Work system design with the ergonomic harmony framework for aging workforce

The general workforce is aging, especially in the Asian countries where most of the world's production operation is taking place, and it has indeed become one of the dominant issues in various sectors of industry all around the world. This paper develops a theoretical ergonomic evaluation and design model named 'Ergonomic Harmony Framework' for the aging workforce based on four existing approaches which are separately used to evaluate and solve the physiological, psychological, psychosocial and behavioral problems of human factors in a work system. A descriptive work system model and a mathematical framework specifically assessing this model are integrated for obtaining the harmony of the entire work system
