Comparative Analysis of Maintenance Management Systems

Project Site: Daniel K. Inouye Solar Telescope (DKIST), Pukalani, HI

Mentors: Stephanie Guzman & Heather Marshall

Project Abstract:

A Computerized Maintenance Management System (CMMS) helps to enhance maintenance strategy through increasing the incorporation of assets or equipment into a preventive maintenance plan, and gathering relevant data to identify the occurrence and duration of component failures, as well as the impact of failure-induced downtimes on observing cadence.  This tool helps companies to achieve a more mature maintenance strategy that encompasses centralized access and linkage of maintenance information, including equipment history, work orders, scheduled maintenance, inventory, and inspections.  The staff of the Daniel K. Inouye Solar Telescope (DKIST), situated on Haleakala, Maui, are in the process of deciding whether their maintenance management system will run from Hippo or Eptura.  Currently, the maintenance approach leans towards reactivity, with a reliance on demand work orders, and a lack of centralized recording for repairs and inspections.  DKIST endeavors to transition towards a proactive and integrated maintenance approach.  To determine whether to continue using Hippo or switch to Eptura, I have constructed a trade study involving the management systems Hippo, Eptura Core, and Eptura Advanced.  Metrics were created based on the needs of DKIST, added capabilities provided by Eptura Core and Eptura Advanced, and risks associated with migrating to a new tool.  This study involved gathering the importance of criteria through a survey distributed to the staff of DKIST.  By comparing the collected data and creating a scoring system, DKIST will be able to make an informed decision regarding whether to retain Hippo or migrate to Eptura as their maintenance management system.
