Temporary gate shortages and stochastic flight delays (including late departures or arrivals and early arrivals) are common problems that often occur simultaneously in real-time airport operations. The aim of this paper is to design a gate reassignment model to deal with temporary gate shortages and stochastic flight delays. This is done by allowing the violation of gate reassignment constraints in the model. A numerical test was carried out, based on data from the operations of the Taiwan Taoyuan Airport (a major international airport in Taiwan), to demonstrate the performance of the proposed model. A comparison of the proposed model and a traditional reassignment model, as well as major findings related to the test results, are also discussed and presented. [ABSTRACT FROM AUTHOR]
