During the time of the first Apollo missions, a dominant portion of computing research was funded by the defense department and related arms of government, making this type of deterministic and WCET (worst case execution time) a dominant computing paradigm. Now that we have a huge free market for things like online shopping and social media, this is a bit of a neglected field and suffers from poor investment and mindshare, but I think it's still a fascinating field with some really interesting algorithms -- check out the work of Frank Mueller or Johann Blieberger.
