## MODELS AND METHODS FOR DECISION SUPPORT

CODE 94628 2022/2023 5 cfu during the 1st year of 10553 ENGINEERING FOR NATURAL RISK MANAGEMENT(LM-26) - SAVONA MAT/09 English SAVONA 2° Semester This unit is a module of: AULAWEB

## OVERVIEW

Decision making problems arising in a large number of application contexts can be modeled and solved by means of optimization methods and algorithm of Operations Research. This course aims at presents a set of mathematical models and methods from Operations Research  for solving decision problems with reference to natural risk and emergency management. Basic notion of optimization and mathematical modeling are provided. Specific attention is devoted to linear mathematical programming techniques and graph and networks.

## AIMS AND CONTENT

### LEARNING OUTCOMES

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 LEARNING OUTCOMES

The main objective is to provide students with the skills to define mathematical programming models to solve a series of decision problems by formulating them as optimization problems. Students will be able to solve continuous and mixed integer programming problems using appropriate methods and algorithms. Students will be able to solve problems using networks flow models and graphs. These models represent fundamental optimization tools for their possible applications in the management of natural risk and emergencies.

### TEACHING METHODS

The course consists of classroom lectures.

### SYLLABUS/CONTENT

## EXAMS

### EXAM DESCRIPTION

Written exam text and oral exam (optional after passing the written text). The students who want to take the exam must register online and send an email to the professor.

Students with learning disorders ("disturbi specifici di apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.

### ASSESSMENT METHODS

The students will be asked to solve linear and integer programming problems using the learnt algorithms and applying concepts from theory. They have to be able to sove problems on graphs and networks. They have to demostrate to know the basic concepts of multi-criteria decision making.
