Abstract:
Abstract In this paper, the multi-depot heterogeneous fleet vehicle routing problem with time windows and assignment restrictions (m-VRPTWAR) is introduced. The problem addresses the assignment of a set of shipments to a set of freight routes so that unused cargo volume of the vehicles is minimized. The assignment of each shipment is restricted to a subset of the freight routes. Furthermore, the shipment has to be delivered in a specific time window. Thus, it is necessary to determine an order of the shipments of each freight route that guarantees the observance of all time windows. Firstly, a formulation of an integer linear program (ILP) for solving the m-VRPTWAR is developed and the problem is proven to be NP-hard. Afterwards, the ILP is evaluated by solving several large-scale scenarios using the solvers CPLEX and Gurobi.
