INDUSTRIAL PLANTS

Academic Year 2025/2026 - Teacher: FERDINANDO CHIACCHIO

Expected Learning Outcomes

The course presents production systems from a management perspective and provides technical and economic tools for sizing and operating process and service plants. Expected outcomes include: (i) the efficient design of utilities and processes (SDGs 7, 9, and 12); (ii) the implementation of preventive/predictive maintenance geared towards safety and business continuity (SDGs 8 and 9); (iii) the development of digital solutions (monitoring, data-driven approaches, digital twins) for optimizing plant performance (SDGs 9 and 12); (iv) the technical and economic evaluation of investments (NPV, IRR) in energy transition technologies (SDGs 7, 9, and 13).
The teaching methodology includes lectures and exercises on application cases using spreadsheets; considerable emphasis is placed on the treatment of random variables and simulation approaches (e.g., Monte Carlo).
SDG = Sustainable Development Goals, i.e. the Sustainable Development Goals of the UN 2030 Agenda

Course Structure

Lectures on theoretical topics carried out by a video projector or overhead projector. Exercises carried out in the classroom using a video projector and the electronic spreadsheet. Collective development of numerical exercises. Short simulation of the exam (numerical exercise).

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Learning assessment may also be carried out on line, should the conditions require it.


Required Prerequisites

  • Knowledge of the: units of measuremens, basics of differential calculus, mechanical, thermodynamics and of electrical theory.
  • Prerequisite: Fisica Tecnica

Attendance of Lessons

To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and / or dispensatory measures, based on the didactic objectives and specific needs.

Learning Assessment

Learning Assessment Procedures

The exam consists of:

a.1) Optional partial written tests during the course; students are admitted to the oral exam (see point b) upon passing the written test with a score of 18/30. Students who score at least 15/30 in the written test are also admitted, though it is not recommended.

a.2) A final written test (if the student does not participate in the partial tests or does not achieve the minimum score); students are admitted to the oral exam (see point b) upon passing the written test with a score of 18/30. Students who score at least 15/30 in the written test are also admitted, though it is not recommended.

b) Oral exam: the exam includes an oral assessment of the topics covered in the course syllabus and the exercises completed by the students based on the materials provided.

Both parts a) and b) carry equal weight.

The assessment methods are thoroughly communicated during the lectures and published on STUDIUM.

NOTE: The assessment may also be conducted online if the circumstances require it.
