Abstract

The classical approach to the calculation of reliability characteristics is based on the probability distribution of time to failure. The system under consideration is accepted as a 'black box' which performs the required function until it fails. This paper presents an 'engineering' approach to the calculation of reliability characteristics which attempts to obtain the same results at the same time providing information about 'what is going on inside the box'. According to the new approach, reliability characteristics have been determined using the probability distribution of a relevant condition parameter which fully describes the condition of the system in every instant of operating time. It is applicable to those systems whose components fail gradually. This approach offers greater potential for practical application in maintenance theory. The proposed approach can also be used as a method for accelerated testing for reliability of engineering systems and their components.

'Reliability presents the ability of a system to perform required functions under stated conditions for a stated period of time. This may be expressed as a probability.
