In the context of model-based product and system design, the capability to assess the impact
of potential component faults, undesired interactions, and fault propagation is important for …

Abstract System-based approaches such as Functional Resonance Analysis Model (FRAM)
are developed to model the complex interactions of system variables and their performance …

While cyber–physical system sciences are develo** methods for studying reliability that
span domains such as mechanics, electronics and control, there remains a lack of methods …

Complex engineered systems can carry risk of high failure consequences, and as a result,
resilience—the ability to avoid or quickly recover from faults—is desirable. Ideally, resilience …

Emergent behavior is a unique aspect of complex systems, where they exhibit behavior that
is more complex than the sum of the behavior of their constituent parts. This behavior …

This paper represents a step toward a more complete frame-work of safety analysis early in
the design process, specifically during functional modeling. This would be especially useful …

This paper presents a framework to compare the resiliency of different designs during the
conceptual design, when information about implementation details is unavailable. We apply …

Fault detection and identification in mechatronic systems with complex interdependencies
between subsystems is a very active research area. Various alternative quantitative and …

The Functional Failure Identification and Propagation (FFIP) risk assessment method has
been proposed in past research for the evaluation of early system designs. Extensions of the …

This paper presents the use of data clustering methods applied to the analysis results of a
design-stage, functional failure reasoning tool. A system simulation using qualitative …
