Dear APO community
I'm currently implementing the new APO functionality which performs the ABC / XYZ analysis. I was able to simulate easily the expected result in an Excel file for the ABC part but the behavior of the XYZ part remains for me a mystery. I used the variance coefficient as method in the XYZ profil. I get the theorical formula of this coefficient on a website specialized
Coefficient
of variation = Standard deviation (√(((D-D1)²+ (D-D1)² … (D-Dn)²)/n-1) / Mean
average demand (D1+D2+..Dn / n)
I customized the thresholds in the XYZ profil according to the calculated coefficients in my Excel file but I don’t get the expected result when I perform the analysis.
Does anyone already successfully experiment this XYZ analysis and give me a feedback about the XYZ formula ?
What means the value maintained in XYZ profil ? Upper limit ?
Best Regards
Vincent
