A study examines the effects of erroneous estimation of activity durations on 2 different approaches for executing a resource-constrained project. The 2 approaches are scheduling and dispatching. The results show that scheduling generally produces a shorter project completion time than the heuristic dispatching rules. Results also indicate that project environment affects only the relative performance differences of the scheduling and dispatching rules but not their ranking. Frequent rescheduling improves the project completion time, while the timing of rescheduling has little impact on the improvement in the project completion time.
