N2  - The ABC-XYZ analysis is widespread in modern
business, especially in the inventory control, marketing and
 logistics. It is used for classification of the assortment
 depending on the revenue or profit of sales of the enterprise
 according to the ABC-part of the method and the amount of
 sales for the XYZ-part. The paper proposes a modification of
 the ABC-XYZ analytical technique for the case of the presence
 outliers in the data. The modification of the method allows
 identification of the outlier by means of the Grubbs’ test. After
 excluding the outliers, the mean and the standard deviation of
 the truncated sample are used to re-estimate average sales,
 recalculate revenue and coefficient of variation, regroup and
 finally help decrease costs by means of better forecasting and
 changing strategies of inventory management, e.g. choosing
 more appropriate replenishment systems for products and
 avoiding bullwhip effect in a supply chain. The new technique
 was applied to a simulating data set and demonstrated the
 results of classification that differ from the classical one. The
 suggested method must be considered as a preferable
 technique for classification as it is based on more reliable and
 accurate data and robust estimation of mean value and
 standard deviation
