EQUIPMENT SPARE PART INVENTORY OPTIMIZATION METHODS AND SYSTEMS

摘要

Methods and systems for optimizing spare part inventory for equipment are described. In one embodiments a method of processing equipment maintenance report data to optimize spare part inventory for equipment comprises: identifying equipment maintenance reports relating to failed parts in the equipment report data; calculating a time-to-failure for each failed part in the equipment maintenance reports relating to failed parts and thereby generating time-to-failure data for a plurality of equipment-part combinations; for each equipment-part combination of the plurality of equipment-part combinations, fitting the time-to-failure data to a statistical distribution; estimating failure rates for each equipment-part combination of the plurality of equipment-part combinations using the respective statistical distributions; and optimizing spare part inventory for equipment using the estimated failure rates.
