With shortened product lifetime and diversified kinds of the products, it has become necessary to quickly develop and change control software for automation of the manufacturing process. So a system which can automatically introduce the control operation only by declaring the control specifications as the rule has been sought. For this to be used as a kind of language for development of the control software system needs: (1) a process interface system able to flexibly; respond to construction and modification of the sensor actuator for each object; (2) a high-speed processing system applicable in real time; and (3) a method for the estimation of the design processing time. The authors described a rule-based control software system, SCD (Station Coordinator), for automation of the manufacturing process to meet with the above requirements.
