オブジェクト指向言語を用いた空港における航空交通流のシミュレーション

抄録

Recently the demand of air transportation has been remarkably increased. However it is impossible to expand their facilities, because most of airports in Japan are located in the centers of great cities. This situation necessitates a new approach for air traffic control and the evaluation of a plan for the airport facilities, so that air traffic flow at the airport may be streamlined and maintained in order.
From this standpoint, a prototype simulation system for air traffic flow at airports with several runways is developed, using an object-oriented approach (Smalltalk-80). This paper presents a method of air traffic control which gives instructions so as to satisfy the safety constraints on distance and time separations between arriving and/or departing aircraft, taking account of various probabilistic fluctuations. The validity of the proposed system is demonstrated through examples.
