Bayesian g – Type Control Chart

Ketan A. Gajjar, Manharlal N Patel


Binomial and Poisson distribution are used in attribute control chart. For rare event data the g–type control chart based on geometric distribution is used. In this paper, we have developed Bayesian g–type control chart. Control limits False Alarm Rate (FAR) and Average Run Length (ARL) are derived on the basis of predictive distribution and then compared them with the results obtained under classical method. The Bayesian method gives larger values of the average run length and smaller values for the false alarm rate.
