Continuous-dynamic modeling of LPG circulation: A preliminary study in a simple system of one filling station-one agent-one store

Certain important commodities circulate in the community in certain packaging containers where
the empty containers must be returned to the upstream. The existence of these containers is actually
beneficial in evaluating the adequacy of the availability of these commodities in the community.
The analysis generally uses mathematical methods or discrete simulations. In this paper,
continuous modeling is used to study the cyclical movement of LPG tanks from the filling station,
to the agent, to the store, to the consumer, back to the store, back to the agent, and back to the
filling station. The modeling uses a system dynamics language which even though it assumes the
entity is a fluid (continuous material) can be used for the discussion of discrete systems. In fact,
the modeling turns out to be simpler to do and has the potential to be extended to more complex
systems.
