This paper proposes a methodology for sizing certain large-scale systems of reusable, capacity-constrained resources engaged in tasks of varying duration. A heuristic program schedules resources throughout a finite planning horizon using two decision variables: varying resource capacity for meeting demand and varying task duration. A model of the problem and heuristic scheduling program are presented. A sequential, iterative sizing procedure determines the number of system resources to meet demand at each stage of the problem. Results compare the methodology with heuristics used in practice to schedule resources and size a real-world, large-scale training system.
