Your distribution strategy will also be influenced by the location of the constraint. If you have chosen the customer-intimate, high service strategy, you may want to implement a replenishment/pull system to serve the market. Your buffering strategy will influence where inventory is located and the amount. For example, you may implement the TOC distribution replenishment system, with consignment inventories at retailers, regional inventories to serve those retailers, and a central warehouse to serve the regions. But if your products are make to order, this method would not make sense.
