Abstract: Inventory classification using ABC analysis is one of the best methods employed extensively in the enterprises. Domestic and foreign scholars are researching ABC analysis referring to only one criterion, while the situation considering multiple criteria for inventory classification has been rarely presented in the literatures. In this paper, we propose a novel inventory classification model of ABC analysis for multiple criteria, which considers more about the influences of weights values of inventory items. The proposed model not only incorporates linear programming model, but also contains nonlinear model. Comparing our proposed model with the AHP method, then through solving the model and analyzing the conclusions, we get a better solution by considering weights values of inventory items. At last, an example is given to illustrate the proposed model, which is more flexible and representative, and better provides decision-making basis for inventory managers.
