A robot vakuum eleaner factory has decided to classify its inventories through multicriteria ABC analysis considering its inherent uncertainties. The inventories are evaluated based on several eriteria which are identified as Monetary value $($C$1),$ Storage space $($C$2)$ and Lead time $($C$3).$ In the analysis, initially the criteria weights will be computed through fuzzy AHP method. Pairwise comparison judgments are collected from experts using a linguistic scale. Then, the linguistic evaluations are converted to their corresponding triangular fuzzy numbers as in Table $1.$
