SSD CFU Activities Area context
ING-IND/14 6 B - Caratterizzanti Ingegneria meccanica
Subject fundamentals
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).
Expected learning outcomes
Knowledge on the main methods of risk assessment, ergonomic design and evaluation of the workplace, human-machine interface.
Prerequisites / Assumed knowledge
Equilibrium equations and free-body diagram determination. Rigid bodies kinematics. Main statistical distributions.
Contents
BASIC KNOWLEDGE
Outline on main sensory capabilities (visual and auditory sense) and main cognitive capabilities involved in information processing (attention, perception, memory, decision making).
Elements of physical capabilities (anatomy of the spine, mobility of joints, muscular strength and endurance). Data sources. Biomechanical modeling.
Static and functional anthropometric data. Scaling techniques. Use of percentiles in design. Types of design.
Ergonomic work system design: principles and guidelines.
WORK SYSTEM DESIGN
Work-related musculo-skeletal disorders. General classification and main risk factors. Methods and tools of risk assessment.
Manual Material handling. Checklists and postural observation tools. NIOSH lifting equation. Snook & Ciriello Tables.
Upper limb disorders. Hand intensive tasks. The OCRA method.
Legislation and standard overview for risk evaluation in manual material handling (ISO 11228; EN 1005).
AAWS and EAWS ergonomic methods. Main structure and examples.
WORK MEASUREMENT
Principles and brief history of Time and Motion Studies. Estimation and Observational Methods.
Predetermined Motion Time System: origin, MTM and MOST Platforms. Outlines on MTM 1 and MTM-UAS: main structure and examples.
HUMAN MACHINE INTERFACES
Principles of human-machine interaction. Mental workload and human error.
Displays and controls: types and functions. Design principles for compatibility and comprehension. Standard and guidelines.
Usability of tools and equipments. Human modeling
Delivery modes
Class tutorials consist in the analysis of case studies and exercises for risk assessment method application.
Lab computer modules are dedicated to the ergonomic software Siemens Jack
Texts, readings, handouts and other learning resources
Documentation in help is prepared and distributed by lecturer.
Suggested books:
A Baracco, G Destefanis "Manuale di Ergonomia Industriale" CSAO
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
Assessment and grading criteria
The exam consists in a written and an oral test. In the written test, students will be asked to solve a couple of exercises similar to those assigned during class tutorials, regarding risk assessment method application, biomechanical models, work measurement time codes and interface design.
The oral exam will cover the didactic material taught in the course; during the colloquium, students will have to prove an overall understanding of the basic ergonomic principles.
