The aim of this work is to present a model to represent the supervisory control Structure organized by activities of an order driven multipurpose batch plant. In this control structure each activity of the plant has its own supervisory control and all of them are coordinated by a supervisory control structure at the level of orders. In this work we present a framework to represent the supervising control of an order driven multipurpose batch plant operated by activities. The framework is based on a strategy that uses Petri nets to describe and analyze the supervising control. This strategy permits to automate the modeling of the supervising control. Based on this framework we developed a supervising control support system (SCSS) of an order driven multipurpose batch plant operated by activities.
