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.

Model based analysis of a three-dimensional zone in an aircraft

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.

System and method for assessing cumulative effects of a failure

A failure analysis system for monitoring sub-system failures in an aircraft that comprises a plurality of sub-systems, the aircraft having a plurality of functions, wherein each function is available when one or more associated sub-systems is operating correctly. The failure analysis system comprising: a plurality of monitors for monitoring the status of one or more sub-systems of the aircraft and determining if a failure has occurred; a memory arranged to store a list of a plurality of flight phases or operating modes to be completed by the monitored system and data associating one or more of the functions with each flight phase or operating mode; and a processor in communication with the monitors and the memory and arranged to model the response of the sub-systems to a failure determined by the monitors to identify which functions required by the flight phases or operating modes are degraded or are not available.
