Thank you Rufina. Your comments are great, but they are not the three inventory control models. We have many inexpensive items that are used frequently in the manufacturing of aerospace products. We use the fixed-order quantity model. We determine the level of inventory we want to keep. We have a minimum and a maximum quantity. Once it reached the minimum quantity, we order a set amount that will bring us back to the maximum amount. Please give another example of this inventory control model
