## MODELS AND METHODS FOR DECISION SUPPORT

CODE 94628 2020/2021 5 credits during the 1st year of 10553 ENGINEERING FOR NATURAL RISK MANAGEMENT (LM-26) SAVONA MAT/09 English SAVONA (ENGINEERING FOR NATURAL RISK MANAGEMENT) 2° Semester This unit is a module of: AULAWEB

## OVERVIEW

The course presents a set of mathematical models and methods for solving decision problems with a particular reference to natural risk and emergency management. The purpose of this course is to provide the students with competences in using a set of models for problem solving. In particular, the course mainly considers optimization problems faced by mathematical programming techniques and problems on graph and networks.

## AIMS AND CONTENT

### LEARNING OUTCOMES

The course allows acquire knowledge on a set of Operations Research (OR) models and methods (mathematical programming models; integer programming methods; graphs and network models) and problem solving capability by a set of OR techniques (formulation of mathematical programming models and use of mathematical programming algorithms; algorithms for problem solving on graph and networks).

### AIMS AND LEARNING OUTCOMES

As regards mathematical programming, the main objective is to provide the students with skills for defining the right model to solve a set of decision problems formulating them as optimization problems. In particular, continuous and mixed integer programming algorithms are presented and applied to different cases. Such methods, together with methods for graph and network, represent fundamental optimization tools for their possible applications in natural risk and emergency management.

### TEACHING METHODS

The course consists of classroom lectures.

The exam consists in a written and/or oral test
