Abstract: Most of the optimal design procedures for the cumulative sum (CUSUM) and exponentially weighted moving average (EWMA) charts require a shift to be specified for which the chart is optimal in detecting. Such a chart would perform well at the intended shift but it will be increasingly insensitive if the shift moves further away from the intended shift. The specification of a shift may not be practical because in reality, the shift that occurs is more likely to be random. Thus it does not make good sense to design a chart this way. We propose simultaneous schemes which do not require any specification of a shift in advance. These simultaneous schemes comprise a few CUSUM or EWMA charts including a Shewhart chart that run simultaneously. We conduct a comprehensive study of the simultaneous schemes and develop a simple design procedure for determining the chart parameters. Such a scheme is found to be sensitive in detecting a range of shifts and has better overall run length performances as compared to individual charts and other simultaneous schemes.
