Abstract: The painting equipment controller controls automotive painting equipment so that desired painting attributes can be achieved. A database is used for storing mathematical models which interrelate painting factors with painting responses. The painting factors include the control settings of the painting equipment. The painting responses include such painting attributes as the appearance of the paint and application attributes of the paint. A database engine determines the values for the painting responses based upon the model and upon initially selected painting factor values. A cooptimizer uses the output of database engine to determine a second set of values for the painting factors which achieve the desired painting attributes. Thereupon, the painting equipment is controlled based upon the painting factor values as determined by the cooptimizer.
