A manufacturing control system used in the manufacture of semiconductor products. The system has a custom business logic controller which can be used to define and implement custom business logic that departs from the conventional business logic associated with the several elements of the manufacturing control system both rapidly and in real time. The custom business logic controller is implemented by defining desired business logic within the definitional environment of the controller. Where custom business logic is required, the manufacturing control system operates to activate the custom business logic controller, which then proceeds to execute the desired (custom) series of business logic units. Within this series, the custom business logic controller can execute a continuous series of business logic units, or certain business logic units can be executed conditionally, based on the success or failure of a prior business logic unit or units, or based on some other environmental condition. As a result, any new logic can be easily implemented, without requiring any direct changes to be made to the existing (current) systems, and in such a way that there is no negative impact on production.
