Abstract
We consider the a posteriori analysis of the reliability of electronic systems (RES) which is performed after production of an experimental batch of equipment to determine its reliability characteristics. These tests are necessary because at the design stage designer does not have the full apparatus of a priori information, which would allow to determine in advance the reliability indicators with sufficiently high reliability. An important source of gathering information about the reliability of the system is the product of the work of data collection in the course of their operation. There are two main types of the reliability tests. One of them - the standard test, which task is to estimate indicators of reliability. It is typical for high-volume products. Another type of test - control tests, which task is to verify compliance with the specifications of the system reliability index. The second test is devoted to this type of work. It is necessary to answer the question whether the characteristics of grade products (produced RESs) specify the requirements laid down specifications for the manufacture of the product. To solve this problem using the mathematical apparatus of the theory of statistical hypotheses. We consider two hypotheses: a hypothesis – mean time before failure – specifies the requirements of TU (good product); hypothesis – mean time before failure – alternative (bad product). The decision on the validity of a hypothesis is accepted by the rule of the Neumann – Pearson. The paper considers the procedure RES pilot lot testing procedure for [n, B, r] and identified the following indicators of reliability: MTBF; sample rate matching parameters specified by the manufacturer; risk assessment for the manufacturer of the test sample. From tests carried out it can be concluded that the sample in question complies with the requirements.
Keywords: electronic systems, test procedures, failure rate, the risk of the customer, the manufacturer of the risk, the average uptime, the duration of the test, Neumann - Pearson rule, criterion
