Abstract

We report on a method that usesspatio-temporal reasoning to schedule aircraft to take-off positions.The objective is to aid human controllers to detect potentialconflicts which could cause hazards or delays. The challengeis to develop temporal-spatial reasoning systems that can handlecomplex and dynamic situations so that their results help thecontrollers to instruct the aircraft to move smoothly until theytake off. Optimisation is secondary and sometimes not easy tomeasure. Although the proposed method was developed with theaircraft domain in mind, it could be applied to order the movementsof interacting objects that have both expected paths and destinationtimes (i.e., ’’achieve this goal, at this place, at this time‘‘).
