This is a simple paper outlining how to use some Risk Analysis Techniques with Network Engineering to obtain quantitative results. An attempt to turn network engineering from an artful guessing game into a science.
Gates are the devices that link all of the events together and provide the logic on how the lower events contribute to the occurance of the ones it links further up the tree. A gate represents an event which is being further developed. Basic logic functions from boolean algebra serve as gates, but there are only five that are used. Of these, the AND and OR gates get by far the most use.
Transfer gates don't provide any additional logic, but allow a fault tree diagram to be broken down into multiple diagrams. Transfer gates are labeled to link them together.
