PHM Society Short Course: PHM Fundamentals and Case Studies

The PHM Society offers this 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 July 2-3 in Utrecht, Netherlands right before the PHME18 conference. This follows from the first offering at the PHM14 conference in Fort Worth, TX with 48 attendees and ratings of 4/5. It was also run in 2015 in San Diego, 2016 in both Bilbao, Spain and Denver US and in St. Petersburg, USA in 2017.

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 will be provided for 1.4 Continuing Professional Development Units to each participant completing the course.

Course Leaders: Prof. G. Vachtsevanos, Dr. Manuel Esperon Miguez and Dr. Karl Reichard

Course Presenters: European specialists using packaged PHM Society curriculum but presenting their own case studies and mini-workshop topics.

Course Administrator: Jeff Bird

Course Location: Utrecht, Netherlands

Course Fee: To be confirmed in the spring. Contact course administrator for more information.
