Waiting for commercial vessels inside the port is one of the most important problems facing traders and offshore companies, which often lead to material losses. The ports of Basrah are characterized by continuous congestion, which leads to the diversion of ships to the ports of the neighboring countries, causing the loss of many revenues to the country. This paper emphasizes the importance of non-preemptive priority queues (with multiple servers and multiple priority classes) to the problem of congestion of ports in order to promote sustainable development of the ports of Basrah. The aim of this paper is to apply a non-preemptive priority queues at ports of Basrah and calculating the average customer waiting time for the ships at berths.

This article provides an effective method to analyze the performance measures of non-preemptive fuzzy priority queues with unequal service rates. Here the arrival rate and the service rate are in fuzzy numbers. Using a new ranking method, the fuzzy values are reduced to the crisp values. For that cause, both the Triangular Fuzzy Number (TFN) and Trapezoidal Fuzzy Number (TpFN) are chosen to establish the proposal's effectiveness. An illustration is given to find the efficiency of the performance measures of the fuzzy queuing model.
