I forget to mention one thing, for each nurse (i), it has only either day(D) or night(N) or Both(B)

So, very nurse has only one of these three (Di,Ni,Bi)

This forum is not appropriate for requesting AMPL formulations of problems copied from printed materials. If you attempt to write your problem in AMPL and you get stuck on a specific question (like, "Why is there a syntax error on line 3?") then this forum may be able to help you with your question. However, if the problem was assigned in a course that you are taking, then you should consider asking for help from your school's staff or from other students, since we cannot guarantee a fast response to questions posted here.
