On a Function Representation in an Imperative Program Model Specified by Petri Nets

Abstract

In the article an approach to constructing in terms of Petri nets a function model as a program model unit is considered. This approach makes it possible to present a program control flow model in a whole as a composition of constituent control flow models of each function. In the article constructions of function call and function body are introduced on the base of Petri net object, and then an operation of directed composition of Petri net object is defined that represents a control flow transfer between caller and called functions.
