Petri nets are specific types of modeling constructs useful in data analysis, simulations, business process modeling and other scenarios. This type of mathematical construct can help to plan workflows or present data on complicated systems.
Petri nets use elements like places, transitions and gates to describe complex procedures and model the workings of a system. Tokens and marking systems can show movement through these systems. Much of the model can be delivered in classic mathematical notation, or in specific drawings conforming to the syntax and makeup of the petri net model.
Petri nets have many practical applications in technology. One big example is where petri nets are used in business process analysis. Another example is where tools like sequential function charts (SFCs) in programmatic structures are useful for the observation and implementation of systems.
