Buffer Stock
Quantities of raw materials and finished goods held across the distribution network provide a hedge against demand variability. Management of supply chain inventory balances the cost of holding goods against the risk of stockouts and lost sales. Visibility into these levels allows planners to adjust production schedules and shipping routes in real time.
Efficient tracking prevents the accumulation of obsolete products.
Carrying Cost
Capital tied up in stored items represents an opportunity cost for the business. Storage fees and insurance add to the total expense of maintaining a large surplus. Just-in-time strategies aim to minimize these holdings by synchronizing arrivals with the exact moment of need.
Reliable data is necessary.
Distribution Dynamics
Positioning goods at different nodes in the network affects the speed at which a final order can be fulfilled. Hub-and-spoke models centralize the main volume while keeping smaller amounts closer to the end user. Seasonality requires a buildup of stocks months before a peak period to ensure the logistics system can handle the load.
Lead times for international freight often dictate the minimum amount of safety stock required at a port or warehouse. Unexpected events like strikes or weather delays test the adequacy of these reserves. Safety stocks dwindle.
