The Traveling Salesman Problem (TSP) is maybe the archetypical problem in combinatorial optimization. This problem and its generalizations, vehicle routing problems, have been studied for more than thirty years; two entire monographs are devoted to the subject [34, 26]. Since the TSP is NP-hard, polynomial-time approximation algorithms are usually studied. However, usually the approaches to the...
متن کاملSTOCHASTIC VEHICLE ROUTING PROBLEMS WITH SIMULTANEOUS PICKUP AND DELIVERY SERVICES
The problem of designing a set of routes with minimum cost to serve a collection of customers with a fleet of vehicles is a fundamental challenge when the number of customers to be dropped or picked up is not known during the planning horizon. The purpose of this paper is to develop a vehicle routing Problem (VRP) model that addresses stochastic simultaneous pickup and delivery in the urban pub...
متن کاملAgents towards vehicle routing problems
A multi-agent VRP solver is presented in this paper. It utilizes the contract-net protocol based allocation and several improvement strategies. It provides the solution with the quality of 81% compared to the optimal solution on 115 benchmark instances in polynomial time. The self-organizing capability of the system successfully minimizes the number of vehicles used. The presented solver archit...
