Modeling Event Trees in RENO

Event Trees are excellent tools for assisting analysts in assessing risks (or any type of event) and the probabilities of different possible outcomes. Event trees rely on an effective structured framework within which the different events can be laid out and the possible outcomes of the sequence of events can be investigated. Event trees are widely used in many fields such as finance, economics, reliability, risk assessment and numerous other probabilistic types of analysis. They help in creating a holistic picture of the risks and rewards associated with each possible course of action. They very are popular due to their simplicity. This article introduces event trees and presents an approach for modeling them using RENO.

Reliability Basics

Minimal Cut Sets

Traditional solution of reliability block diagrams and fault trees involves the determination of the so-called minimal cut sets. Minimal cut sets are the unique combinations of component failures that can cause system failure. Specifically, a cut set is said to be a minimal cut set if, when any basic event is removed from the set, the remaining events collectively are no longer a cut set.

 

Minimal cut sets have traditionally been used to obtain an estimate of reliability for complex reliability block diagrams (RBDs) or fault trees that can not be simplified by a combination of the simple constructs (parallel, series, k-out-of-n). BlockSim has the capability to derive an exact analytical solution to complex diagrams and therefore does not utilize the cut sets methodology. Cut sets are provided in BlockSim for interested users.
