PythonPDEVS Introduction

PythonPDEVS is a Python implementation of the Parallel Discrete Event System Specification (PDEVS) formalism. It provides tools to model and simulate systems as a combination of atomic and coupled models, enabling hierarchical and modular system design.

Atomic Models:

• The basic building blocks of a DEVS system.
• Define state variables, internal and external transitions, output functions, and time advance functions.
• Handle input and output events independently.
• Each atomic model simulates the behavior of a single component.

Coupled Models:

• Allow combining multiple atomic models (or other coupled models) into a larger system.
• Define the connections (couplings) between submodels.
• Provide hierarchical composition, enabling complex systems to be built from simpler components.
• Do not define behavior themselves, but manage the structure and communication of submodels.

In PythonPDEVS, you build a system by first creating atomic models (with logic and state changes), then integrating them into a coupled model to define how they interact and exchange events.
