WebbUnder the Simplex Method, an unbounded solution is indicated when there are no positive values of Replacement Ratio i.e. Replacement ratio values are either infinite or negative. … WebbThese solutions are feasible as long as \(t \ge 0\) and we have \(\lim_{t \to \infty} z = \infty\). Whenever a linear problem is unbounded the Simplex Method will eventually tell …

WebbAs a simple example, you could add a new "slack" variable on each capacity constraint, having a very high penalty cost. Then infeasibilities in your capacities would be signalled by positive values for these slacks at the optimal solution, rather than by a mysterious lack of feasibility in the linear program as a whole. http://www.math.chalmers.se/Math/Grundutb/CTH/mve165/1112/Lectures/fo3-publish.pdf
