Concordant outranking with multiple criteria of ordinal significance
- 62 Downloads
In this paper we address the problem of aggregating outranking statements from multiple preference criteria of ordinal significance. The concept of ordinal concordance of a global outranking situation is defined and an operational test for its presence is developed. Finally, we propose a new kind of robustness analysis for global outranking statements integrating classical dominance, ordinal and classical majority concordance in a same ordinal valued logical framework.
