Failure Mode Models Failure Mode Modeling refers to the approach whereby the failures of a system are identified and their corresponding effects form the connectivity of the model. This approach became popular largely as a result of the reliability block diagram.

Types of Failure Mode Models There are several kinds of Failure Mode Models that each address different aspects of engineering: Fault Trees Reliability Block Diagrams Failure Mode Dependency Models Failure Modes and Effects Analysis (FMEA, FMECA) It can also be noted that the following modeling approaches also support the addition of failure modes: Dependency Models Hybrid Diagnostic Model
