ASSURED EVALUATIONS OF SYSTEM RELIABILITY WITH INCOMPLETE INFORMATION CONCERNING RELIABILITY OF ELEMENTS (O GARANTIROVANNYKH OTSENKAKH NADEZHNOSTI SISTEMY PRI NEPOLNYKH SVEDENIYAKH O NADEZHNOSTI ELEMENTOV),
Abstract
It is conventional to consider the complete characteristic of the reliability of a system (or element) to be function P(t), i.e., the probability of troublefree operation of the system (or element) during time t. Reliability theory examines the following basic operations on the laws of distribution of P(t), at any value of t: sequential combination of n elements; parallel combination of n elements; combination with replacement of elements; and averaging with respect to random operating conditions. The exponential law of reliability has acquired exceptional significance. If this is not used in estimating element reliability there naturally rises the question of how many and what characteristics of P sub e(t) must be known to give well-founded estimates of system reliability; the minimum number of such characteristics is of course desired. The specific problem in this paper is to explain what may be guaranteed in the sense of knowing P(t) in combinations of the above types if some of the listed characteristics are known about Pe(t).
