In current scenario, big departmental stores used to work more efficiently with the items that can be substituted either with optimum order quantities or selling prices of the products. In this paper, the models are determined as the total profit maximization problem with uncertain finite budget fuzzy constraints thereby solved through a gradient based search technique- GRG (Generalized Reduced Gradient) method. The prices and optimal order quantities of substitutable items are obtained so that total profit for store owner is maximum.
