Sistema de control de Inventarios multicriterio difuso para repuestos.

Inventory control has become one of the most worked topics in the academy in collaboration with the industry due to the high representation of product storage costs and the costs associated with lost sales due to not having product availability at the time of demand. This article presents a proposal for the inventory control problem of the most representative items of a spare parts warehouse, where more than one criterion must be considered. The methodology applied was initially based on the realization of a classification of the items through the use of diffuse AHP (FAHP), where important criteria related to the characterization of the type of items, such as total cost and criticality, were taken into account. with this, the most representative groups of items were identified, then a second classification was made to identify within these groups the critical articles for the control system. Subsequently, a demand analysis and the respective forecast for the items classified as type A were carried out. Finally, the proposal for the application of the continuous inventory control policy (s, Q) is presented, taking into account the analysis of the policies used for the spare parts and is validated by a case applied to a sugar mill. Among the main results of the investigation is the identification of those most important references for the mill considering multiple criteria, allowing to establish an inventory policy that minimizes the cost and meets a level of service previously defined by the organization.
