USMA 2021 Corrosion Data Analysis Study: Assessing Maintenance Data Quality for H-60 and HMMWV Platforms
Abstract
Corrosion is estimated to account for over 20 billion dollars' worth of maintenance parts and labor each year in the Department of Defense (DoD). The DoD's Corrosion Policy and Oversight (CPO) directorate is charged with developing and implementing a long-term strategy aimed to improve military readiness and operational efficiencies for DoD equipment and infrastructure through effective corrosion prevention and control technologies. The Maintenance and Availability Data Warehouse (MADW) was developed to improve understanding of the corrosion problem, seeking to inform corrosion policy and funding decisions. However, MADW data relies on raw maintenance data collected by the Services at the organizational and depot levels. For CPO to make data-informed decisions to effectively mitigate and manage corrosion across the Services, it must first have high quality data from users and maintainers. CPO seeks to understand the maintenance data quality for the H-60 Blackhawk, which is an aviation platform common to the Army, Navy, and Air Force. This work focuses on data completeness and consistency, using approximate string matching to assign scores to each maintenance record. The Jaro-Winkler similarity algorithm was selected to assess the closeness of match between string data fields for maintenance entries.
