Fault Propagation Model Representation in POOM

The above analysis and model is useful to enable us to draw the structure of the database of the failure data group and to automate the hazard evaluation practice. But in order to do that it is essential to define the fault propagation model and its representation in the plant design model using the above analysis results. 

Fault propagation model elements (FPMEs) are as stated earlier PEC, PV, NAS, POS, FLD, and OPR. These elements can be mapped to the plant object oriented model (POOM) as per table 3-6. 

Fault Propagation Model Element (FPME) Representation in POOM 

PEC Physical equipments are represented as object, class, or package. If PEC represents a complete CGU then it is mapped to package, otherwise it is mapped to object or class. 

OPR Operation is mapped to the operation, which is associated with class or object. Operation can accept parameters to perform the step-by-step functions.
