Causal Analytics in IIoT – AI That Knows What Causes What, and When
practical example of Reliable Causal Analytics( rCA) applied to a floating production storage and offloading( FPSO) 1 vessel for an Oil & Gas company.
Crude oil, gas and water from the reservoir are separated on board the FPSO. Oil is stored on the facility in six pairs of tanks, before export to trading tankers. The vessel is designed to store 1.4 million barrels of oil and processes approximately 170,000 barrels of oil per day( bopd).

Au Sable’ s rCA approach has functioned in intelligence, defense and anti-terrorism applications for many years. The solution described in this article is the combination of advanced IoT Process Management from XMPro and the rCA AI algorithms from Au Sable.
ROOT CAUSE ANALYSIS BASED ON CORRELATION DOESN’ T WORK IN THE IOT ERA
Industrial RCA Background
Formal Root Cause Analysis for industrial applications started with the Total Quality Management( TQM) 2 movement advocated by Deming in Japan in the late 1980’ s and early 1990’ s.
Paul Wilson et al 3 described the root cause analysis process for Quality Management in detail during the TQM era.“ Root cause analysis is a method of problem-solving used for identifying the root causes of faults or problems. A factor is considered a root cause if removal thereof from the problem-faultsequence prevents the final undesirable outcome from recurring; whereas a causal factor is one that affects an event ' s outcome, but is not a root cause. Though removing a causal factor can benefit an outcome, it does not prevent its recurrence with certainty.”
Even though root cause analysis formally originated in TQM, it finds many applications in industrial environments: 4
� Safety-based Root Cause Analysis arose from the fields of accident analysis and occupational safety and health.
