The course aims to provide the main concepts, models and tools of Operational Research that allow to solve a wide spectrum of complex decision problems.
Knowledge and understanding
The student must demonstrate knowledge and understanding of:
a) the main aspects of optimization problems;
b) the methodologies and software tools for solving optimization problems
Applying knowledge and understanding
The student must demonstrate to be able:
a) to know a set of methods and understand their use in different contexts;
b) to formulate problems analytically;
c) to select the most suitable methods for solving the problems;
d) to use software tools to solve decision problems.
The student must be able:
a) to know how to evaluate the resolution methodologies in relation to the considered problem;
b) to implement the most suitable algorithms needed for solving the problems
The student must have the ability to explain in a simple way the main methods of linear programming and the network models .
The student must be able to:
a) elaborate, organize, summarize the acquired course contents;

The objective of the exam is to check the level of achievement of the objectives previously indicated.
The exam is divided into two parts:
a) a numerical test with the aim of assessing whether the student is able to apply the methodologies studied during the course. The numerical test requires to solve linear optimization problems, non linear optimization problems and network models The test must be completed in 90 minutes, and students pass the test if at least two problems are correctly solved. b) An oral test to verify the level of knowledge of the topics covered during the course. The oral test typically consists in two questions, one dealing with linear optimization methods and one dealing with the remaining arguments of course. The oral test is usually completed in 30 minutes. The final grade is the average value of the two grades achieved by the student in the numerical and oral tests.
The professor is fluent in English and he is available to interact with students in English, also during the examination.
