What happens to the inventory*? *) Data of engine #7781905-00, high runnerHow to control the inventory?: How to control the inventory? Inventory Position Time Max. Inventory Position Inflate shipments: Avg. forecast (x weeks) * inflation factor Deflate shipments: Avg. forecast (x weeks) * deflation factor (almost) constant shipment quantities !Which Part analyzed?: Which Part analyzed? Part Engine #7781905-00 High runner Policy # of weeks for average: 3 Max. Inventory Position: 2509 Inflation/deflation: 1.8% Performance Overview: Performance Overview How does ship-to-average perform for this engine:Shipment Comparison: Shipment Comparison ship-to-forecast ship-to-average (shipment adjustment: 66%) (shipment adjustment: 14%) = shipment quantity changes more than 10% compared to previous one Shipment adjustments happen in 14% of all shipmentsWhat’s next?: What’s next? Goals achieved! Optimized policy works. But how robust is the result? What are the trade-offs? How do the 3 parameter… # of weeks for average Max. inventory position Inflation/deflation factor … influence the result? Sensitivity Analysis: # of weeks for average: Sensitivity AnalysisSensitivity Analysis: Sensitivity Analysis Max. Inventory Position: Sensitivity Analysis: Sensitivity Analysis Inflation/deflation factor:Summary Table : Summary Table Advantages: Advantages Small cost reduction compared to current ship-to-forecast policy Less variation in order quantities Less bullwhip effect Easier operations for Spartanburg/ Wackersdorf/ upstream suppliers Facilitates negotiation with transportation partner Limitations of the study: Limitations of the study Simulation vs. reality Restricted original data sets provided Small number of parts considered Constant shipment frequency assumed (once per week)Recommendations: Recommendations Run pilot to check performance: pick high runner with relatively stable demand over time Analyze larger set of parts Evaluate cost savings upstream Evaluate trade-off between higher savings and increasing expediting Q&A: Q&A You do not have the permission to view this presentation.
