This very simple data set describes six cars with their real evaluations (according to the manufacturer’s web site), hence the name. Thanks to Quantin Hayez for having gathered the data.
It also includes a few preferential informations meant to be used with electre or promethee (namely, thresholds and weights).
In addition to the XMCDA formatted files, it also contains a spreadsheet file (.ods) that shows the same data, and the results of a few basic computations such as the electre concordance, outranking relations, promethee flows, ...
The complete case is here.
Update June 2010: this complete case now contains more data (promethee profiles, electre tri assignments, etc.).
