Stochastic modelling of human-performance reliability

A stochastic model is developed to quantify the reliability of human performance. The model provides closed-form mathematical expressions into which multiple factors affecting the reliability of man-machine system can be incorporated. Three elements of man-machine systems are combined to form the framework for modeling: random task arrivals, transient human performance characteristics (detection of task arrivals, performance accuracy, performance time, etc.), and operational requirements of the system. Simulation and numerical models that could be developed within this framework are indicated.<
