A demerit-fuzzy rating system, monitoring scheme and classification for manufacturing processes

作者：

Highlights：

• Fuzzy weights properly reflect defect severity and impact control charts’ performance.

• Two fuzzy numbers can be ranked into: larger, rather larger, rather smaller, and smaller.

• Our demerit-fuzzy approach can classify a process into multi-intermittent statuses.

• Thorough quantitative conditions to classify a manufacturing process are proposed.

• A case study in monitoring garment-stitching defects is used to elucidate our approach.
