This paper describes an original approach to discrete event control of continuous processes by means of expert knowledge. We present an application of this approach on the SACHEM diagnosis subsystem. The SACHEM system is a large-scale knowledge-based system that aims in helping a set of operators to control the dynamics of complex continuous systems (e.g., blast furnaces). The proposed method is based on: (i) The definition of a language facilitating the acquisition and representation of expert knowledge, called ELP (Expert Language Process); (ii) The use of the DEVS formalism to make ELP models operational; (iii) Algorithms for exploiting operational models.
