Teaching method

Lectures: presentation of concepts, techniques and methodologies of analysis, discussion of case studies.
Practical classes: performing automation projects involving the components of the specification, solution development and implementation.

Evaluation method

During the semester are developed 3 projects (P1, P2 and P3) . The assessment for each project focuses on a report, individual assessement and student contribution for the project.

The final grade is obtained by the expression:

Final grade = 0.3 * P1 + 0.3 * P2 + 0.4 * P3.


Attention: Required minimum attendance of 67% in practical classes. Minimum of 9.5 values ​​in each of the evaluation components.
