A systems approach to defining operator roles

This paper briefly describes the elements of a systems approach for defining the role of the operating crew of a nuclear power plant. A systems approach aims at solving the multifaceted and interrelated problems produced by complex man-machine systems. Through systems analysis and engineering, an organized and systematic approach to the proper allocation of roles between man and machine can be made. This approach is utilized here to develop a methodology for specifying the optimum role of the crew in a nuclear plant system and also defining the internal structure of the crew for the purpose of ensuring the safe and economic operation of the plant.
