The Enterprise Resource Planning's (ERPs) are computer systems that help companies to standardize operations integrating business information. For inventory management these packages have some models for control and management purposes that require the definition of several parameters, which in many cases are set arbitrarily by the inventory managers ignoring the impact that these have over the inventories, costs and service levels. In order to help inventory managers to define, in a more technical way the parameters of inventory control policies, this paper presents a framework for decision support system for inventory management area. The model's outline includes the underlying inputs, a general description of the morel and the expected outputs, which allow companies to define more technically all the information that an inventory control model requires to improve the effectiveness of the system.
