Create a fault tree document in the Safety Analysis Manager and retrieve the FaultTree object.

myTreeDoc = safetyAnalysisMgr.newDocument("fault-tree");
myFaultTree = myTreeDoc.FaultTrees(1);

Add two basic events to the tree.

myTopGate = myFaultTree.Gates(1);
event1 = createEvent(myTopGate);
event2 = createEvent(myTopGate);

Get the failure model for each event.

myFailureModel1 = event1.FailureModel;
myFailureModel2 = event2.FailureModel;

Retrieve the failure model parameters for each event, then specify the Q and W parameter values.

myParameters1 = myFailureModel1.Parameters;
myParameters1.Q.Value = 0.02;
myParameters1.W.Value = 0.02;
myParameters2 = myFailureModel2.Parameters;
myParameters2.Q.Value = 0.01;
myParameters2.W.Value = 0.01;

Get the EvalConfig object of the fault tree document, then set the mission time to 2.

myEvalConfig = myTreeDoc.EvalConfig;
myEvalConfig.MissionTime = 2;

Evaluate the fault tree.
