Abstract:

A computer model which simulates the traffic flow of a Navy port has been developed. The model causes a ship to be placed in one of seven possible states on extended operation, in overhaul, at a tender, in port on normal operations, in port preparing for overseas movement, in port on 30-day stand down, or on short deployment on normal operations. Hotel utilities, which include steam and electric power, can be provided to a ship in port. A Monte Carlo method is used to determine the length of stay in any state. The model attempts to berth ships coming into port according to a pier-preference scheme. Input to the model includes a description of a ship and its cycle times, and a description of the pier in terms of its utilities and the ships it can berth. Computer output includes a summary of the time each ship spends in each state. The summary can be produced daily, quarterly, or for the entire simulation time of the run, which may be up to six years.
