AI Technical Summary
Traditional tool inventory management fails to fully consider the actual frequency of tool use and fluctuations in production demand, resulting in redundant backlogs or supply shortages in inventory management, making it difficult to achieve an effective balance between cost control and production assurance.
By constructing a tool database, classifying tools into consumable and special-purpose categories, and adopting a minimum inventory strategy, combined with quota rolling adjustment, dynamic inventory forecasting, and full life cycle monitoring, dynamic maximum and minimum inventory algorithms are established to manage tool procurement and cost monitoring, ensuring continuous production while reducing inventory levels.
This approach achieves the goals of reducing inventory levels, increasing corporate operating profits, reducing capital occupation, and improving the precision of inventory management and cost control while ensuring production continuity.
