Fuzzy AHP TOPSIS Methodology for Multicriteria ABC Inventory Classification

Table 8

Sensitivity analysis of the ABC multicriteria classification.

Classification	Number of subgroups
	Initial solution	25% each criterion	100% AS	CR-WI (35%) + AS-DT (15%)
A	9	7	7	8
B	35	37	36	36
C	45	45	46	45

AS: annual sales, DT: delivery time, CR: criticality, and WI: warehousing impact. Notes. Table 8 shows how the results obtained in the TOPSIS method vary by varying the weight of the criteria, where the groups classified as A continue to hold in the different scenarios.
