Abstract: This paper describes an efficient model for coordinating the logistics of emergency response activities that involve both deliveries and pickups. The proposed model is more efficient than previously published models. We show that the proposed model reduces the size of a recently published dynamic network flow model by a factor of T, where T is the length of the planning horizon. In the numerical results, we illustrate the trade-off among three objective functions that are managerially important: minimising total delay of deliveries and pickups, minimising total distance travelled and minimising the number of vehicles used in the operation.
