Markovian Time-Delay Sampling Policies

摘要

Sampling procedures are considered for monitoring the output of a production process. Sampling rates are allowed to depend on one of several levels of acceptance or rejection, sampling less frequently when the process is in control. The problem is formulated as a simple Markov process whose properties yield the expected values and the variances of the number of samples and the numbers of various types of adjustments to the process. Computations are given in support of the economic design of variable sampling policies of this type. (Author)
