Reliability Assessment Using Fuzzy Evidence Theory
Xingyuan Zhang, Hai Rong Xu, Da Min Cao, Sheng Hu · Applied Mechanics and Materials · 2012
Aiming at many uncertain factors in the reliability assessment of aircraft, a new approach to reliability assessment combining D-S theory of evidence and fuzzy theory was discussed. The concepts of inclusion degree and intersection degree of fuzzy sets were redefined, and fuzzy evidence theory was extended to the circumstance when the framework of discrimination is a continuous and in finite set. Finally, the practical assessment process was given in an illustrative example of aircraft system. The results show that the method is effective and reliable.
