SAMPLING PLANS BASED ON TRUNCATED LIFE TEST FOR LOGISTIC FAMILY OF DISTRIBUTIONS

2023
In this article, we develops optimal sample size for acceptance number (zero and one) for single and double sampling plans by fixing consumer’s risk and test completion time, with the assumption that, the life of the item follows logistic family of distributions (i.e.

Attribute Control Charts for the Weibull Distribution under Truncated Life Tests

Quality Engineering, 2015
ABSTRACTIn this article, an attribute control chart is proposed when the lifetime of a product follows a Weibull distribution, which is based on the number of failures from a truncated life test. The coefficients of the proposed control chart and the test duration are determined so that the average run length when the process is in control is close to ...

Methods for Fitting the Right‐Truncated Weibull Distribution to Life‐Test and Survival Data

Biometrical Journal, 1988
AbstractThis paper develops mathematical and computational methods for fitting, by the method of maximum likelihood (ML), the two‐parameter, right‐truncated Weibull distribution (RTWD) to life‐test or survival data. Some important statistical properties of the RTWD are derived and ML estimating equations for the scale and shape parameters of the RTWD ...

Acceptance sampling based on truncated life tests for generalized Rayleigh distribution

Journal of Applied Statistics, 2006
This paper considers the problem of an acceptance sampling plan for a truncated life test when the lifetime follows the generalized Rayleigh distribution. For different acceptance numbers, confidence levels, and values of the ratio of the fixed experiment time to the specified mean life, the minimum sample sizes necessary to ensure the specified mean ...

Improved acceptance sampling plans based on truncated life tests for Garima distribution

International Journal of System Assurance Engineering and Management, 2018
The Garima distribution is proposed as a model for lifetime. The problem of acceptance sampling plan when the life test is truncated at a predetermined time is studied. For various acceptance numbers, different confidence levels, and different values of the ratio of the fixed experiment time to the specified average life, the tables of the minimum ...

SOME RESULTS ON TRUNCATED LIFE TESTS IN THE EXPONENTIAL CASE

1953
Abstract : Life tests are considered which are truncated so that n items a re placed on test; an advance decision requires that the experiment be terminated at min (X sub r sub o, sub n, T sub o), where X sub r sub o, sub n is a random variable equal to the time at which the r sub o 'th failure occurs and T sub o is a truncation time beyond which the ...

Acceptance sampling plan based on truncated life tests for exponentiated fréchet distribution

Journal of Statistics and Management Systems, 2013
Abstract In this paper, exponentiated Frechet distribution is considered as a model for a life time random variable when the life test is truncated at a pre-assigned time. The operating characteristic functions values of the suggested sampling plans and the corresponding producer's risk are obtained.

A group acceptance sampling plan for truncated life test having Weibull distribution

Journal of Applied Statistics, 2009
In this paper, a group acceptance sampling plan for a truncated life test is proposed when a multiple number of items as a group can be tested simultaneously in a tester, assuming that the lifetime of a product follows the Weibull distribution with a known shape parameter.

ACCEPTANCE SAMPLING PLANS FOR BIRNBAUM-SAUNDERS DISTRIBUTION UNDER TRUNCATED LIFE TESTS

International Journal of Reliability, Quality and Safety Engineering, 2005
For modeling fatigue data, satatistical distributions are often used because the lifetimes of a fatiguing material can vary due to manufacturing variation or random flaws in the material. One of the popular distributions to describe the number of stress cycles until failure, or analogously, time to failure is the Birnbaum-Saunders distribution. If the

A truncated life test in acceptance sampling plan based on exponentiated exponential distribution

2016 International Conference on Emerging Trends in Engineering, Technology and Science (ICETETS), 2016
In this paper, an attempt for designing an acceptance sampling plan with the truncated life test when the life time of an item follows exponentiated exponential distribution with known shape parameter. The design parameters that portray minimum sample size and operating characteristic function for the sampling plan with various quality levels are ...
