摘要

The article develops an adaptive multiple dependent states (AMDS) sampling inspection plan based on the mean lifetime quality characteristic that follows non-normal distributions, viz., exponential and Lindley distributions. This plan measures the quality of the lot by its mean ( \(\mu \) ). We have estimated the optimal plan parameters of the proposed technique using nonlinear optimisation approaches, considering the acceptance and rejection/limiting quality levels. We have compared the sample sizes of our proposed sampling plan with those of the existing multiple-dependent-state (MDS) sampling inspection plan and the traditional single-sampling inspection plan for the variable. Finally, we have used a real-world dataset and implemented our proposed plan to evaluate its efficiency.
