Abstract
Statistical process control methods for a process with multiple streams are developed and compared to traditional solutions. New methods maintain the simplicity of the group control chart while improving on traditional limitations. A model that allows correlation between the streams is described and a simple control strategy is recommended. Performance comparisons are provided.
