Quantitative methods and decision aid

Quantitative methods seek in building up rational models for the representation of complex problems and in devising the related solution algorithms. Objective of the course is to deepen the student skills on several major topics of operations research with emphasis on computational complexity, combinatorial optimization and multi-criteria analysis.

Quantitative methods seek in building up rational models for the representation of complex problems and in devising the related solution algorithms. Objective of the course is to deepen the student skills on several major topics of operations research with emphasis on computational complexity, combinatorial optimization and multi-criteria analysis. The final aim is to provide students with theoretical and operational tools for modeling and solving real life decision making and optimization problems.

At the end of the course the student must be able to determine the computational complexity of given algorithms, to design exact and heuristic algorithms for real world combinatorial optimization problem, to know methods of multi-criteria analysis and use them in relation to specific decision problem situations.

The exercise classes are related to the topics presented in the course. The flow is such that 2 exercise classes are proposed every 5 teaching classes. Exercise classes are provided both in class and in laboratories. In the laboratories commercial software tools are used to deal with more complex problems.

Exam: Written test;

Quantitative methods and decision aid

The assessment is composed of two parts: the written test (60% of the final grade and the assignment (40% of the final grade). The assignment consists in the development and implementation by the students subdivided into groups of a heuristic procedure for a given combinatorial optimization problem. The assignment foresees also a description (by means of slides) of the proposed procedure including the relevant complexity analysis. The written test covers the multicriteria analysis part and is an open-book exam consisting of numerical exercises plus questions related to the analysis of applications of multicriteria methods. The typical exam duration is 1.5h.
