The ASM consortium has carried out a survey in the US petrochemical industry and estimated the losses due to abnormal situtation. A percentage of these losses can be attributed to the poor performance of alarm systems. To put a positive spin on this- does anyone know of any material that outlines how to calculate the benefits of improved alarm management.

 

The Petrochemical industry uses any DCS for control and automation. Then the abnormalities can be listed down and the items which are causing for individual abnormality is listed down with necessary logic. These logics for all abnormalities are built in the DCS and annunciation with possible solution is initiated for the operator to take up the task in order to reduce the reaction time taken by the human being. Being a power plant man, what type of the problem will be there in executing the above idea, I may not know please.

I believe that Matrikon has done some work in this area. We use there product - ProcessGuard.

Thanks I am aware of this link to the design guideline, the cost-beneift analysis method suggested in the guideline is based on the cost of previous incidents. i.e. records of incidents need to be obtained which is not always possible. I'm looking basically for a statistical analysis type of approach the alarm rate reduction is justified in monetary terms.

Hi,

The following white paper from Plant Automation Services (www.pas.com) may be of interest:

http://www.pas.com/whitepapers/documents/amo white paper v8.pdf

I've not had a thorough read of it, but it does seem to present some methods for evaluating the economic benefits of alarm management.

What exactly do you mean by a risk matrix approach?
