The DAKOTA scheduling system has been proposed for use in the United States Air Forces Europes USAFEs Operational Support Airlift OSA scheduling. This thesis examines the OSA scheduling topic and reviews the relevant literature on vehicle routing, concluding that exact methods are intractable for large problem sizes. Consequently, heuristic methods must be considered. This thesis takes a detailed look at the DAKOTA heuristic. It examines the concepts of Validation, Verification and Accreditation VVA, particularly as they apply to heuristics and algorithms. It then defines what measures of performance may prove useful in judging heuristics and algorithms in general, and details the statistical tests which can be used to make those comparisons. It discusses four of the predominant airlift scheduling models currently in use, and finally develops a methodology which can be used to evaluate a deterministic passenger airlift scheduling heuristic, using DAKOTA as a case study.
