Contributions on designing acceptance sampling plans for truncated life test

Abstract

Basic ideas, terminologies and literature related to truncated life newlinetest acceptance sampling plans are given in the first chapter.In the remaining chapters, single and newlinedouble acceptance sampling truncated life test plans are designed assuring mean under Frechet, newlineassuring median under odd Weibull and assuring percentile lifetime under Gompertz, Kumaraswamy newlineinverse exponential, Marshall-Olkin Kumaraswamy generalized exponential and Marshall-Olkin newlineKumaraswamy generalized Lomax distributions. The designing principles followed in the thesis are newlinebased on i. minimum ASN at the specified consumer s confidence level ii. a newly proposed method newlinewhich involves minimum total cost at the specified consumer s confidence level and iii. incorporating newlineminimum average sample number at consumer s quality with two specified points on the operating newlinecharacteristic curve. newlinei) Major objectives : The present research work proposes single and double acceptance newlinesampling plans for life testing when the lifetime of the product units follow different lifetime newlinedistributions.
