Abstract
The Queuing theory plays an important role in solving the basic problems in every vital fields as production system, transportation systems with all its kinds: airway, naval, land and also all economics systems. This study contains some important methods in queuing theory, and to reach a solution that treated the problem, the researcher exposed some economic indication related to the problem under study, which show that the average period of service is high. For this some basic systems and relations related to the queuing theory such as (MM1), and multiple (MMC) channels systems and the general system (GG1) and (GGC) and variety of distributions are used. In application this contains very important conclusions to reduce the cost of waiting in queue systems or congestion in some centers of the port and improving the service level for the general interest to insure the fire distribution of ships served in that centers.
