Causal history analysis of complex system dynamics
Complex system arises as a result of inter-dependencies between multiple components. The nonlinear interactions occurring in the system usually lead to emergent behaviors. The emergence prevails in many natural systems, such as the fractal dynamics of stream chemistry, the chaotic behavior of …

Uncertainty-Integrated Surrogate Modeling for Complex System Optimization
… to the potential lack of quantitative models of system behavior. These capabilities not only enable the efficient design of complex systems, but is also essential for the effective analysis of physical phenomena/characteristics in the different domains of Engineering, Material Science, Biomedical …

A risk dynamics model of complex system development
The development of complex systems is a challenging endeavor which has captured the attentions of scholars and practitioners alike. Throughout the decades, numerous methods have been proposed to help manage such development efforts more effectively and efficiently. Some of these methods, such as …

Observations of designer behaviors in complex system design
The design of large-scale engineering systems requires design teams to balance a complex set of considerations. Formal approaches for optimizing complex system design assume that designers behave in a rational, consistent manner. However, observation of design practice suggests that there are …

Complex System Simulation Framework for SharedAugmented Reality Applications
Complex systems perspectives are a tool that give an individual the ability to better understand the outcomes of actions on both the environment and other actors within the system. These perspectives are rarely given an opportunity to develop within educational environments, and many students lack …

Detecting Misbehaviour in a Complex System-of-Systems Environment
Modern systems are becoming increasingly complex, integrated and distributed, in order to meet the escalating demands for functionality. This has given rise to concepts such as system-of-systems (SoS), which organise a myriad of independent component systems into a collaborative super-system, …

Contextual Framework of Communications Functions Supporting Complex System Governance
<p>The purpose of this research was to develop a systems theory-based contextual framework of communication functions supporting complex system governance using an inductive research design. Communication, as one aspect of Management Cybernetics (communication and control for effective system …

Systems Theory Based Architecture Framework for Complex System Governance
<p>The purpose of this research was to develop a systems theory based framework for complex system governance using grounded theory approach. Motivation for this research includes: 1) the lack of research that identifies modeling characteristics for complex system governance, 2) the lack of a …

A generalized framework for complex system design and management
This thesis outlines a structured framework for complex system design and management. There have been and continue to be many efforts focused on defining the elusive generic System Engineering Process. I suggest one reason why industry, government, and academic efforts have had limited success in …

Impact of complex system behavior on seismic assessment of RC bridges
… methods. However, several characteristics of complex RC bridge response are not yet fully understood. The challenge of assessing risk posed to bridges with irregular or curved geometry subjected to multi-directional loading is non-trivial. The effect of the resulting combined interactions on …

A methodology for the measurement and evaluation of complex system designs
Most complex systems incorporate hardware, software and humanware elements operating synergistically under conflicting functional and nonfunctional objectives. These systems are usually embedded, mission-critical, performance-critical, real-time, distributed, highly integrated, heterogeneous, cost …
