In this paper, a multi-objective Inventory model is developed in a fuzzy environment. The primary objective is to minimize the average total cost per unit and the secondary objective is the minimization of total warehouse required. We assume that both objectives are fuzzy in nature. The model is assumed in two forms: In the first model, we assume the primary objective function to be in fuzzy form and in the other one, the holding cost, the setup cost and the space required are also considered to be in imprecise form. The modeling formulations are solved numerically and results from different models are compared.
