Chapter 25 A New Method to Determine Equipment Testing Period Based on Mission Reliability

摘要

To avoid the problem caused by classical strategy of fixed testing period, in which equipment failure may happen before testing, a new method to determine testing period was put forward. In this method, mission reliability of interval between arbitrarily neighboring twice testing was regarded as constant or transformed into specified area; according to this principle, an optimal model to calculate equipment testing period was established; in this model, optimal variables included parameters of testing times, mission reliability time offset, and testing interval. A more reasonable and scientific equipment testing period can be received by solving the model. Finally, an example was given to demonstrate how to apply the method, and the results show that mission reliability of interval gradually descends by using fixed testing period, and rational testing period should be variational.
