Human Factors Engineering
… the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data, and other methods to design in order to optimize human well-being and overall system performance.
Definition adopted by the International Ergonomics Association and the Human Factors and Ergonomics Association

Human Performance and Safety In Various Domains
Aviation: aircraft accidents Medicine: patient injuries and mortalities Manufacturing: defects Power Generation and Distribution:
blackouts Surface Transportation: auto/truck accidents Water Transportation: boat/ship accidents Workplace: occupational injuries etc.

Human Factors Engineering
considers Human Factors, factors that influence human performance, Individual Factors, e.g.,
sensory cognitive physical
Group Factors , e.g., composition organization dynamics
Task Factors, e.g., number nature procedure
Equipment Factors, e.g., display colors control placement and dynamics Tools geometry
Environment Factors, e.g., illumination temperature vibration
in an attempt to understand and improve human performance and safety so as to improve system performance and safety.
IE 366
13
Human Factors Engineering
learns of the effects of human factors on human performance and safety through
Experience (often bad) Research
and develops and applies principles and guidelines to the design of
Equipment, e.g., displays controls tools workstations
Procedures Job performance aids , e.g.,
manuals checklists memory aids
Training programs Selection programs

6-person teams (assigned by instructor) Start with Statement of Need (common) Develop requirements, design, implement
(computer aided model), evaluate Work System: worker(s) equipment work processes
Follow WSE process Write regular progress reports Write final report Give final oral presentation
