Abstract: In this paper, we presented a SkSP-R sampling inspection plan based on attribute control chart for situations where units lifetimes follow log-logistic (LL) distribution. Control limits of proposed control chart are evaluated for different choices of parameters and also discussed the trend of control limits for better understanding of effect of parameters on control limits. The findings of the proposed control chart is listed in bullet points in description of tables section. The presented tables are explained in a good manner. A hypothetical situation is created by using simulated data to illustrate the working of proposed control chart. The application of suggested control chart is explained using a real-world scenario.
