Cumulative Sum (CUSUM) chart s are statistical tools used to monomor swost in production processes. They are particarlyy efuttive for detecting small shifts that may note be visible with traditional control chart. Implementing CUSUM charts can help maintain product quality and process stability.

Understanding CUSUM Charts

A CUSUM chart track the cumulative sum of deviations from a daceult value overtime time.

Előnyök Of UsingCUSUM Charts

Compared to traditional control chart s, CUSUM chart s are more senitive to smalll shifts in the proces. They provide quicerer detectioon, reducing the risk of producing defective products. Additionally, CUSUM charts can be customized to detect shifts of specific sizes, makingg versatile for varioutectioon environments.

A CUSUM Charts végrehajtása

To implement a CUSUM chart, instrucish a value and acceptable limits. Colcert process data and calculate the cumulative sum of deviations from the the teme to observe trends. When the cumulative sum crosses predigied prefeds a potential shift the process.
