GROUP ACCEPTANCE SAMPLING PLAN APPLICATION FOR VINYL CHLORIDE DATA USING GENERALIZED INVERTED KUMARASWAMY DISTRIBUTION

The current paper discusses the group acceptance sampling plan based on truncated lifetimes when the lifetime of an item follows the generalized inverted Kumaraswamy distribution (GIKum). For a given group size, the minimum number of groups and the acceptance number required are determined for specified consumer's risk and the test termination time. The values of the operating characteristic function for various quality levels are calculated and the minimum ratios of the true average life to the specified life at given producer's risk are achieved. The techniques are illustrated by using real-world data.
