I am programming belowed model.

In this model how can i make the variable bounds.

since it is bounded by variables, i coudnt simply write W(i)U as a ub in W(i)M.

  Hi Birkan,

  You can add these separately as standard constraints. As opposed to including them in the variable definition you are trying.

  for i in I:
      model.addConstr(w_u[i] >= w_m[i])
      model.addConstr(w_m[i] >= w_l[i])

  For the strictly greater than 0 bound you can adapt the idea described at: Why doesn't Gurobi support strict inequality constraints like x < a?

  Cheers, 
  David
