If you convert the Min Z to Max Z' then normal process will be used that is, adding (-Ma1....-Man) to the objective function. If you don't convert Min Z to Max Z then you will need to add (Ma1....+Man) to the objective solution. But in this case, in the table if (Zj - Cj) 0 then the column with most positive ∆j value will become the Incoming Vector i.e., Xk.
