    Hello, I would like to know which formula did you wright in I5 please? I've doubled the values and it doesn't work. I suppose the problem comes from here. Thanks for your answer

      Do you mean I6? If so, that formula is =SUMPRODUCT(B4:G4,B6:G6).

    Hi, I'm working on some linear programming exercises and came across a question: how does the model forces Xi>0 whenever Yi=1? (when Yi=1, Xi may be equal 0 and the inequality would hold true)

      It doesn't! Xi can be zero- it's a feasible solution, but surely wouldn't be optimal. The constraint forces the reverse: Xi can't be greater than zero unless Yi is too (and being binary, that means =1).
