Integration of Risk Sources and Risk Controls to SysML Requirements Diagrams With Application to Sustainable Aviation Fuels

Sustainable aviation fuel (SAF) is a critical component of decarbonization of the aviation sector, is a “drop-in” technology solution that has gained the attention of stakeholders in the supply chains of jet fuel (growers to airport terminus). The inability of past work to fit SAF supply chains into a single strategy has led to the complexity of fuel demand and has left airports to address programmatic risks regarding cost, transportation, negotiations, schedule, and environmental conditions. This study proposes an innovative approach integrating the concepts of STAMP methodology and risk analysis into SysML requirements diagrams (Systems Modeling Language), and demonstrates the new approach to evaluate the programmatic risk of SAF supply chains. This method supports risk assessment and management of business processes, contributing to awareness and preparedness of airport operators. The outcome of this research will contribute to a better understanding of the risk landscape and help stakeholders, particularly airport operators, navigate the challenges and uncertainties associated with adopting SAF. By tracking enterprise risks in a context of SysML requirements diagrams, airports can proactively implement mitigations, improve assurance protocols, optimize transportation logistics, streamline negotiations, enhance scheduling, and align with environmental considerations.
