Intelligent preemption in construction of a manmade island for an airport

This paper presents the simulation model and 3D animation for a project involving large-scale undersea land reclamation for the construction of a manmade island for an airport. The model illustrates how intelligent preemption can be dynamically used at simulation runtime to enforce the operational policies of a tug boat that guides barges loaded with earth into the island for unloading and then out into the sea after unloading is complete. The example also investigates the repeated stalling of the otherwise continuous unloading operations due to the need to share the narrow island entrance channel with watercraft supporting other construction activities. The solution to this problem is out-lined conceptually using the activity-scanning modeling paradigm. The solution is described in detail using a simulation model developed in STROBOSCOPE and a 3D animation created using VITASCOPE.
