Abstract: The dynamic behavior of the basic modeling elements of the real-time structured-analysis specification method has been defined with an object-oriented approach as a hierarchy of classes of Smalltalk-inscribed Petri nets. As a result of this definition, a given instance of a structured-analysis basic modeling element can be derived as an instance of the corresponding net class.
