Queuing theory in the analysis of the container terminal Brajdica operations

Tema rada je izračun potrebnog broja vezova na kontejnerskom terminal Brajdica u riječkoj luci. Nakon povijesnog pregleda razvoja terminala naveden je trenutni koncesionar sa kratkim pregledom poslovanja i djelatnosti. Teorija redova čekanja je metoda koja se koristi u ovom radu za dokazivanje postavljene hipoteze da terminal raspolaže dovoljnim prihvatnim kapacitetima s obzirom na količinu prometa. Navode se osnovne teorijske postavke metode sa ispisom potrebnih formula korištenih u izračunu. Prikupljanje podataka o prometu brodova i o duljini vremena provedenog na vezovima, pretpostavka je za provođenja izračuna za tri varijante različite po broju vezova. Analiza dobivenih rješenja ukazuje na funkcioniranje terminala ovisno o broju vezova te koja je varijanta optimalna s obzirom na postavljeni kriterij.The topic of the paper is the calculation of the required number of berths at the Brajdica container terminal in the port of Rijeka. After a historical overview of the development of the terminal, the current concessionaire is listed with a brief overview of operations and activities. Queue theory is the method used in this paper to prove the hypothesis that the terminal has sufficient reception capacity with respect to the amount of traffic. The basic theoretical settings of the method with a printout of the required formulas used in the calculation are given. Collecting data on ship traffic and the length of time spent on berths, is a prerequisite for conducting calculations for three variants that differ in the number of berths. The analysis of the obtained solutions indicates the functioning of the terminal depending on the number of berths and which variant is optimal with regard to the set criteria
