A problem facing the product development community is developing simultaneous solutions of response variables (to several properties) that depends on a number independent or sets responses. Harrington, among others, addressed this and presented desirability function with functional approach. Derringer Suich altered their approach illustrated how multiple can be transformed into convenience func...
