##### Module Details

The course aims at educating undergraduate students in the scientific field of Operational Research and Management Science (Decision Making) with applications in Engineering.

The objective is to familiarize students with the basic knowledge, methods, techniques and skills required to analyze, model and optimize systems and solve related problems that often involve the allocation of limited resources and competitive activities.

The course focuses on Mathematical Programming, in particular on Linear Programming and the basic principles of Integer and Mixed Integral Linear Programming. In detail:

- the graphical method and the Simplex method for solving Linear Programming problems with continuous variables
- sensitivity analysis and duality theory
- integration of integer variables in mathematical models

Course’s important goal is the use of modern software tools for a modern and integrated application of theory in Engineering discipline.

After completing the course, students will be able to:

- Understand the importance of Decision Making, its process, conditions and stakeholders.
- Identify and associate real problems with standard Operational Research problems.
- Build standard Mathematical Programming models.
- Select the most appropriate method for solving optimization problems.
- Understand and interpret the solution results and identify the most important parameters of the problem.
- Assess the impact of resulting solutions under a comprehensive and multidimensional perspective.
- Use information technology tools to build and solve optimization problems as also performing solution analysis.
