RELIABILITY ANALYSIS OF COMPLEX MAN-MACHINE SYSTEM TECHNIQUE UNDER KNOWN DISTRIBUTION LAWS OF TIME TO COMPONENT FAILURE

Abstract

Complete information on the component reliability of the complex man-machine systems is obtained in the case of availability of the component uptime distribution laws and of their parameters, as well as of the information on the components independence. Under the violation of one of these conditions it should be assumed that the information on the complex man-machine system (MMS) component reliability is incomplete which complicates in whole the calculation and analysis of the MMS hardware reliability. Based on the long-term author’s studies, a problem-solving technique for the hardware reliability analysis of various man-machine systems is developed on the basis of the interval average theory tenets. The technique takes account for the limitation of the source information, system component dependence, and the possibility of describing uncertainty. Examples of the reliability analysis in the event of information on the component reliability independence, in its absence, and under the man-machine restorable system reliability are presented.
