ITIS 1P97 Sproule Fall 2011 Lab Workshop 4 – Simulation Fully loaded barges arrive at night in New Orleans following their long trips down the Mississippi River from industrial Midwestern cities. The number of barges docking on any given night ranges from 0 to 5. The probability of 0, 1, 2, 3, 4, or 5 arrivals is given in Table 1. A study by the dock superintendent reveals that because of the nature of their cargo, the number of barges unloaded also tends to vary from day to day. From 20 days of observations, the superintendent has collected the information in Table 2 from which we can create a probability distribution for the variable “daily unloading rate”.

Any barges that are not unloaded the day of arrival must wait until the following day. When barges are delayed for a day, the superintendent
