Portsareconsidered asthe connection pointsof the world tradeinallmaritime countries. Hence, issue such aswaiting times andservicetimesof thevessels are considered very importance. On this basis of this in the congestedports, loading and unloading of vessels may take months in the queues due to the lack of loading facilities.In fact ports are considered as a queuing system characterized with basic parameters: the vessels arrival rate and the ship service at an observed unit of time.The appropriate indices of the port operations are computed on the basis of these parameters. Thisresearchhas described theapplication ofqueueing theoryfor improving theport'soperationsin order to reducewaiting timesof the vessels. On the basis of this study, it can beconclude thatqueuing theorycandeterminethe appropriateinputpattern, analysequeuingsystems, and reducewaiting times of vesselsreadyto be served in order to increase the throughput ofports.
