If the sample or population has vague, inaccurate, unidentified, deficient, indecisive, or fuzzy data, then the 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 for Weibull distribution under neutrosophic statistics (NS) has been developed. We developed improved single and double group-sampling plans based on the NS. The proposed design neutrosophic plan parameters are obtained by satisfying both producer’s and consumer’s risks simultaneously under neutrosophic optimization solution. Tables are constructed for the selected shape parameter of Weibull distribution and various combinations of neutrosophic group size. The efficiency of the proposed group-sampling plan under the neutrosophic statistical interval method is also compared with the crisp method grouped sampling plan under classical statistics.

如果样本或总体具有模糊，不准确，不确定，不足，犹豫不决或模糊的数据，则可用的抽样计划可能不适合用于决策。在本文中，基于中智统计（NS）的Weibull分布，基于时间截断寿命测试，开发了一种改进的小组抽样计划。我们基于NS制定了改进的单组和双组抽样计划。通过在中智优化解决方案中同时满足生产者和消费者的风险，可以得到拟议的中智设计计划参数。为选择的威布尔分布形状参数和中智群大小的各种组合构建表。
