Space Station Freedom assembly sequence - History, methods, and status

Abstract

The goal of SSF assembly sequence design is to yield an operations-capable configuration at each stage of construction. Among the primary considerations of sequence designers are launcher payload-mass constraints, EVA time capabilities, and the ensuring of sufficient functionality at each construction stage. Trade studies are conducted to examine alternative hardware-delivery sequences; every iteration of this process either refines existing margins or reflects the redesign of one of the various elements.
