Fehlentscheidungen bei Ersatzteilbestandsverwaltung (Überbestände vs. Lieferengpässe)
Definition
Semiconductor maintenance operations require stocking critical spare parts (motors, actuators, vision systems, thermal modules) to minimize repair lead times. Without predictive wear-out forecasting, maintenance teams must choose between two costly errors: (1) Overstock to avoid shortage risk—tying up cash in slow-moving inventory and incurring storage/obsolescence costs; (2) Lean inventory—risking multi-day delays if a critical component fails and must be ordered from equipment manufacturers (often located globally, increasing lead time to 5-10 days). Predictive maintenance algorithms analyze equipment data to project wear-out timelines by days/weeks, enabling just-in-time spare parts procurement.
Key Findings
- Financial Impact: Typical fab: €2M-€5M annually in excess spare parts carrying costs (storage, insurance, obsolescence, opportunity cost on working capital) + €500K-€2M in production delay costs when unavailable parts extend repair windows by 24-72 hours
- Frequency: Quarterly inventory planning cycles; parts lead times range 1-10 days depending on origin
- Root Cause: Manual maintenance rules lack real-time equipment condition visibility. Inventory decisions based on historical failure rates (average-case) rather than predictive wear-out forecasts (specific-case for each machine instance). No closed-loop feedback mechanism to adjust stocking levels based on actual vs. predicted failure patterns.
