IE 366 IE 366: Work Systems Engineering Introduction

IE Industrial and Manufacturing Engineering What is Industrial Engineering? What is Manufacturing Engineering? What are the desirable attributes of the Industrial/Manufacturing Engineer?

IE Industrial/Manufacturing Engineering (IME) complex system integration and operation

IE Work What is work? Why is it important to IMEs? What is a Work System? What are the challenges for Work Systems Engineers (i.e., IMEs who design work systems)?

IE 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

IE 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.

IE 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 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
