This paper sets out to investigate the impact of the taxiways' status on airport operations. The main objective is to create a quantifiable method to measure the research project's consequences e.g. a modeling tool. The main findings will be the measurable impact/consequences of maintenance activities on different stakeholders. A simulation is developed and used to test and optimize certain scenarios with a validation carried out at Schiphol airport, Amsterdam. It will show that the simulation tool is an effective way of optimizing taxiway system maintenance so that impact on airport operations is minimized in terms of performance and ideally, the total value to the airport operator. In general, the full paper will aim to explore the possible financial benefit for operators, the optimization between work-costs en fuel-costs, and the optimization between costs and capacity; in order to explore the potential the tool has as an analysis and decision making tool.
