REV EW OF RECENT DEVELOPMENTS OF STATISTICAL THEORY• OF AGING CONCEPTS,.'

Abstract

The vital needs of modem science and technology insistantly put forward the task of developing a systematic approach to the study of any phenomena and processes occurring in the world. It is quite natural therefore, that such an approach is also required in studying the problem of rei iability of technical products and system.

The theory of reliability is a branch of statistical technology that deals with the general regularities to observe in the design, testing, manufacture, acceptance and use of products to obtain the maximum efficiency of the •products. Reliability is a measure of the degree of successful performance of a functional under the required conditions of operation. The quantification of reliability, therefore, resolves itself into how success may be measured or, conversely, what measure can be attached to failure. Reliability plays a significant role in modem life where reliability is utilized in many fields, in production, planning, and design. In addition, the application of reliability can be seen in engineering, social, biological, sciences, maintenance, and biometrics.
