The aim of this paper is to determine the optimum number of truck processing booths in the BIK dry-bulk terminal entrance gate, to reduce the associated truck congestions. The queuing theory has been used to gain this purpose. Since, the queuing theory is one of the appropriate methods to study traffics and congestions. The necessary data to analyze system performance analysis factors and to determine the pattern of inter arrival and service times are collected by several field studies. Descriptive statics showed, both inter arrival and service times follow exponential distribution. Then, the M/M/s queuing model has been developed for this port. Further, the K-S and χ2 goodness of fit tests has also demonstrated the suitability of model development. Then, the related system performance measurements have been determined. The performance measurements analysis showed a very high sensitiveness for this system and every change in the number of servers caused great impact on the system utilization and performance.
