Objectives
- understand the complexity and quantitative and qualitative aspects of decision making processes, using simple approaches for their structuring;
- be able to create spreadsheet models and develop tools for decision support;
- use general concepts and principles of Decision Theory and Multicriteria Analysis, to structure decision alternatives and criteria;
- be able to perform data analysis and modelling, as well as sensitivity and scenario analysis;
- use optimization, heuristic and simulation models and algorithms, to suppor the solution of decision problems;
- understand the problems associated with the design of Decision Support Systems e be able to contribute to their specification.

Teaching methods and learning activities
Classes will be used to introduce the program topics, present and discuss cases, and solve small illustrative problems.
Some sessions may be occupied with student presentations and subsequent discussion.
The reports to be presented (as part of evaluation) will essentially be developed out of class.

Eligibility for exams
General rules of evaluation, article 4th.
Calculation formula of final grade
FE (final exam, closed book) - 0 to 20 points (minimum 8)
A1 (on program topics 1 and 2) - 0 to 20 points
A2 (on program topics 3 and 4) - 0 to 20 points
A3 (on program topics 5 and 6) - 0 to 20 points
Final grade (before rounding):
0.55 FE + 0.15 A1 + 0.15 A2 + 0.15 A3
Examinations or Special Assignments
The assignments evaluation may include brief discussions with the students.
Special assessment (TE, DA, ...)
Evaluation identical to normal case.
All students (including working students, ...) must deliver the assignments in the established date.
Classification improvement
Exam only.
The students may not repeat components A1, A2, and A3 of evaluation.
