The funnel experiment: The Markov‐based SPC approach

摘要: The classical funnel experiment was used by Deming to promote the idea of statistical process control (SPC). popular example illustrates that implementation simple feedback rules stationary processes violates independence assumption and prevents conventional SPC. However, did not indicate how implement SPC in presence such rules. This pedagogical gap is addressed here introducing a rule results nonlinear which traditional methods cannot be applied. proposed method Markov-based SPC, simplified version context-based method, shown monitor modified well.
