Sažetak
The paper demonstrates application of the queuing theory in modelling a port's bulk cargo unloading terminal. A bulk cargo terminal can be observed as a queuing system defined with basic parameters: the rate of bulk cargo ship arrivals or quantity of bulk cargo and the rate of ship servicing i.e. quantity of bulk cargo, in an observed time unit. Appropriate indices of bulk cargo terminal operations are computed on the basis of these parameters. The unloading terminal is determined as queueing system marked with M/M/1 by Kendall notation, System is characterized with Poisson distribution of entity arrivals and exponentially distributed service time. Subsequently, the model set up will be tested on the real example of the unloading terminal of the bulk cargo port in Bakar. Through application of the proposed model it should be possible to make decision on how to make optimization of the transhipment processes on a bulk discharging terminal to increase its efficiency. Obtained parameters and calculated indices point to solid capacity employment rate in 2005 and the probability that the berth is unoccupied is relatively low. Indices show that the terminal traffic rate has dramatically improved taking into consideration previous years.
