Accessing Safetygoal information in FMEDA Sheet with individual metrics

Question

Hi,
I would like to access the information on which safety goal is relevant for certain "sub-components" which are linked via the effect relation to the components evaluated in DC-worksheets with individual metrics with javascript.

To my understanding the information is effectively distributed in the "safetyGoal" property of the "worksheet", the "safetyRelatedFor" of the "component" and "evaluatedFor" of the "failuremode".

I can access the length of "safetyGoal" and "evaluatedFor" via "size()" and thus run via a for loop through the object and access the information this way.

How can I access the Information for "safetyRelatedFor"?

Thank you in Advance!

David, I of course could delete the article, but the question to some extend makes sense indeed to me.

So I pharse an answer instead, and you can decide whether you still want to delete it :-)

If you have a DC worksheet with just one goal, you can access the metrics directly for example worksheet.totalSpfFailureRate or even worksheet.getTotalSpfFailureRate().

If you have multiple safety goals, you cannot access a property but have to call an operation for each safety goal for example:

worksheet.getTotalSpfFailureRate(sg);

So something like:

// Output the DC metrics (per sheet, per safety goal)
var dcWorksheets = finder.findByType(Metamodel.dc.DCWorksheet, true);
dcWorksheets.toArray().forEach(function(dc, index) {
	console.log("4. DC {0} has {1} safety goals", index, dc.safetyGoal.size());
	dc.safetyGoal.toArray().forEach(function(sg, index) {
		console.log("4.1 SG {0} has total SPF {1}", index, dc.getTotalSpfFailureRate(sg));
		console.log("4.1 SG {0} has total LF {1}", index, dc.getTotalLmpfFailureRate(sg));
	});
});

Happy Scripting

Hi,

sorry I had a really silly mistake in a different part of the code that caused the error and confused me quite a bit. The above question does not make any sense.
Could you please delete/close the topic?
