The proper selection of statistical distributions is important for modeling port operations using simulations or
queuing theory. The aim of this study was to determine the appropriate statistical distributions for modeling
random processes related to ship operations in ports, including ship arrivals, berthing maneuver processes,
service processes, and unberthing maneuver processes. A literature review was performed on the statistical
distributions used in these random processes. In addition, the port data on ship operations gathered from three
different ports in Turkey were examined. Goodness of fit tests were conducted to determine the appropriate
distribution for each process.
