Bayesian Test Procedure of Lifetime Performance Index for Exponential Distribution under Progressive Type-II Censoring

M. F. Liu, H. P. Ren

Abstract


The lifetime performance assessment is important in the service (or manufacturing) industries. Lifetime performance index is used to measure the potential and performance of a process, where L is the lower specification limit. In this paper, firstly, we propose the critical interval and the Bayesian test for to assess the lifetime performance of products based on the conjugate prior distribution and squared error loss function under the exponential distribution with the progressive type-II censored sample; secondly, an example is given to illustrate the use of the testing procedure under given significant level. Moreover, the new testing procedure is to determine whether the product performance adheres to the required level.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
