At the end of the semester, students should be able to:
- evaluate work cycles, in a perspective of operations efficiency and productivity;
- define operations normal time, standard time and work allowances;
- evaluate micromotions and value-added activities;
- structure a line production flow and cell production flow;
- define a process mapping in order to optimize industrial or service processes.

Not applied. There are no specific units established as "precedents".
Theoretical lectures are used to explain fundamental concepts and common techniques.
Practical sessions are used for problem-solving and practice, concerning knowledge presented during the lectures. Most practical work is based on screening of videos, recorded in real work situations, and by observing simulated activities developed during Lab sessions. The subjects covered in the lab(practical) sessions are:
TP1 - Time Study; time measurement techniques with chronometers.
TP2 - Application of MTM-1 technique (performing simulated operations in Lab)
TP3 - Operator''s multi-occupation (multitasking situations).
(1) Lectures (60% of the final grade; the minimum grade is 9,5 in 20): one final test or final exam.
(2) Laboratory (40% of the final grade; the minimum grade is 9,5 in 20): 10%TP1 (group); 5%TP2 (individual); 20%TP3 (group); 5%mini-assignment(s) to evaluation (individual).
(3) The laboratory grade is valid for one year.
(4) Final Grade = 0,6*Lectures + 0,1*TP1 + 0,05*TP2 + 0,2*TP3 + 0,05*Assignment(s)
