A New Type-I Censoring Statistical Algorithm for the Reliability Test

Abstract

The Type-I censoring test has the advantage of time control which makes it widely used in the engineering practice. The outputs of the current Type-I censoring statistical algorithm are the total test time and the receiving number of failures. However, the total test time has already been settled by the test profile under many circumstances. Furthermore, the current Type-I censoring statistical algorithm is unable to evaluate the system reliability when the number of failure is zero during the system reliability test. Aiming at the problems above, a new Type-I censoring statistical algorithm was proposed to calculate the number of failures to receive the results of the reliability test considering the fixed total test time. And an evaluation method for zero-failure system reliability evaluation was developed. Then an assistant software was built to implement the algorithm. At last, two practical cases showed the importance of the receiving number of failures which should be calculated in the test design stage before the reliability test begins. And they also proved the new algorithm and the software is effective and feasible.
