The Gulf Shipping Company in Dubai, UAE, unloads cargo from ships arriving daily on a first-come, first-served basis. Ships that are not unloaded on the day they arrive are unloaded the following day. Nevertheless, ships that are waiting to be unloaded cost money. The arrival rates of ships and the daily unloading rates are random variables with no known probability distributions. The manager of the Port of Dubai wants to improve the efficiency of the waiting line system and decides to conduct a simulation study to analyze cargo ship arrivals, unloading of cargo, and delays that occur in the Port. Based on last year€™s data, the port manager has compiled the data given in the following table:

1. Conduct a 20-day simulation trial of ship arrivals and unloading of cargo.

2. Based on the simulation results, compute the daily average number of ship arrivals, daily average number of ships unloaded, and the average number ships waiting to be unloaded till the next day.
