The key objective of every structural design in extreme environments is to develop a structural system, which is able to fulfill its functional requirements in a highly economical way mainly due to initial transportation issues.
Many known conceptual lunar designs, for example, use global or partial safety factors to ensure the reliability of the structural members.

However, a suitable approach for traditional design on Earth is not necessarily considered appropriate for novel and unique structures such as lunar habitats.

Uncertainties exist in lunar base design that can be addressed only on the basis of a structural reliability analysis in order to assess safety in a quantitative manner.
As a result, an optimized structure can be designed from a holistic point of view, which is beyond that comparable to other designs also in terms of safety.
