1. A system for dynamically adjusting linear program objective function coefficients of variables associated with the performance of a process, the system comprising: a database configured to store a plurality of manipulated variables each in respective association with at least one controlled variable dependent on the plurality of manipulated variables; a multivariable constraint controller including a linear program optimizer configured to perform a linear program optimization for each association of the manipulated variables and the at least one controlled variable stored in the database; an input unit configured to receive a set of inputted objective function coefficients that cause the linear program optimizer to target a specified set of constraints, and to receive a set of inputted instructions causing the linear program optimizer to perform a linear program optimization for a plurality of combinations of the manipulated variables and the at least one controlled variable being switched on and off; and an output unit configured to output the linear program optimization performed by the linear program optimizer for a plurality of the on/off combinations of the manipulated variables and the at least one controlled variable, and to output a notification of whether any on/off combination causes the linear program optimizer to deviate from the specified constraints, wherein, when the output unit outputs the notification, the input unit is configured to receive modified objective function coefficients causing the linear program optimizer to target the specified set of constraints.
