• W3171750356 abstract "Identifying the optimal technologies required for space architectures to fulfill needs of large and complex missions is difficult for three primary reasons. First, interactions between the involved systems and technologies cannot be easily identified. Second, the diversity of participating stakeholders and involved disciplines, and the multiple sources of information make the trade space large and difficult to navigate and analyze. Third, continuous progress in the field leads to the development of new technologies, for which data and models are likely to be scarce, thus contributing to increase the uncertainty. System-of-Systems methodologies can address these. Previous research focused on modeling and analysis of interactions between systems in the operational domain, to identify risks and criticalities. We apply similar methodologies to interactions between technologies in the developmental domain, with the goal of identifying potential bottlenecks and risks in the schedule of space missions. This approach supports decision-making for prioritization of technologies, accounting for technological needs of the mission, uncertainty in development time, potential delays, and changes in policies. A particular innovation is the design and use of artificial intelligent agents, that can recognize information coming from multiple sources, including documents in plain English, evaluate the relevance of documents for which they are trained, and recognize useful information in publications which are not strongly connected with the specific technology on which the agent has been trained. The results include development schedule of different architectures based on different technology prioritization and risk acceptance, analysis of the impact of delays and of changes in policies, analysis of flexibility of mission sets and a case study of Cryogenic Fluid Management technologies in an Artemis-based mission to the Moon is used to demonstrate the application of the methodology." @default.
