ShuttleOps - A Space Shuttle Ground Operations Discrete Event Simulation
The Shuttle operations simulation.
ShuttleOps is a discrete event simulation (DES) of the Space Shuttle ground processing operations, representing operations from the start of a launch flow through the return landing of the Shuttle orbiters. The DES was constructed using Arena Simulation, a software package from Rockwell Automation. A graphic user interface (GUI), pictured above, was also developed to provide an easier way of entering inputs into the underlying simulation. ShuttleOps was used to explore changes to the Shuttle ground operations processes, quickly providing insight into "what-if" scenarios such as changes in resources (such as the number of facilities or bays available, or vehicle fleet size), or off nominal probabilities, such as alternate launch site landings.
