CODE 98218 ACADEMIC YEAR 2023/2024 CREDITS 4 cfu anno 1 ENGINEERING TECHNOLOGY FOR STRATEGY (AND SECURITY) 10728 (LM/DS) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/09 LANGUAGE English TEACHING LOCATION GENOVA SEMESTER 1° Semester TEACHING MATERIALS AULAWEB OVERVIEW The course provides the fundamentals to robust design of systems and related procedures for moitoring and diagnostics, encompassing deterministic and stocastic approaches. Practical examples are derived from the mechanical engineering and energy system fields. AIMS AND CONTENT LEARNING OUTCOMES The course aims to illustrate how the design under uncertainty can help in modelling and design of the energy systems. The first part of the course will cover the necessary fundamentals of statistics. Then different uncertainty quantification methods will be presented, starting from sampling method like Monte Carlo and continuing with different approximated methods an overview of robust design will presented, focusing on the application of uncertainty quantification method in optimization problems. In the second part of the course, advanced techniques for Data Driven monitoring will be presented. Both methods will be applied to different case studies. AIMS AND LEARNING OUTCOMES At the end of the course the student will be able to: - approach and quantify the uncertainties impacting on a specific design problem - use mathematical methods for estimating the uncertainty in the design outputs - conduct a systematic design of experiment and treat design problems under uncertainty - apply robust design techniques to engineering problems - recognize the most common monitoring and diagnostic strategies - design a monitoring system selecting the most relevant parameters - select the most promising modelling approach on the basis of the available system information PREREQUISITES basic analytical skills, equation handling, basic computer coding skills TEACHING METHODS Lectures and exercises on PC SYLLABUS/CONTENT Part A – Robust Design of Systems Lecture 1 – Introduction and motivation Course introduction, practical needs and applications of uncertainty quantification and robust design techniques.
