Example: Description and Evaluation of Cars

Options evaluated by the Car Evaluation models are, obviously, cars. This example illustrates two basic concepts: description of options and evaluation of options.

Interpretation

The table at the bottom shows two options, Car1 and Car2, described by the qualitative values assigned to the six basic attributes of the tree.

These values then aggregated from bottom to the top of the tree of attributes according to the structure of the tree and defined utility functions. In this way, intermediate evaluation results are first obtained and assigned to the attributes PRICE, COMFORT and TECH.CHAR. (see the table at the top). Finally, the values of PRICE and TECH.CHAR. are aggregated into CAR, giving the overall evaluation of both cars.
