Siirtymäkuviot

Siirtymäkuviot, known in English as transition diagrams or state transition diagrams, are graphical representations used to model the behavior of a system. They depict the possible states a system can be in and the transitions that can occur between these states. A state is a condition or situation a system can be in at a specific point in time. Transitions represent events or conditions that cause the system to move from one state to another.

These diagrams are widely used in various fields, including software engineering, computer science, and systems analysis, to design and understand complex systems. They help in visualizing the flow of control, identifying potential issues, and ensuring that all possible states and transitions are accounted for. The components of a siirtymäkuvio typically include states, often represented by rounded rectangles or circles, and transitions, shown as arrows connecting the states. Labels on the transitions usually describe the event or condition that triggers the change.

Siirtymäkuviot are particularly useful for describing the logic of finite state machines (FSMs). An FSM is a computational model that can be in exactly one of a finite number of states at any given time. The FSM can change from one state to another in response to some inputs; the change from one state to another is called a transition. By using siirtymäkuviot, developers can clearly outline the operational logic of a system, making it easier to implement, test, and maintain. They provide a clear and unambiguous way to communicate system behavior to different stakeholders.
