Standardization of description for expert's opinion during weapon reliability evaluation under small sampling test
Zhang Jin-huai · Journal of Aerospace Power · 2007
Based on the characteristics analysis of expert's opinion in reliability engineering in aerospace field,the article presents the standardization description for three types of fuzzy description,viz.probability description,expert marking method,and subjective language description method.In addition,the prior distribution foundation on expert's opinion was carried out.In this article,the standardization models of general prior distribution,the weighted method based on expert's uncertainty,and maximum entropy method are presented.It is useful for getting the prior distribution from expert's opinion in reliability engineering when filed test data are small samplings and Bayes method is used.
