Spare parts security strategy
Classified spare parts management
Key / Critical / General spare parts hierarchy management, with inventory configured according to risk and delivery cycle.
Spare parts for minor and major repairs
High-frequency maintenance components are tiered with fail-safe components to increase the recovery rate on site.
Dynamic inventory optimization
Dynamic adjustments to spare parts stocks and priorities based on health and failure trends.
Rapid redeployment strategy
Regional warehouses work with the field to increase efficiency in the allocation of critical spare parts.
Spare parts full process management
Retrospect the life cycle of spare parts, from warehousing, access to replacement, and retrospect.
