Increasing interest has been devoted to Planning as Heuristic Search over the years. Intense research has focused on deriving accurate heuristics in polynomial computational time for domain-independent planning. This paper reports on an extensive survey and analysis of research work related to heuristic derivation techniques for state space search planning, as well as other planning paradigms. ...

Background The concept of decision space holds appeal as an approach to disaggregating the elements that may influence decision-making in decentralized systems. This narrative review aims to explore the functioning of decision space and the factors that influence decision space.   Methods A narrative review of the literature was conducted with searches of online databases and academic journals ...

To build a sustainable space transportation system for human exploration, the design and deployment of infrastructure, such as in situ resource utilization plants, in-orbit propellant depots, on-orbit servicing platforms, are critical. The analysis trade studies these space-infrastructure systems require consideration not only infrastructure elements themselves, but also their supporting (e.g.,...
