A multicriteria decision making framework in ordinal context based on Sugeno integral

The paper presents a construction of a multicriteria decision model in a purely ordinal context, based on the use of Sugeno integral. The construction is built on the preference relation of the decision maker over a set of prototypical acts. The construction can cope also with negative scores, due to the introduction of a symmetric ordinal scale with suitable operators, which leads to the concept of symmetric Sugeno integral.
