GOL'20 : 2020 5th International conference on logistics operations management (GOL), October, 28-30, 2020, virtual : proceedings P. 79-84Abstract: This work proposes an ABC-XYZ-type analysis modified with observed merchandise deficit. The deficit is determined by right censoring. This manuscript proposes to account for right censoring in the ABC-XYZ analysis. The modified ABC-XYZ analysis updates many important quantities including projected income, the coefficient of variation, and the Kaplan-Meier estimator. An illustrative example shows that the classical ABC-XYZ algorithm underestimates a merchandise value when deficit was observed; magnitude of the coefficient of variation is also underestimated. The new method corrects this bias and recalculates overall profit and the coefficient of variation.
