This paper aims at evaluation of the quality performance of multi-stage manufacturing system during transients. A Markovian method is constructed in order to evaluate transient propagation of quality at multi-stage manufacturing systems which have remote quality information feedback. With the derived Markovian model, analytical expressions of estimating quality metrics in transients are provided, such as settling time and dynamical quality. Case study at a factory is given to demonstrate the derived approach. The conclusions drawn illustrate the applicability of transient quality evaluation of multi-stage systems.
