Shift scheduling/rostering is obviously very widely researched, with tons of papers around it. I found the review papers by Van den Bergh et al.  and Ernst et al. , but am looking for something that actually shows the various types of math models that have been used for this with the relevant extensions.
Could you please point me to the relevant books/book chapters/papers for this? Thanks!
