Simulation of Naval Training Pipelines

Flow of enlisted Navy men through basic training, BEE school and A school was simulated using SLAM. Queuing for courses, pass, setback and failure of students, and the limitation of resources in the BEE schools were modeled for variable numbers of A courses and enlisted student ratings. A travel delay between schools was modeled as a direct step function of the distance involved. For each course modeled, data included course duration, interconvening time between classes, minimum and maximum class sizes, pass, failure and setback rates, and the time, measured from the beginning of the simulation, when the first class is to convene. For each rating modeled, data included course sequence information (variable number of courses and school sequences), the number of that rating expected to report to basic training for the entire Navy each year for up to five years, the fractions of that total which report to each of three bases for basic training, the fractions which report each month, and the fractions which report each day of the week. Fleet returnees are modeled to enter the system as an across-the-board percentage of all basic training graduates. Output for each course included average, maximum and current queue lengths; standard deviation of the queue length; average waiting time in the queue for the course; total numbers of students who had started, failed, passes, and been setback in the course; and the number who were under instruction at the time the report was written. Output for each rating included a list of the A courses taken, numbers of regular recruits and fleet returnees who had completed training, and average times required to complete training, with optional histograms. A preliminary check was made for bottleneck situations before the simulation was started
