dc.description.abstractPojam specifiičnog odnosa troškova odnosi se na razne tipove troškova broda i luke modelirane kao sistem reda čekanja Koristeći poznatu opštu formulu za specifični odnos troškova (označen sa R), izvodimo odgovarajući izraz za R u odnosu na M/Ek/1 model reda čekanja, gde je Ek (k = 2,3,...) Erlangova k - raspodela verovatnoće. Ovaj izraz nam omogućava da dobijemo teorijski rezultat koji se može primeniti za određivanje optimalnih vrednosti parametra oblika k od Ek uz data ograničenja u odnosu na druge performanse razmatranog lučkog modela teorije redova čekanja. Takođe su predstavljeni odgovarajući numerički i grafički rezultati. Dobijeni rezultati bi mogli biti korisni za buduća istraživanja razmatrane problematike.sr
dc.description.abstractThe notion of specific cost ratio involves different type of costs of a ship and a port modeled as a queueing system. Using the known general formula for the specific cost ratio of arbitrary port queueing system (denoted as R), here we derive the related expression for R of the M/Ek/1 queue, where Ek (k = 2,3,...) is the Erlang- k probability distribution. This expression allows us to obtain a theoretical result which can be applied for determining the optimal values of shape parameter k of Ek under given constraints on other performances of the considered port queueing system. The related numerical and the graphical results are also presented. The obtained results would be a useful tool in future research in related subject areas.en
