  7. Abstract:
  8. The purpose of this thesis is to obtain a logical decision making for the landing of multiple electric vertical takeoff and landing (eVTOL) aircraft that are simultaneously approaching a skyport. This research was conducted in response to the expansion of cities and the increased demand for transportation. In fact, the increase in population in cities makes the existence of a new mode of air transportation unavoidable, and in this regard the landing and take-off of such aircraft is very important because using a control tower for managing the take-off and landings of these aircraft doesn’t seem possible. To do this, the problem of simultaneous landing of multiple eVTOL aircraft was divided to two parts: landing site selection and optimization of the landing path. The problem was solved while applying the safe distance constraint between aircraft and considering the optimal choice of landing site at the same time. The logic of game theory has been used to select the landing site, which is applicable to multi-agent decision making modeling. For path optimization GPOPS toolbox was used in MATLAB software which uses collocation and mesh refinement methods. In this study, we have shown how game theory can be used to manage the simultaneous landing of several eVTOL aircraft. The results show that using this logic can help decentralize these aircraft, and the results guarantee travel safety
