PROBLEM TO BE SOLVED: To allow an optimization technique used for driving a process plant controller, such as a model prediction controller, to create a solution that is used by the controller and achievable by using a method that is organized and systematized, and simple in terms of a computer for relaxing or redefining the constraint in operation variables/constant variables/auxiliary variables, when no feasible, optimum solution exists within a preset constraint. SOLUTION: An optimization routine uses a slack variable given penalty, or redefines a constraint model along with the use of the penalty variable for creating a new object function, and determines a control solution for fully satisfying the initial constraint limit by using the new object function.
