Gray model for the operating reliability of man-machine system

In industries as manufacturing fields, service companies, the operating reliability of man-machine system is very important, which is a great part of the system reliability. To getting high reliability of system and administer operation procedure effectively, a quantitative analysis should become a necessary method. Since the operation sequences of the machine vary according to time, person and place, and then the model of this process should be complex that could reflect the characteristics of operator behavior, the machine functions and the environment effect. Aiming at a new quantitative analyzing model for evaluating man-machine operating system and the related process, and some typical gray characteristics of this process, such as dynamic response, multi-parameters and being related to psychology and physiology, the theory of gay system is utilized in this paper. Then a gray model to analyze the operating program is established, and the relevant mathematics method is introduced. Using this model and analyzing method, the operating reliability of man-machine system can be evaluated; a simple example is adopted to explain the detail in this paper. According to the quantitative result of research about man-machine system, the behavior of system can be forecasted. Finally it can influence the design of operating interface of industrial equipment and improve the level of industrial management.
