Materials Requirements Plan Engineered
OptimalSPARES™ Wiki
Strategic and critical spares, your materials requirements plan engineered. Hold the right part, in the right quantity, for the right reason, and release the capital tied up in the rest. This is spares and materials optimisation: the physical side of the maintenance strategy, where a stockout costs a shutdown and an overstock costs the balance sheet.
Spares optimisation
The stockout and overstock trade-off, and why criticality drives it.
ReadMethod and toolStocking models
EOQ, reorder point and safety stock, with a live stocking calculator.
ReadMethodCriticality
Why the consequence of a stockout, not part cost, sets the stock.
ReadWhere it sits on the platform
OptimalAvailability Studio™ decides the maintenance tasks and the criticality, OptimalSPARES™ makes those tasks executable by holding the parts, and OptimalTREND™ turns a remaining-life estimate into a just-in-time order. Spares is where the strategy meets the storeroom.
What OptimalSPARES™ does
OptimalSPARES™ cleans and classifies the materials data, links parts to assets through the bill of materials, ranks each spare by criticality, and sets the min, max and reorder point that hit the target service level at the lowest stock. It distinguishes the fast consumable from the slow insurance spare and models each correctly, and it writes the result back to the ERP, ready for materials requirements planning. The outcome is less capital in the store and fewer stockouts at the worst moment.
Where to start
- New to it? Start with spares optimisation, then criticality and the stocking models.
- Want the maths? Stocking models has EOQ, reorder point and safety stock, and a live calculator.
- Building a case? Value and deployment covers the value and the inputs. Open the demo at demo.spares, or see every app at apphub.optimalworld.org.
