Assessment of space station on-orbit maintenance task complexity

The safe operation of a space station relies on a large amount of on-orbit maintenance. On-orbit maintenance task complexity (OOMTC) plays an important role in maintenance processes, maintenance program assessments, astronaut training and scheduling, and space station maintainability design. However, only a few studies involve on-orbit maintenance complexity assessments. We proposed an OOMTC assessments model based on graph entropy. The model...
