Query: Multi-Fidelity Space Mission Planning and Infrastructure Design
  Framework for Space Resource Logistics   To build a sustainable and affordable space transportation system for human
space exploration, the design and deployment of space infrastructures are
critical; one attractive and promising infrastructure system is the in-situ
resource utilization (ISRU) system. The design analysis and trade studies for
ISRU systems require the consideration of not only the design of the ISRU plant
itself but also other infrastructure systems (e.g., storage, power) and various
ISRU architecture options (e.g., resource, location, technology). This paper
proposes a system-level space infrastructure and its logistics design
optimization framework to perform architecture trade studies. A new space
infrastructure logistics optimization problem formulation is proposed that
considers infrastructure subsystems' internal interactions and their external
synergistic effects with space logistics simultaneously. Since the full-size
version of this proposed problem formulation can be computationally
prohibitive, a new multi-fidelity optimization formulation is developed by
varying the granularity of the commodity type definition over the network
graph; this multi-fidelity formulation can find an approximation solution to
the full-size problem computationally efficiently with little sacrifice in the
solution quality. The proposed problem formulation and method are applied to a
multi-mission lunar exploration campaign to demonstrate their values.
