Performance of containers? flow at yard represents very important point of container terminals. The organization of container transport and stacking policies leads to less congestion and lower costs. Otherwise, containers wait in queue before they are serviced. This study presents an analytical approach for obtaining the average number of containers in queue. We proposed two models (constant and geometric) of bulk arrival multi-server queuing system. Traffic intensity and utilization factor are very important parameters that consist of data for arrival and service rate and number of servers (yard cranes). In this paper, we assume that there are three yard cranes that operate at container yard. A given numerical example for two models will improve the best values for performance of containers? flow at container yard.
