—Network security is a major issue affecting SCADA systems designed and deployed in the last decade. Simulation of network attacks on a SCADA system presents certain challenges, since even a simple SCADA system is composed of models in several domains and simulation environments. Here we demonstrate the use of C2WindTunnel to simulate a plant and its(More)
Virtual evaluation of complex command and control concepts demands the use of heterogeneous simulation environments. Development challenges include how to integrate multiple simulation engines with varying semantics and how to integrate simulation models and manage the complex interactions between them. While existing simulation frameworks may provide many(More)
Modern Network Centric Operations drive the complexity of Information Fusion and Command and Control (C2) Systems. Driving this complexity further is the interplay dynamics of the human element, information systems, and communication networks. The lack of low-cost realistic experimental context limits the testing, evaluation, and further development of(More)
Virtual evaluation of complex Cyber-Physical Systems (CPS) with a number of tightly integrated domains such as physical, mechanical, electrical, thermal , cyber, etc. demand the use of heterogeneous simulation environments. Our previous effort with C2 Wind Tunnel (C2WT) attempted to solve the challenges of evaluating these complex systems as-a-whole, by(More)
Service-Oriented Architectures (SOAs) are increasingly being used for designing and building large-scale networked and distributed systems. Catering to the complex and dynamically varying needs of business applications/clients, these systems must usually be realized by dynamically composing a variety of network-available services. Evaluation of large-scale(More)
Cyber-Physical Systems (CPS) [1] are engineered systems that require tight interaction between physical and computational components. Designing a CPS is highly challenging [2] because these systems are inherently complex, need significant effort to describe and evaluate a vast set of cross-disciplinary interactions, and require seamless meshing of physical(More)

What is the original contribution of this work? The primary contribution of this paper is the use of a meta-modeling framework to provide model-based rapid integration of multiple heterogeneous simulation platforms into a single HLA-based virtual environment. Why should this contribution be considered important? Simulation of heterogeneous environments is(More)
Modern planning and scheduling systems are capable of dealing with the size and complexity of many real world problems. However, mission critical planning is still often done by humans. Even if only a couple of plans are produced (" Master Plan " and " Plan B "), human experts evaluate multiple alternatives, think of contingencies , consider the likelihood(More)
