The paper presents an approach to this type of problem. Was submitted the general approach to construct the model and presented selected aspects of the application AIRS enabling decision making support on minimizing taxiing aircraft at take-off and landing operations. Taxiing operations of aircraft on the apron are the binding part of planning and air traffic control phase including the sequencing of arrivals and departures, planning of air traffic in the immediate vicinity of the airport and issues of passenger traffic in the terminals and ground handling of aircraft. The airport is presented as a model which was implemented in the form of a computer application AIRS. Application AIRS is suported to determine the optimal taxiways on schedule. The procedure for decision support in carrying out the operation of aircraft consists of: data on the types of aircraft, data staging aircraft, data about the time of use of the types of aircraft, technical and organizational parameters of the process taxiing, the structure of the apron to the process of taxiing, routing algorithms of landing aircraft, routing algorithms of taking off aircraft, algorithms for taxiing in other cases.
