Ergonomic Performance and Evaluation of Worksystem: A Few Applications

Abstract

Application of ergonomic principles provides a standardized approach for the analysis of a worksystem with emphasis on evaluation of interaction between human(s), machine(s), and environment, as a first step toward exploring the enormous potential and concepts of ergonomics at workplaces. The objectives of the study are manifold: to identify and characterize the ergonomic variables for a given worksystem with regard to work efficiency, operator safety, and working conditions, and to design a comprehensive ergonomic performance indicator (EPI) for quantitative determination of the ergonomic status and maturity of a given worksystem. The study consists of three phases: preparation and data collection, detailed structuring and validation of EPI model. Identification of ergonomic performance factors, development of interaction matrix, design of assessment tool, and testing and validation of assessment tool (EPI) in varied situations are the major steps in these phases. The case study discusses in detail the EPI model and its applications.
