Objectives

To learn how to evaluate work cycles, in a perspective of operations eficiency and productivity. To learn how to define operations normal time, standard time and work allowances. To know how to evaluate micromotions, and value-added activities. To learn how to apply work sampling. To learn how to structure a line production flow and cell production flow. To learn how to define a process mapping in order to optimize industrial or service processes.

Prerequisites

Not applied.

Subject matter

 

1. Introduction to labor legislation

2. Discussion of different technologies installed in industrial units: process, bulk, batch and unitary.3. Time study, as a tool for the evaluation and optimization of industrials activities: the time study methodology. Operator activity factor. Activity allowances. Observed, normal and standard time.4. Man-machine cycles, as a methodology of work cycle evaluation, involving operator - equipment interaction.5. Operators pluriocupation, as a methodology of work cycle evaluation, involving the interaction between an operator and several equipments.

6. Predetermined Time Systems, as a methodology of microscopic evaluation of upper limb movements: MTM-1 system

7. Line production flow, regarding the competitive advantage in relation to other forms of production flow; cycle time, frequency, idle time and operations synchronization; line dimensioning techniques and performance evaluation.

8. Cell production flow: competitive advantage and strategic objectives related to its implementation; automatic, semi- automatic and intensive manual work cells; dimensioning techniques.

9. Human Factors in industrial production: task dimensioning and the implications in workers psychological state; workstation redimensioning techniques; individual workstations and work groups; different functional structures at operational level and its connection to vertical and horizontal differentiation, and to communication effectiveness.

10. Process mapping of industrial or service processes

Teaching method

Practical classes are used for problem resolution, concerning knowledge presented in the theoretical classes. Most practical work is based on viewing of videos, taped on real work situations and by observing simulated activities developed during lab classesw. The subjects treated is the classes are:

1 – Time Study.

2 - Work sampling

3 - MTM-1 application

4 – Operators pluriocupation.

5 - Time estimating

6 - Process analysis diagram

7 - Process mapping

8 - Operator-machine cycles analysis

7 – Production cells Simulation

Evaluation method

(1) The students have to attend two quizzes (2) The average ratings of the two quizzes should be greater than 9.5; (3) If the average of he quizzes is less than 9.5, the student must carry out a final examination; (4) it is carried out lab work for evaluation; (5) In addition to the delivery and approval of the lab work, the approval of the course requires the delivery of at least 80% of the individual work sheets; (6) the approval of the discipline frequency is valid for consecutive years; (7) the lab work is done in groups of 3-4 students; (8) Classification lower than 9.5 values in the TP or delivery of less than 80% of the individual assessment sheets, does not confer frequency to the discipline, and the student must enroll in the next academic year; (9) for the calculation of the final grade in the course, the average grade of the quizzes has a weighting of 70% and 30% for the lab work, (10) In the case the student performs the final examination, the minimum classification for approval is 9.5 values. In this case, for the calculation of the final classification, the classification will have a weight of 70% and the lab work of 30% (11) The class attendance is required with delivery of individual work sheets at the end of lab classes; (12) in addition to the delivery and approval of the lab work, the approval of the course requires the delivery of at least 80% of the individual work sheets.
