The effect of intermittent work patterns on the costs of ship repair and maintenance were modeled for one San Diego shipyard for proposal development purposes. The system dynamics model allows the shipyard to experiment with different patterns of work, availability schedules, hours, repair availability length and start dates to determine the overall loading of the shipyard's seventeen trades and four skill levels. Important factors considered are volume, productivity, experience, man-day rate and error rate in generating validated estimates of work to be scheduled, actual work accomplished, workforce used and the cost to the government. The model is still in use and has been updated annually since its inception in 2003.
