The production manager of a large Cincinnati manufacturing firm once made the statement, "I would like to use Linear Programming (LP), but it's a technique that operates under conditions of certainty. My plant doesn't have that certainty; it's a world of uncertainty. So LP can't be used here." Do you think this statement has any merit? Why or why not? Explain why the manager may have said it and then further substantiate his argument or compose a rebuttal.
