3 Petri-Net Data types

1. Workflow Model

Definition: The Workflow model represents the structured sequence of processes or activities aimed at accomplishing a specific task or goal. It defines the flow of tasks, decisions, and information in organizational processes or systems.

Core Components:

Usage Context: Used in business process management, software development, and automation systems to streamline and optimize processes.

2. Petri-Net Model

Definition: A Petri-net is a mathematical modeling language used for the description and analysis of systems characterized by concurrency, parallelism, synchronization, and nondeterminism. It extends beyond simple workflow models by providing a graphical and mathematical representation of distributed systems.

Core Components:

Usage Context: Widely used in the fields of computer science and systems engineering for modeling complex systems, analyzing performance, and verifying system properties.

3. Elementary Nets (EN) Model

Definition: Elementary Nets (EN) are a simplified version of Petri-nets focused on the fundamental aspects of system behavior, particularly the notions of causality and conflict without considering complex data or hierarchical structures.

Core Components:

Usage Context: ENs are used for modeling and analyzing simple systems or processes where the focus is on the presence or absence of conditions and the basic causality relationships between events. They serve as a foundational concept for understanding more complex Petri-net variants and are useful in educational settings or initial system design phases.

Each of these models serves different but complementary roles in analyzing and designing systems, from simple workflows to complex systems characterized by concurrent and parallel processes.
