This session seeks papers on the application of modelling, simulation and optimisation techniques to fleet sizing, scheduling and management problems within the field of Defence and Homeland Security. This includes the areas of: determining fleet size and fleet mix; operational mission scheduling & assignment; peacetime fleet scheduling & planning (e.g. flight & maintenance planning, ship mission scheduling, etc); crew training and assignment to missions or platforms; and logistics & supply chain modelling. Solution methods may include mathematical programming, heuristics, discrete-event simulation or other techniques amenable to Defence fleet management applications.
