In this pedagogical note we present an improved method to solve and analyze linear programming (LP) problems. The method depends on solving a system of equations and is free of any slack, surplus or artificial variables. The proposed method eliminates the need to manipulate linear inequalities...

The more-for-less (MFL) phenomenon in distribution problems occurs when it is possible to ship more total goods for less (or equal) total cost, while shipping the same quantity or more from each origin and to each destination. This paradox occurs often in fixed-charge transportation problems...
