2.7 Event-B Concepts


Goals: This section is an overview of the fundamental concepts of Event-B.

In Event-B we have two kind of components. A context describes the static elements of a model. A machine describes the dynamic behavior of a model. We have already used a machine to model the traffic light problem in Section 2.4. In the last section (2.6), we used a context to model the Agatha problem.
