Acceptance sampling plans based on truncated life tests for weighted exponential distribution

Communications in Statistics - Simulation and Computation, 2015
ABSTRACTGupta and Kundu proposed a new class of weighted exponential distributions using the idea of Azzalini. In this article, we develop an acceptance sampling plan for the weighted exponential distribution under a truncated life test. For various acceptance numbers, consumer’s confidence levels and values of the ratio of the experimental time to the

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 ...

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.

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.

Acceptance sampling plans based on truncated life tests for LOG-EIG distribution

2016 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM), 2016
In the article, the plans of acceptance sampling for log-EIG distribution are established while the lifetime test is truncated at the pre-assigned time. The smallest size of sample to guarantee the provided median lifetime, the operating characteristic functional value of the plans and the risk of the producer are given.

ACCEPTANCE SAMPLING PLAN BASED ON TRUNCATED LIFE TESTS FOR RAYLEIGH DISTRIBUTION

This paper addresses the problem of designing an acceptance sampling plan for a truncated life test where the lifetime of the product follows a generalized Rayleigh distribution. The study identifies the minimum sample sizes needed to ensure the specified mean life for various acceptance numbers, confidence levels, and ratios of the fixed experiment ...

Double Acceptance Sampling Plan for Time-Truncated Life Tests Based on Half Normal Distribution

Economic Quality Control, 2016
AbstractIn this work, we investigate a double acceptance sampling plan (DASP) based on truncated life tests when the lifetime of a product follows the half normal distribution. By fixing the consumer’s confidence level, the minimum sample sizes of the first and second samples needful to assert the specified mean life are calculated.

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 ...

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 ...

Time Truncated Life Tests Using the Generalized Multiple Dependent State Sampling Plans for Various Life Distributions

2019
This chapter presents the designing of the generalized multiple dependent state sampling (GMDSS) plans for the various statistical distributions. We will present the design of GMDSS sampling when the failure time follows the gamma distribution, Burr type XII distribution and the Birnbaum-Saunders (BS) distribution.
