Using Linear Programming to Optimize Control Panel Design from an Ergonomics Perspective

Abstract

Linear programming (LP) for optimization of control panel layouts has been incorporating ergonomic constraints into models to reduce reaching distances required for control panel use since the 1960's. These algorithms have used a panel's frequency of use, distance from user, and transition distance as basic model variables. A new variation of the LP model for control panel design is proposed that modifies the layout from single point semidry to dual point semidry in terms of design using anthropometrics. The proposed model was applied to the design of a twelve-panel board of six-inch square panels. The model was able to take into account design factors such as control sequence, alignment, and clustering, as well as direct hand access. The resulting control panel solution minimized the reach and movement distances required by an operator. Results suggest that LP optimization can be used to construct “ergonomically designed” control panels that limit MSDs incidence and severity.
