Original Abstract

Application run tracing and step-by-step execution are an integral part of the debugging process. In many cases, debugging would be more comfortable and faster if it was possible to go back in the execution and examine the system state before getting into the wrong or disabled state. Currently, such a technique is not widespread, but there are experimental implementations that burden the application run with logging information needed to restore previous states.  Moreover, many of them increase overhead in a significant way. This paper focuses on the possibility of reversing the run of systems whose behavior is described by Petri nets. The work follows the methodology of designing and validating system requirements using functional models that combine formal notation with objects of the production environment and can be used as a full-fledged application. Due to the nature of Petri Nets formalisms, it is possible to define reverse operations to reduce the overhead of application run.
