Short Run SPC for Batch Textile Processes
topic
Short-run SPC adapts conventional control chart methodology for batch dyeing, printing, and finishing processes with insufficient runs per product to establish product-specific control limits, using deviation-from-nominal and Z-MR charts that standardise measurements across multiple products onto a common dimensionless scale enabling multi-product process monitoring on a single chart.
Role
Extends statistical process control benefits to the batch-oriented jobbing production environments typical of commission dyehouses and specialty finishers where conventional SPC requiring 20 to 25 points for limit calculation is impractical for short production runs of diverse product types processed on shared equipment.
