To bolster the efficiency and performance of maintenance work in manufacturing—maintenance being one of the key components to ensuring successful long-term operations—it is becoming increasingly necessary to ensure that maintenance operations are capable of seizing on analysis techniques from prognostics, health-monitoring, and related disciplines. Despite a surge in availability for low-cost sensing and data processing generally, the bulk of available knowledge on any given maintenance workflow will currently exist within historical records, via Maintenance Work-Orders (MWOs). Additionally, despite burgeoning standards in sensing and the related analysis, there is a dearth of similar standards scoped to MWOs. To that end, this paper addresses standards needs in MWOs, specifically, MWO data collection and storage, MWO data cleaning and parsing, and MWO data analysis needs.
