We have not discussed reduced costs in this chapter because the information
they provide can also be gleaned from the allowable range to stay optimal for the
coefficients in the objective function , and these allowable ranges also are readily

For each b ; the allowable range to stay feasible gives this range if none of the
other b ; are changing at the same time . What do these allowable ranges
become when some of the b ; are changing simultaneously ? A partial answer to
