JRG-A1 - Overall System Evaluation

Shaping the necessary transition pathways to achieve sustainable air transport solutions requires a sound understanding of the behavior of the air transport system itself. The task of the group is to analyze and evaluate alternative transition pathways in order to achieve long-term development goals for the air transport system.

Objective

• Analyze and evaluate the overall system behavior of the ATS
• Simulating air traffic with appropriate functional scope
• Managing complexity of the ATS
• Considering multiple uncertainties

We have made our model to describe the ATS development for battery-operated aircraft available. An algebraic description of the model can be found as well.

Current Topics for Student Theses

System Dynamics Modeling of Market Entry and Exit Strategies of Airlines

This master thesis should implement a System Dynamics modeling of Market Entry and Exit Strategies of Airlines. This includes the determination of the corresponding system borders, the implementation in VenSim, and  testing and interpreting of the results.

It would be helpful to have some experience wih System Dynamics beforehand.
