In a previous post I gave a brief overview of inventory management. All companies are interested in reducing inventory as long as the result is no lost sales, customer service issues, or material shortages. One way to reduce total inventory is to consolidate DC’s or warehouses. This is due to the fact that safety stock is held at each location, so fewer locations equals less safety stock. The effect on inventory levels by adding or eliminating warehouses can be calculated by using the Square Root Rule. I am attaching a summary of the Square Root Rule and an example.
