The RAMS 2021 was delayed from January 2021 to May 2021 but in an in-person format. We made the following three presentations.

• Age-based maintenance scheduling for flowmeters with multiple failure modes and covariates by Ying Liao, Yisha Xiang, and Elias Keedy.
• Time-based preventative maintenance policies for circuit breakers with multiple failure types by Will Wascom and Yisha Xiang.
• An Introduction to Probability Models in Reliability and Maintainability, by Yisha Xiang, and Rong Pan (one of the RAMS’ core tutorials)
