Optimization: Finding an option with the most cost efficient or highest attainable performance beneath the given constraints, by maximizing preferred factors and diminishing undesired ones. In comparison, maximization means trying to achieve the highest or maximum outcome or outcome without regard to cost or expenditure. The practice of optimization is limited by the lack of full information, and the lack of time to estimate what information is accessible. In computer simulation (that is, modeling) of business troubles, optimization is attained generally by using linear programming methods of operations research.
