A system is provided for integrating failure data for different failure analysis layouts. The system includes a data validator and layout engine. The data validator is configured to validate failure analysis data for a complex system including a plurality of systems. The failure analysis data includes failure data identifying failed systems, and design data describing the complex system and possible failures of at least some of its systems. In this regard, the data validator is configured to perform one or more consistency checks between the failure data and design data to thereby integrate the failure data for a plurality of different failure analysis layouts. The layout engine is in turn configured to selectively generate and communicate any one or more of the plurality of different layouts of the failure analysis data, with at least some of the failure analysis data being shared between at least some of the different layouts.

Failure analysis validation and visualization

A method for zone analysis. A zone is identified in a three-dimensional physical model of a vehicle. The three-dimensional physical model includes geometry information and location information for physical components. An effect of an undesired operation of a group of components in a zone within the three-dimensional physical model of the vehicle is identified based on the three-dimensional physical model of the vehicle and a logical model of the vehicle including a logical architecture linking logical components to each other. Logical components in the logical model are mapped to the physical components in the three-dimensional physical model of the vehicle.

A failure-effect validation system includes an effects modeler configured to develop a cumulative effects model for failure modes of the complex system, and by which a model of the complex system is extendible to form an extended complex-system model. The effects modeler is also configured to develop search targets each of which includes logical expressions of notable hazards and other factors that contribute to the cumulative effects, such as crew workload, safety margin and/or physiological effects. A model analysis system is configured to perform an automated analysis using the extended complex-system model and search targets, and in which the automated analysis includes a graph search of possible states of the extended complex-system model to locate search targets. And the effects assessment system is configured to selectively generate a layout of failure analysis data including at least a portion of the extended complex-system model and results of the automated analysis.
