The course aims to introduce the main methods and quantitative models to support the management and businesses in international markets, within certain and uncertain, with particular attention to operational applications.
The course is divided into parts in each of which it is introduced a quantitative model and are then proposed applications to specific business contexts.
At the end of the course, the student will have acquired various skills on the main quantitative tools to support business management and will be able to apply the main quantitative models developed for this purpose.

Didactic methods: for the course, the course consists of 54 hours of frontal lessons, developed with applications and simulations, in English (and Italian), with numerous case studies and tutorials. There are also hours dedicated to the preparation of Project Work. Throughout the academic year, there is also an individual reception service handled by the teacher at the times indicated on the web pages (no need to set a specific appointment) and constantly updated. The contents of the textbooks, as well as lessons and exercises held in the classroom, are part of the program. The program and study materials are the same, regardless of the frequency to the lessons.
To access the exam, the student must first develop a project work that will have to get a positive evaluation of the teacher.
The project work will be developed, with the help and under the supervision of the teacher, in study groups of up to 4 students that will have to make application and/or insights of the techniques, models and methods developed and produce a written, The Project Work, to be sent to the teacher via e-mail, for evaluation.
The project work is part of the methods of active participation of students in the course and is introduced with the aim of:
- Stimulate the student to the coordination and use of various instruments designed for operational purposes;
- Improve the capacity and quality of interpersonal relationships and in particular the work in teams;
- Improve the capacity and quality of presentation/display using patterns and vocabulary typical of the asset management.
To be admitted to the written test, students will have to obtain a favorable opinion on Project Work.
The exam consists of a written test on all the topics in the program, designed to test the knowledge gained.
The commission may request an oral evaluation aimed to further verify the mastery of knowledge acquired in connection with the use of operational cases.
