Human Systems Integration (HSI): Psychological Influences in Design Produce Exceptional Operator Performance

摘要

During the past two decades, that portion of human factors and ergonomics work centered in materiel acquisition settings has been largely subsumed into the larger context of "human systems integration" or HSI - where such work has taken its rightful place as an important part of systems engineering and management processes (Booher, 2003). Human systems integration focuses on ensuring all human elements are properly accounted for in research and design initiatives when developing large configurations of people-operated equipment and systems. HSI evolved from practical applications of established human-oriented design principles espoused in the fields of engineering psychology, human engineering and macro-ergonomics - disciplines predominately pioneered in military acquisition programs since World War II. HSI is also now more widely employed in procurement of large new civilian systems of people and machines in such diverse applications as new transportation, communication, finance and banking, and homeland security systems design, as well as the diverse designs of hospital surgical wards and treatment centers. This article describes the derivation and basic premises of incorporating engineering psychology into HSI. It also presents a few practical contemporary examples of the application of psychology in HSI
