As air traffic congestion grows, ground-holding of aircraft is becomingincreasingly common. The "ground-holding policy problem" (GHPP) is todecide which flights should be delayed on the ground before take-off andby how much, in order to minimize the cost of delays. This study is the first attemp to address the single- airport GHPP whiletaking into account the equality among various types of aircrafts. Bothdeterministic and stochastic versions of GHPP are discussed and solvedstatically in this study. Two integer programming models are formulated.These models try to minimize total costs while satisfying the constraintsof airport capacity and network effects. The total costs include airbornefuel cost, ground fuel cost, passenger cost, and penalty cost. The penaltyis for adjusting the equality explicitly. A heuristic algorithm is developed and tested. The results show that thesolutions obtained by the heuristic algorithm are very close to the exactones. The computation time, however, is significantly reduced by using theheuristic algorithm. A case study of the GHPP for Sungshan airport is conducted. Three differentcapacity scenarios, normal condition, switching to Runway 28, and airportclosing, are analyzed. We discuss the performance of the GHPP with and withoutthe consideration of equality compared to the "passive" strategy of no ground- holding. A sensitivity analysis for various penalty costs and airborne costsis conducted.The numerical results indicate that the ground-holding policy can effectivelyreduce the total costs. The model with the consideration of equality is usefulfor improving the fairness of delay distribution among various types ofaircrafts. Current air traffic flow management strategy is also compared withthe one developed by the GHPP.
