The aim of optimization process is to find a good set of conditions that is sufficient to achieve the target. Derringer and Suich [40] described desirability, an attractive method for optimization of multiple quality characteristic problems. In order to meet the objectives of the problem, the right design should be chosen; a variable goal could be set to a minimum, maximum, within some range, or target value. To find combinations of the input variables, component proportions in a mixture setting, where one can come as close as possible to a goal, is the important reason for fitting models to data. This method transforms an estimated response into a dimensionless value called desirability and makes use of an objective function, called the desirability function. From zero (least desirable) to one (most desirable) is described as the range for such function. The value of desirability always=1 is not required as it is completely dependent on how closely the lower and upper limits are set relative to the actual optimum [41].
