Optimal order quantity is the scientifically calculated purchase or production volume that minimizes total inventory-related costs, including ordering expenses, warehousing costs, capital tied up in stock, and the risk of shortages. It is derived from consumption rates, demand variability, supplier lead times, and cost structures, ensuring that inventory replenishment remains economically balanced while maintaining service reliability.
Characteristics:
- Minimizes total inventory cost
- Balances order frequency and stock levels
- Prevents unnecessary capital lock-in
- Improves inventory planning precision
- Reduces risk of shortages and overstocks
