Teaching Methods The professor's didactics, will be supplemented by seminars and conferences, at optional frequency, held by companies and publica institutions experts, invited to repport experience and expertise related to the topics of the course.
Evaluation methods Verification of learning:
Learning assessment methods:
Type of exam: Oral
The verification of the learning will be carried out with an oral test on the topics covered; in particular, an in-depth study on the quality, typicality and sustainability of supply chains aimed to verify knowledge, understanding, autonomy of judgment, communication skills, and the ability to develop links between the different contents of the course.
The oral exam will be evaluated with a score expressed in thirtieths.
