This research develops a mathematical model for improving runway's capacity using landing re-sequencing approach. The case study Suvarnnabhumi airport isapplied. The objectives of this study are to (1) study the factor causing delay of arrival traffic at Suvarnnabhumi airport, (2) develop a mathematical model for re-sequencing of landing aircraft in the final approach phase to maximize the runway capacity and (3) apply the result of study as a tool to improve planning strategy for the air traffic controller in the future. The data used in this ...
