نمودارهای کنترل g w m a و d g w m a برای مشخصه های کیفی وصفی

در نمودارهای کنترل با حافظه، سرعت کشف شیفت های کوچک فرایند بیشتر از نمودارهای کنترل شوهارت است؛ به طوری که در سال های اخیر نمودارهای کنترل میانگین متحرک موزون عمومی (g w m a) و میانگین متحرک موزون عمومی دوگانه (d g w m a)، کاراتر از نمودارهای میانگین متحرک موزون نمایی (e w m a) و نمودارهای میانگین متحرک موزون نمایی دوگانه (d e w m a) معرفی شده اند. این نمودارها غالباً برای پایش مشخصه های کیفی مت...

with probability 1 − o(1). Last time it was shown that almost surely d ≥ (1 + o(1))(log n/ log d̃), so we now concentrate on proving that this is also an upper bound. We will need three lemmas before attacking the theorem itself. We also mention that some technical details will be omitted, and we refer the reader to [1] for the full treatment. In particular, it is worth mentioning that this theo...
