The module aims at providing the basic knowledge on the ergonomics for manufacturing systems, emphasizing how the “human centered” design of manufacturing processes and operation management may reduce the physical and mental workload sustained by the operator, improve his well-being and the system productivity (in the respect of gender issues and of people with special needs).

Knowledge on the main methods of risk assessment, ergonomic design and evaluation of the workplace, digital human modeling, human-machine interaction

Equilibrium equations and free-body diagram determination. Rigid bodies kinematics. Main statistical distributions.

Basic Knowledge o Static and functional anthropometric data. Databases and scaling techniques o Use of percentiles in design. Types of design o Elements of physical capabilities (mobility of joints, muscular strength and endurance). Data sources Digital Human Modeling o Human manikins (classical percentile approach, human scale standard, multivariate manikins) o Testing of reach-ability, body space and postural comfort o Biomechanical modeling, loads at joints and strength percent capabilities Workplace Design o Work-related musculo-skeletal disorders. General classification and main risk factors o Manual material handling. NIOSH lifting equation. Snook & Ciriello Tables o Upper limb disorders. Hand intensive tasks. The OCRA method. Work tool design principles o Complex work content and whole body risk methods. EAWS main structure and examples o Legislation and standard overview for risk evaluation (ISO 11226; ISO 11228 series; EN 1005 series) Work Measurement o Principles and brief history of Time and Motion Studies. Main observational methods o Predetermined Motion Time System. Main structure and example of MTM-UAS o Integration of ergonomics in setting working times and in line balancing Human-Machine Interaction o Principles of human-machine interaction o Ergonomics in Industry 4.0 o Human-oriented evaluation of cobots and exoskeletons

Class tutorials consist in the analysis of case studies and exercises for risk assessment method application. Computer lab modules are dedicated to the ergonomic software Siemens Jack

Modalità di esame: Prova scritta (in aula); Prova orale obbligatoria; Progetto di gruppo;

Exam: Written test; Compulsory oral exam; Group project;

... 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 (didactic material at hand), students will be asked to solve 3-4 exercises, similar to those assigned during class tutorials, and to answer to open questions. 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. The oral exam will cover the material taught in the course. Students are expected to prove an overall understanding of the basic ergonomic principles. During the oral colloquium, students will also be asked to present and discuss the work done during 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.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
