Models in Business Analytics
Model – an abstraction or representation of a real system, idea, or object.
- Captures the most important features
- A written or verbal description, a visual representation, a mathematical formula, or a spreadsheet.

Inputs:
- Data, which are assumed to be constant for purposes of the model.
- Uncontrollable variables, which are quantities that can change but cannot be directly controlled by the decision maker.
- Decision variables, which are controllable and can be selected at the discretion of the decision maker.
