In the recreational vehicle rental business, the problem of preparing a schedule for each vehicle in the fleet (by assigning accepted bookings to available vehicles over the planning horizon) is known as the recreational vehicle scheduling problem (RVSP). The problem belongs to the class of minimum cost multicommodity network flow problems which is known to be NP-hard. A formulation of the RVSP from...
This paper presents a new hybrid heuristic combining particle swarm optimization with a Lagrangian heuristic along the lines first proposed by Wedelin. We will refer to this as a Combinatorial Lagrangian Particle Swarm Optimization Algorithm (CoLaPSO). It uses a problem representations that works simultaneously in the dual space (Lagrangian multipliers) and the primal space in the form of cost perturbations...
