Improved Particle Swarm Algorithm to Solve the Vehicle Routing Problem

Vehicle routing problem is a NP hard problem. To solve the premature convergence problem of the particle swarm optimization, an improved particle swarm optimization method was proposed. In the first place, introducing the neighborhood topology, defining two new concepts lepton and hadron. Lepton are particles within the scope of neighborhood, which have weak interaction between each other, so t...

An algorithm for the vehicle routing problem with stochastic demands

Motivated by the fixed routes problem, where the objective is to design a set of routes to be operated unchanged over a period of time, we study the vehicle routing problem with stochastic demands. An algorithm is developed based on a stochastic programming model with recourse. Computational experiments show that the algorithm compares favorably to existing algorithms. This research was support...

Competitive Vehicle Routing Problem with Time Windows and Stochastic Demands

The competitive vehicle routing problem is one of the important issues in transportation area. In this paper a new method for competitive VRP with time windows and stochastic demand is introduced. In the presented method a three time bounds are given and the probability of arrival time between each time bound is assumed to be uniform. The demands of each customer are different in each time wind...

A particle swarm optimization method for periodic vehicle routing problem with pickup and delivery in transportation

In this article, multiple-product PVRP with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. A mathematical formulation was provided for this problem. Each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. To solve the problem, two meta-heuristic methods...
