## Description

## Ontology Info

| Field | Value |
|-------|-------|
| Acronyme | DEMO |
| Description | DeMO is an ontology for Discrete-event Modeling (DeM) (system dynamics for Discrete-event Systems (DeS)). The models in the ontology focus on how the state evolves over time. The state is typically discrete (finite or countable), while time may be continuous (uncountable), although the number of state changes (events) must be discrete. We also focus on stochastic models, although deterministic models are considered as special cases.  |
