Cyberstrategics

In my earlier post today, A Review of Zabbix - Zabbix Rules! (Part 2) I used the term “event precursor.”   Afterwords I thought “this is a nice event processing term, I wonder who used it before me?”

So, I did a bit of Googleing around and came up with this excellent paper where the term “event precursor” is used and illustrated, albeit in a slightly different context than how I used the same term.  Without further ado, here it is:

Early Event Detection – A Prototype Implementation by Michael Bell, Jamie Errington, Dal Vernon Reising, Dinkar Mylaraswamy, NOVA Chemicals Corporation and Honeywell Laboratories (circa 2002).

In the reference above, the EED use case discusses operational situational awareness and outage prediction. There are others instances in the prior art where the term “event precursor” is used in a similar context - the prediction of outages and other processing problems.

Abstract: NOVA Chemicals Corp. and Honeywell Laboratories have been working together to evaluate the effectiveness of an Early Event Detection (EED) prototype in a typical manufacturing environment. The role of an EED application is to augment the console operators monitoring behavior and situation awareness as well as provide them with a tool to reduce or avoid process upsets. The EED application uses robust mathematical algorithms to monitor the correlations in key process measurements and estimate the state or condition of the plant unit. In this paper, we will describe the major steps of the project – including the unit selection, data selection, modeling techniques, run-time platform, and user interface – that have been executed to drive the creation of a successful online application in a petrochemical facility. Though the evaluations have not been fully completed – the early results are that the EED prototype is a very effective means to enhance the monitoring of a plant and to help avoid potential manufacturing upsets.

Editorial Note:   SL Corporation has been known to create process visualizations similar to those illustrated in the referenced paper.
