Single-stage and two-stage total failure-based group-sampling plans for the Weibull distribution under neutrosophic statistics

Abstract If the sample or population has vague, inaccurate, unidentified, deficient, indecisive, fuzzy data, then available sampling plans could not be suitable to use for decision-making. In this article, an improved group-sampling plan based on time truncated life tests Weibull distribution under neutrosophic statistics (NS) been developed. We developed single and double NS. The proposed design parameters are obtained by satisfying both producer’s consumer’s risks simultaneously optimization solution. Tables constructed selected shape parameter of various combinations group size. efficiency statistical interval method is also compared with crisp grouped classical statistics.
