Abstract: This paper makes use of partial solutions to solve a two-echelon heterogeneous truck fleet distribution model with single-sourced distribution centres. The partial solutions are predetermined using an algorithmic procedure that determines the mix of trucks to deploy to a demand point by relating the required shipment volume to the cost and capacity of each truck type. The partial solutions reduce the feasible region of the associated mixed-integer programming model, which is then solved to obtain the complete solution. A computational study demonstrates that solutions for prototypical two-echelon distribution scenarios with up to 32 distribution centres and 1,600 demand points can be obtained within a few seconds of computation time.
