Controllers and methods of operating the same are introduced for use with a process facility that includes a plurality of associated processes. An exemplary controller includes circuitry that maintains a range of possible values of at least one measurable characteristic associated with at least one process of the plurality of associated processe s, and a processor. The processor is capable of selecting at least one value of said range of possible values from the circuitry in response to one of an input or an output of the at least one process, and generating control data as a function of the selected at least one value of the range of possible values and the input or the output of the at least one process. The controller is capable of using the control data to manage the at least one process.
