EVALUATION OF RESPONSE CHARACTERISTICS OF CHAIN SAMPLING INSPECTION PLANS.
Abstract
This report gives an evaluation of Chain Sampling Inspection Plans pertaining to response characteristics, i.e., their ability to respond to an abrupt change in the process fraction defective, p. Average run length (ARL) is used as a measure of the response. The process model and a number of ARL's of different type are defined; a general derivation of ARL is given; and the ARL's and a number of contrasts between these ARL's are obtained and discussed to compare ChSP plans with non-cumulative plans as well as among themselves. The gain in inspection efficiency (reduction in average sample size, ASN) for two-stage chain sampling plans appears to be promising compared with the extra lag in detecting process changes that results from the use of the cumulative procedure.
