"Intelligent Decision Support for Marine Safety and Security Operations"

Abstract: With the increasing traffic in ports and its vulnerability to the illegal activities and threats, large volume surveillance has become a challenge. This problem is even more aggravated considering the fact that Canada has the largest coastline in the world and, consequently, managing the employment of resources under changing environment is an issue yet to be resolved. Therefore, an Intelligent Decision Support System for a Marine Security Operations Center (MSOC) is presented here. Considering the robustness and scalability of any such system, the goal is to improve coordination in emergency response services during critical situations, including detection and prevention of illegal activities. This can be done through system’s decentralized control structure, dynamic resource configuration management and task execution management under uncertainty. The proposed model is described in abstract functional and operational terms based on the Abstract State Machine (ASM) paradigm and the CoreASM open source tool environment for modeling dynamic properties of distributed mobile systems.

12:30 - 1:20 - Dr. Eric Winsberg, Philosopher of Science, University of South Florida

"Reflections on the Verification and Validation of Computer Simulations"

It is common practice in the simulation community to distinguish between verification and validation. Verification is said to be the process of determining the extent to which the solutions generated by the computer simulation model approximate the solutions to the original mathematical model equations. And validation is said to be the process of determining the extent to which a computer simulation model is an adequate representation of a target system. In this presentation I argue that this distinction is not as clean as it is often thought to be. I also argue that this has important implications for how we think about the epistemology of simulation, and the relationship between theories and the world.
