SIL Analysis Data Model

The following diagram shows how the families used in an SIL Analysis are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of the each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

You can see that records in the following families are linked directly to an SIL Analysis:

Human Resource : Stores information about the people who will participate in the analysis as SIL analysis team members.
Reference Document : Stores the URL path to a document that is external to GE Digital APM and contains reference information related to the SIL analysis.
Instrumented Function : Stores information about the instrumented functions of the safety instrumented system that you are analyzing.
Logic Solver : Stores information about the safety instrumented systems that you are analyzing.

Additionally, Logic Solver) records and Instrumented Function) records are linked to one another through the Has IF relationship. In addition to the relationships described above, an SIL analysis includes records in the families that are linked to the Logic Solvers and Instrumented Functions.
