RT Journal Article SR Electronic A1 Matas, Martin A1 Novak, Andrej T1 Models of Processes as Components of Air Passenger Flow Model JF Communications - Scientific Letters of the University of Zilina YR 2008 VO 10 IS 2 SP 50 OP 54 DO 10.26552/com.C.2008.2.50-54 UL https://komunikacie.uniza.sk/artkey/csl-200802-0009.php AB The paper presents the model of air passenger processes at airports for single source and two source processes. It shall be used as a component for the development of passenger flow model. In the paper the single source model is applied on passenger check-in process. It is based on deterministic queuing model where cumulative diagrams of the flow are used for calculations. As input data the model requires the arrival and service profile of passengers at the check-in. The arrival profile is a cumulative number of passengers arriving to the server during the time. The service profile is a cumulative number of passengers which can be served by the check-in process. The calculation of average waiting time and average length of the waiting queue is presented in the paper. In latter part of the paper the case of two source process is discussed.
