Knowledge of the ergonomic principles relative to work organization and to the verification and design of workplaces and work tools. Knowledge of the main methods of risk assessment in work activities and for the integration of ergonomics in setting working times and in line balancing To develop skills in the applications of the ergonomic principles to work organization, workplace design, choice of work tools as well as in the definition of work and production methods.

The course is organized in 36 hours of lessons, 12 hours of class tutorials and 12 hours of computer lab modules. Class tutorials consist in the analysis of case studies and exercises for risk assessment method application. Problems are solved in class with the active participation of students. Computer lab modules are dedicated to the ergonomic software Siemens Jack: 9 hours are dedicated to guided tutorials + 3 hours are dedicated to a final assignment students have to work on. Students are requested to upload the simulation file at the end of the assignment and to prepare a power-point presentation they will discuss during the oral exam.

Documentation in help is prepared and distributed by the lecturer. Suggested books: MS Sanders, EJ McCormick “Human Factors In Engineering and Design”- Mc Graw Hill. D Meister, TP Enderwick “Human factors in system design, development and testing” – Taylor & Francis

Exam: Written test; Compulsory oral exam;

The exam is aimed at ascertaining knowledge of the topics listed in the official course program and the ability to apply the theory and related calculation methods to solving exercises The exam consists in a written test and an oral colloquium. The final mark will be the average of written and oral. In the written test (open books), students will be asked to solve 3-4 exercises on the topics illustrated in the course program and similar to the exercises assigned during class tutorials. The exercises comprise numerical calculations on risk assessment method computation and work organization protocols , as well as open questions which have the purpose of verifying the level of knowledge and understanding of the topics covered during the course. The duration of the written test is 3 hours and the maximum score is 30/30. 18/30 is the minimum score to access the oral exam. Examples of exercises from past exams are provided as part of the class tutorials. In addition, one or two full texts from past exams are published on the portal in the last month of the course for students to practice. The oral exam will cover the material taught in the course. Students are expected to prove an overall understanding of the basic ergonomic principles as applied to the design and verification of workplaces as well as of the identification and application of risk assessment methods to different work contests. During the oral colloquium, students will also be asked to present and discuss the final assignment of the computer lab modules, illustrating the reasons for their choices in the evaluation and re-design in virtual of the workplace. The correctness of the work and the level of understanding demonstrated during its discussion are part of the evaluation of the oral exam.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
