Abstract: In this article, we introduced an attribute control chart based on SkSP-R sampling inspection plan when lifetime of units follow the half normal distribution (HND). 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. Presented tables are explained in well manner to understand the presented theory. Graphical representation is also done to compare the Shewhart control chart and proposed control chart. A simulation study and a real life example are considered to show the application of proposed control chart.

Keywords: control chart; half normal distribution; acceptance sampling inspection plan; simulation.
