Chapter one: Guided tour of ergonomic design 15 Ergonomic criteria Ergonomic criteria are used to judge problem solutions and alternative designs. A variety of criteria are typically used in ergonomic design. Some relate to the job and others to human performance. One long-used criterion is speed or performance time. Speed is important to measurement of productivity, and it is almost everything in the design of sports products. For this reason, industrial operations are frequently time studied over several cycles of production.
Zadeh of the University of California at Berkeley conceived the idea of fuzzy set theory in the 1960s. Like many such ideas, it has taken time to find its way into applications. † For more detail, see the article by Lehto, House, and Papastavrou (2000). 3 Abstract control system. * People driving vehicles follow paths such as roads or factory aisles. Obstacles along these paths are avoided by making control changes. Servo-mechanisms follow the same general control theory even though corresponding elements, operating rules, and parameters differ.
People communicate to machines through input devices called controls. Switches, keys, and valves are examples of machine input communications devices. Communications from the machine to the person occur through displays of various kinds which are sensed by the human. Lights, mechanical devices, and computer monitors are examples of displays. This sequence of communications activities can be made faster and more accurate when the machine’s input and output devices are designed to be compatible with the human operator.
