The difference between these two methods is that the EPQ model assumes the company will produce its own quantity or the parts are going to be shipped to the company while they are being produced, therefore the orders are available or received in an ...
EOQ applies only when demand for a product is constant over a period of time (such as a year) and each new order is delivered in full when inventory reaches zero. There is a fixed cost for each order placed, regardless of the quantity of items ordered; an order is assumed to contain only one type of inventory item.
Compared to the EOQ equation, there is a factor d/p introduced. This is due to the fact that when we produce a component while it is used in downstream production at the same time, inventory levels will not reach the same peak as when we order the components from a supplier and receive the batch at a single point in time.
The (Q,r) model is a class of models in inventory theory. [1] A general (Q,r) model can be extended from both the EOQ model and the base stock model [ 2 ] Overview

By the time the inventory level reaches zero towards the end of the seventh day from placing the order materials will reach and there is no cause for concern.
