The student will be introduced to the research area of Multicriteria Decision Aid (MCDA).
The course covers three main issues:
(1) Preference structures for representing the interests of the decision maker. Special attention will be paid to the use of non-numerical information, such as linguistic variables, fuzzy sets or ontologies.
(2) Exploitation techniques of the user information to solve the decision problem. The two main approaches to MCDA will be studied: Multiattribute Utility Theory and Outranking Relations. At the end of the course, the student will have to know the theory, properties, advantages and drawbacks of those methods.
(3) Use of MCDA techniques in combination with other fields (f.i. Geographical Information Systems, Recommender Systems).
Free software will be used to practise.

    1. 1 Introduction
      "Multicriteria Decision Aiding" is a research field that is growing in importance recently.
      The use of AI techniques in this field is quite new and opens many interesting research lines.
      The first topic introduces the basic concepts and notation.

      1.1 The decision making problem. Formalization.
      1.2 MCDA applications
    2. 2 Preference representation models for user profiles
      To build personalised decision support systems we need to know and store the preferences of the users in an appropriate model. In this chapter, we study different representation models that take into account several data formats.

      2.1 Data types
      2.2 Family of criteria
      2.3 User profile construction and update
    3. 3 Multi-Attribute Utility Theory
      The course addresses two main approaches. The first is based on merging the utility of different criteria into a single overall score. Many fusion methods for aggregation will be presented and compared.

      3.1 Introduction
      3.2 Steps: aggregation and exploitation.
      3.3 Aggregation operators. Properties.
    4. 4 Models based on outranking relations
      The second approximation is more qualitative than quantitative. It is based on building a decision model with preference relations among a set of options.

      4.1 Introduction
      4.2 Outranking relations
      4.3 ELECTRE
    5. 5 MCDA and AI
      Use of MCDA in combination with other intelligent techniques can be applied in many different fields. Each course we study different lines according to the interests of the students. For example, MCDA in intelligent recommender systems, or in geographic information systems, or in web searchers, or electronic commerce, among others.
