Diseño de un modelo de gestión de producción e inventarios para la empresa ESP Filters

ESP Filters es una empresa que aplica procesos de importación y producción para la comercialización de filtros para vehículos a nivel nacional. Los productos importados corresponden a tres categorías de filtros: aire, aceite y combustible, mientras que los productos fabricados corresponden a los filtros de aire. La empresa está ubicada en el sector Fontibón en Bogotá, Colombia, la fuerza comercial de ESP Filters es el mercado nacional, sin embargo, ha estado explorando el mercado internacional en países latinoamericanos durante un año con más de 500 referencias.ESP Filters is a company that applies processes of importation and production for the commercialization of filters for vehicles nationwide.

Value of disruption information in an EOQ environment

We consider an infinite horizon, continuous review inventory model with deterministic stationary demand where supply is subject to disruption. The supply process alternates between two states randomly: one in which it functions normally (ON-period) and one in which it is disrupted (OFF-period). In this setting, we seek the value of disruption information which enables the buyer to place "disruption orders" at the beginning of OFF-periods. Utilizing renewal theory, we derive the total expected cost and characterize the optimal regular order-up-to level together with the order-up-to level for disruption orders. We also conduct an extensive numerical analysis and compare the results with the model with no opportunity of disruption orders. We observe that if the shortage cost is relatively high, and the disruption risk is significant (in terms of duration and/or frequency), placing a disruption order reduces the expected total cost significantly
