Objectives

- Introduce basic Decision Theory definitions;

- Present several different models used in Decision Support Systems;

- Introduce students to problems related to the subjectivity of Decision Making and how different methodologies handle those problems;

- Facilitate the students'''''''''''''''' contact with quasi-real Decision Making Processes by exposing them to small Case Studies. These Case Studies are usually inspired by real situations.

- Generalize Linear Programming to Multi-Objective approaches;

- Present several methods for finding Efficient Solutions in MOLP problems.


Prerequisites

Although not fundamental, previous knowledge of  Linear Programming is recommended.

Teaching method

In each 4 hour lesson a new topic is presented and the students explore it by studying and solving a related Case Study.

The proposed solutions are discussed by the classe and corrected.

Lessons are held on a computational lab.

 


Evaluation method

A student has to attend to a minimun of 2/3 of held lessons. Otherwise, the student will be excluded from evaluation and will fail.

During the semester there will be two 90-minutes mid-term tests (graded 8 points each) and a group project (graded 4 points).

Being CTi the grade of Test i and CT the project grade, a student will succeed if  CT1 + CT2 +CT>= 10. 

A student who fails on the mid-terms tests can try to succeed on the Final Examination.

 Let CE be the grade on the Examination. A student will succeed if  CE >= 10.
