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 ...

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 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 ...

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 ...

Acceptance sampling plan for truncated life test having generalized Pareto distribution

Life Cycle Reliability and Safety Engineering, 2019
In this study, repetitive acceptance sampling plan for truncated life test is developed for that situations in which the lifetime of the product follows the generalized Pareto distribution. The parameters of the proposed plan such as sample size, acceptance numbers and probability of lot acceptance are determined when the producer’s risk, consumer’s ...

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 Plans for Half-Normal Distribution Under Truncated Life Tests

American Journal of Mathematical and Management Sciences, 2013
SYNOPTIC ABSTRACT In this work, we study acceptance sampling plans for half-normal distribution when the lifetime experiment is truncated at a preassigned time. For various acceptance numbers, confidence levels, and values of the ratio of the experimental time to the specified average life, we obtain the minimum sample size required to ensure a certain
