Reliability Information Fusion Method Based on Evidence Theory

Abstract

For high reliable products, because it’s higher cost and longer lifetime, the reliability analysis and evaluation is difficult in engineering. It becomes necessary to recur to information fusion technique. However, how to use the multi-source reliability information, there are not an effective way in reliability assessment. The aim of the paper is to obtain a new method which can incorporate different type reliability information, such as reliability field data, reliability test data and reliability analysis information. Using evidence theory to address epistemic and aleatory uncertainty in reliability analysis.
