Abstract: Statechart has been utilized as a visual formalism for the modeling of complex systems. It illuminates the features on describing properties of causality, concurrency and synchronization. In this paper, we try to describe a behavioral logical operations language by using Statecharts. The logical operation is a date structure that is used to represent by a Boolean function. This paper used them to analyze the models which are modeled by using Statecharts. Their formalism provides a clear means for presenting control logic. Finally, an example of traffic light controller system is examined successfully.
