Learning outcomes

The course aims to give a systematic overview of the primary methodologies and technical norms that have to be used to rationally overcome issues related to faults and malfunctioning affecting modern engineering systems. The course topics include fault diagnosis methodologies as well as functional safety tools and standards that regulate the design of safety-critical systems. At the end of the course, - students will know fundamental tools and procedures to deal with failure/hazard analysis, occurrence/risk assessment, and occurrence/risk reduction; - students will know some relevant tools and methods to design fault detection and isolation algorithms linked to system and control theory.

REMARK: Contents are under review


Material provided by the teacher (teaching material) is available on Virtuale (virtuale.unibo.it)
(copies of the slides and handwritten notes, examples of exam questions, exam and registration rules, etc.).
Students are recommended to register in the Virtuale list as soon as possible in order to download the material and to receive communications about the course sent by the instructor to the list members. These communications are fundamental for the course and the instructor will assume that all of the Students are receiving them (no excuses will be accepted).
Password for registration will be given in the first lesson. For motivated late registrations, please send an email to the instructor with the following tag in the subject [D&C-M_LateReg].
Please, note that registering yourself in Virtuale does not imply that Diagnosis and Control M will be in your study plan. Virtuale is just a teaching support system. To include this course in your study plan (reported in Almaesami) as an elective course, you have to follow the procedure of your Master's degree program.

Remark: for some of the course topics, slides give just an overview and significant additional parts will be presented on the blackboard/virtual board. For such parts, some handwritten notes will be provided, but complete coverage of all contents is not guaranteed.
In general, Students are expected to take their own notes to cover completely all of the contents presented in this course or to ask classmates for notes, whether they cannot attend some lessons.

Teaching methods

Traditional classes, supported by PC presentations (copy of the slides are available on Virtuale).
Some parts of the course are presented only by using the blackboard (for such parts, students are recommended to take their own notes or to ask for notes to classmates, attending classes).

Lectures in collaboration with companies and academic institutions


IMPORTANT: For any communication to the instructor, students are requested to use email (no Virtuale messages - Virtuale will be used by the instructor only, to reach out to all of the students; no Teams messages; etc.). In addition, students are requested to put the tag [D&C-M] in the email subject, otherwise the email might be lost. Also, it is needed to put the course tutor in cc, as well as other people according to what requested by instructor during classes or what reported in the instruction file in Virtuale.

Assessment methods

Final written exam including theoretical questions and simple exercises.

Detailed rules concerning exam characteristics (including how to book it), marks and registration procedure are given in a pdf file in the Teaching Material on Virtuale.

IMPORTANT: in order to do the exam, it is MANDATORY to be registered in the exam session lists in Almaesami, by the closing date of the specific lists. No exceptions will be possible. Students are expected to pay much attention to their registration in the exam lists and the related deadlines.
Some messages might be sent to the list of Students registered for a particular exam session (in particular, after the closing of the list). These messages are fundamental for the exam arrangement (they include some mandatory instructions), therefore Students are recommended to read them carefully.
