Enhancing the availability and reliability of power plants through macroergonomics approach

Abstract

This paper describes an integrated macroergonomics model for operation and maintenance of power plants. Statistical tests on questionnaire survey data shows the importance of total human factors on job pressure. An integrated approach based on interview methods, questionnaires, information flow analysis and anthropometric and environmental assessment is discussed. The integrated approach provides detailed knowledge about ergonomics, management and safety conditions of power plants. Highlight of this study is the employment of a total system approach based on integration of the traditional human factors engineering and macroergonomics considerations. The approach of this study is applied to an advanced thermal power plant.
