Date: Saturday, September 21, 2019 – Sunday, September 22, 2019
Time: 8:00 AM – 5:00 PM

The PHM Society offers an updated two-day intensive short course titled, PHM Fundamentals and Case Studies— From Monitoring/Sensing to Fault Diagnosis/Failure Prognosis and Case Studies, on PHM tools, methods, applications and case studies on September 21-22 in Scottsdale, AZ, USA right before the PHM19 conference. This follows from the first offering at the PHM14 conference in Fort Worth, TX with 48 attendees and regular ratings of 4/5. It was also run in 2015 in San Diego, 2016 in both Bilbao, Spain and Denver USA, in St. Petersburg, USA in 2017 and Philadelphia in 2018. And Utrecht, Netherlands in July 2018.

As in the previous offerings, the course will be taught by recognized international experts in the PHM field and will cover the current state of the art in PHM technologies, sensors and sensing strategies, data mining tools, CBM+ technologies, novel diagnostic and prognostic algorithms as well as a diverse array of application examples/case studies. It is addressed to engineers, scientists, operations managers, educators, small business principals and system designers interested to learn how these emerging technologies can impact their work environment.

Through a lecture (with Q&A), networking and workshop format with
specialist experts, participants will:

1. Establish a baseline for defining the extent and capabilities of PHM,
   specifically needs and organization
2. Identify specific details of PHM Applications (metrics, sensors, cost
   benefits, reliability) and PHM Methods (diagnostics, prognostics, data
   driven methods and uncertainty)
3. Identify issues and needs and a way forward including Continuing
   Professional Development
4. Examine case studies of PHM applications across diverse domains to
   identify solutions and impacts
5. Plan a PHM application in two mini workshop settings with expert group
   leaders

Note: A PHM Society Certificate can be provided for 1.4 Continuing Professional Development Units to each participant completing the course, on request.

Course Preparation

1. Background reading and references: http://www.phmsociety.org/references/documents/recommended-reading

2. Workshop topic: We will work in small groups on small realistic
   problems: Day one: developing PHM requirements- needs, metrics and on
   the second day- data and modeling approaches, operational issues. You
   are encouraged to bring a problem statement from your organization:
