The 'Hub' and 'Wheel' Scheduling Problems. Part 1. The 'Hub' Scheduling Problem: The Myopic Case.
Abstract
The problem is that of scheduling truck movement (loaded and empty) between a central depot (the hub) and a number of outlying cities. Current demand is known deterministically, but future demand is uncertain. The myopic case treats two periods only: the current period and one future period. The objective is to minimize the expected total operating penalty, consisting of the costs of moving empties and the costs of delaying shipments. In two special cases the procedure of solution reduces to simple marginal analysis. In the general case, a network flow model is proposed that is easily solved. Part II generalized the planning horizon to multiple planning periods, including the infinite horizon. Part III generalizes the problem to permit inter-city shipments (the wheel problem).
