【Abstract】 This paper presents a synthetic control chart that is an integration of the shewhart chart and the conforming run length chart. we found from intensive performance tests that the synthetic control chart produces smaller out of control average run length that the shewhart chart for analyze of δ while than the -EWMA chart for δ greater than 0.8σ.更多还原
