Strategy of quality monitoring and control for a multi-stage manufacturing process based on error propagation

Abstract:

To reduce the influence of current allocation strategy of monitoring points for control system of process quality and the influence of error propagation of quality indicators among processes, a decision-making model of quality monitoring and control for a multi-stage manufacturing process based on dynamic programming method is built up. The example analysis proves the validity of the model, and the results show that the model will benefit for monitoring and control and make the strategy formulation more reasonable.
