Computers solve the legible problems. But scheduling is one where the problems lack in hard specification, and plans involve several "layers" of prioritization, so what's called for is approximate results that avoid failure modes, which is something a skilled human does pretty well. I do think that software speeds up some parts of the process, but like so many automated processes, it's computer assistance, not computer intelligence.
