Multi-Attribute Model
=====================

*Multi-attribute models* (also called *multi-criteria models*) represent
a class of models used in :doc:`Decision Analysis <DEXiGlosDAnal>` 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:

-  :doc:`attributes <DEXiGlosAttr>` and
-  :doc:`utility functions <DEXiGlosFunct>`.

| Attributes are organized hierarchically into a :doc:`tree of
  attributes. <DEXiGlosTree>`
| Each attribute takes values from the corresponding
  :doc:`scale. <DEXiGlosScale>`

Multi-attribute models are used for option :doc:`evaluation <DEXiGlosOpt>` 
:doc:`evaluation <DEXiGlosEval>` and :doc:`analysis <DEXiGlosAnal>`.

Multi-attribute models used in :doc:`DEXi <DEXi>` are
:doc:`qualitative <DEXiGlosQMAMod>`.
