The current economic models which have been implemented over decades within the globalized world do not reflect enough the need for balancing the objective factum of limited resources and the key requirements of sustainable economy as represented by an optimal solution and fair distribution. In addition they tend to deal primarily with linear processes in permanently changing societies.
The conditions in a society can never be the same and repeated as those in a laboratory. Practice as well as theory often includes situations where multiple ways to achieve a goal exists.
These ways constitute what we recognize as admissible solutions whereas the best way, which may constitute a single way or multiple ways, is referred to as the optimal solution. The article proves that if there is an optimal solution to a problem, then each of its sub-optimal solutions incurs a loss, irrespective of whether a single optimal solution or several optimal solutions to the problem exist.
