Optimizing airport stand allocation using multi-objective linear programming

Airport stand allocation is a multi-purpose optimization process that has an impact on operational efficiency and requires rapid intervention in case of changing conditions (e.g. managing delays in case of severe weather conditions), especially at busy airports. In our article, we model and optimize airport stand allocation, which is the scientific value. We present the process and the problem of airport stand allocation, with a special focus on factors influencing the allocation. We develop a linear programming model of stand allocation and define constraints and objective functions considering parking (stand usage) cost and passenger walking time, among others. A fictitious airport was modeled, and the stand allocation was optimized. Four weighting cases were examined. As a result of weighting, the allocation of stands can be optimized in several ways.
