A SOLUTION OF BERTH ALLOCATION PROBLEM IN INLAND WATERWAY PORTS

This paper explores the impact of berth allocation problem (BAP) solving depending on different options for river port design. Comparing multipurpose and specialized berths layout with port efficiency requirements, based on berth allocation, an optimal design option may be selected. The aim is to achieve an optimal distribution of vessels alongside quay with minimum vessels' time in port and port operator workload. The model set up in this paper is tested on the example of the inland waterway port. The problem solution is attained using the linear mixed integer programming method. Standard assignment problem is adjusted in such a way to achieve the practical results in as low as possible mathematical iterations while not compromising results' precision.Original Abstract: U ovom radu istrazuje se utjecaj rezultata problema dodjele veza ovisno o razlicitim varijantama projekta rijecne luke. Usporedujuci postavu visenamjenskih i specijaliziranih vezova na temelju optimalnog pridruzivanja vezova plovilima, sa zahtjevima u pogledu efikasnosti luke, moguce je odabrati najbolju varijantu projekta. Cilj je postici optimalni raspored plovila uzduz pristana uz minimalno zadrzavanje plovila u luci i minimalni utrosak prekrcajnih resursa. Model osmisljen u ovom radu testiran je na primjeru luke unutarnjih voda. Za rjesavanje problema koristena je metoda linearnog programiranja u sklopu koje je posebno razraden i prilagoden problem asignacije na takav nacin da se dobiju prakticni rezultati u sto manje matematickih iteracija uz prihvatljivu tocnost rezultata.
