Effective inventory management is essential for maintaining a lean supply chain. Proper calculations help reduce excess stock, minimaze costs, and improwize overall efficiency. Thie article converses key calculations used to o optimize inventory levels.

Economic Order Quantity (EOQ)

EOQ określa te kwoty, które są wymierne, aby zminimalizować koszty wynalazków, w tym koszty związane z inventory, w tym koszty związane z porządkiem i kosztami holding.

Reorder Point (ROP)

Te Reorder Point indicates when new stock should be ordered to prevent stocks. It consider lead time disd:

Safety Stock Calculation

Safety stock acts a buffer against variability and lead time delays. It i s calculated based on differenciations andd sumlier reliability.

A Combn formula is:

Xi1; Xi1; FLT: 0 Xi3; Xi3; Safety Stock = Z × σd × IIILead Time Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;
