Resumen
Esta investigación trata sobre la simulación de sistemas dinámicos para la determinación de niveles de reposición y de servicios en inventarios, la cual nos guiamos de un modelo de simulación de inventario donde (Q) es el nivel de reposición y (D) la demanda. Para hallar la utilidad neta existen dos tipos de fórmulas. Si la demanda es menor o igual al nivel de reposición entonces: Utilidad neta es igual a la utilidad bruta menos el costo de retención el nivel de reposición menos la demanda. Si la demanda es mayor al nivel de reposición entonces: Utilidad neta es igual a la utilidad bruta menos costo de incumplimiento el nivel de reposición menos la demanda. Con este algoritmo pudimos simular cada mes la utilidad neta de un producto de una empresa comercializadora de productos plásticos. Durante la simulación, se obtuvieron datos específicos del producto y se hicieron 30 simulaciones del modelo para 24 meses de trabajo. Los resultados confirman la utilidad del modelo para determinar los niveles de reposición y de servicio del producto.
This research deals with the simulation of dynamic systems for the determination of replacement levels and services in inventories, which we are guided by an inventory simulation model where (Q) is the replacement level and (D) the demand. There are two types of formulas to find net income. If the demand is less than or equal to the replacement level then: Net profit is equal to the gross profit minus the retention cost the replacement level minus the demand. If the demand is greater than the replacement level then: Net profit is equal to the gross profit minus the default cost the replacement level minus the demand. With this algorithm we were able to simulate each month the net profit of a product from a company that sells plastic products. During the simulation, product-specific data was obtained and 30 model simulations were made for 24 months of work. The results confirm the usefulness of the model to determine the levels of replacement and service of the product.
