Published	09/15/2024	The stock level at which a new order is placed to replenish inventory.
Published	09/15/2024	The amount of stock ordered when the reorder point is reached.
Published	09/15/2024	The situation where customer demand exceeds the available stock, and orders cannot be fulfilled immediately
Published	09/15/2024	In the flow of an inventory system, this is the step where the system starts with an initial inventory level
Published	09/15/2024	In the flow of an inventory system, this is the step where customers place orders, and the inventory is reduced to meet demand.
Published	09/15/2024	In the flow of an inventory system, this is the step where if the inventory falls below the reorder point, an order is placed with the supplier
Published	09/15/2024	In the flow of an inventory system, this is the step where if inventory is sufficient, no action is taken
Published	09/15/2024	A delay between placing the order and receiving the new stock
Published	09/15/2024	The inventory continues to deplete based on demand during lead timeTrueFalse
Published	09/15/2024	In the flow of an inventory system, this is the step where the order arrives, ad the inventory level is increased by the order quantity
Published	09/15/2024	In the flow of an inventory system, this is the step where the process repeats as demand continues, and inventory levels are managed over time
Published	09/15/2024	Standard policies used to manage inventory
