Multi-Attribute Model

Multi-attribute models (also called multi-criteria models) represent a class of models used in Decision Analysis that evaluate options according to several, possibly conflicting, goals or objectives. In principle, a multi-attribute model represents a decomposition of a decision problem into smaller and less complex sub-problems. A model consists of:

• attributes and

• utility functions.

Attributes are organized hierarchically into a tree of attributes.

Each attribute takes values from the corresponding scale.

Multi-attribute models are used for option evaluation evaluation and analysis.

Multi-attribute models used in DEXi are qualitative.
