1.2 The Modeling Process


What is modeling

What is Modeling?

Modeling is the application of methods to analyze complex, real-world problems in order to make predictions about what might happen with various actions.


Stochastic behavior

*Στόχος

= “aim” or “guess”

Stochastic* Behavior

A system exhibits probabilistic or stochastic behavior if an element of chance exists. A probabilistic or stochastic model exhibits random effects, whereas a deterministic model does not.


Static vs dynamic models

Πάντα ῥεῖ

Static vs. Dynamic Models

A static model does not consider time, whereas a dynamic model changes with time.

Heraclitus (ca. 535–475 BC)


Continuous vs discrete

Continuous vs. Discrete

In a continuous model, time changes continuously, while in a discrete model, time changes in incremental steps.

Zeno of Elea (ca. 490 BC? – ca. 430 BC?)


Verification vs validation

Verification vs. Validation

The process of verification determines if the solution works correctly, while the process of validation establishes if the system satisfies the problem’s requirements.
