Simulation
Wednesday 10th November 2010, 1400hrs–1530hrs
Chaired by Ralf Siegfried Applications of Virtual Worlds to Command & Control Center Design and Analysis Mr. Philip Monte, Naval Undersea Warfare Center (Division Newport), United States With the rapid emergence and evolution of Virtual Worlds (VWs) over the past three years, the Naval Undersea Warfare Center (Division Newport) has investigated and applied multiple applications of this technology across the undersea warfare (USW) domain. VWs are revolutionizing the approach to submarine system design compared to legacy methods. For example, the virtual environment enables all stakeholders to remotely, distributively, and collaboratively participate in the design process in real-time while utilizing video, voice, chat, and intuitive build tools. One major area that is currently being supported is the design and evaluation of Command and Control (C2) spaces. VWs provide the infrastructure and support to develop customized tools to satisfy various evaluation criteria and metrics. In addition, VWs allow prototype C2 systems to be evaluated in the form of a Concept of Operation Exercise (COOPEX). In a virtual COOPEX, not only are the operators immersed into the physical space, but they are given full control of live real-world hardware and software systems. Both system effectiveness and operator performance are able be assessed from the virtual environment. These capabilities are currently being utilized by multiple USW programs changing the way the Navy approaches the challenge of meeting the war-fighters’ need. The Joint Exploratory Undersea Warfare Laboratory (JEUL) Distributed Simulation Environment (DSE) Supporting System Engineering Dr. Lynn Ewart, Naval Undersea Warfare Center (Division Newport), United States David Bellino/Frederick Pope, NUWC, USA Modeling and simulation (M&S) has been used for years for a broad spectrum of analyses: from high fidelity M&S for component design and testing to low fidelity M&S to support theater level analyses for operational requirements. This presentation will start with background on distributed simulations environments and then discuss the Joint Exploratory Undersea Laboratory (JEUL) distributed simulation environment (DSE). The JEUL DSE was developed to integrate across the fidelity range in support of system engineering. System engineering processes are used to provide input into scenario design from theater level analyses. Higher fidelity models are federated into the DSE as required to serve the purposes of a given simulation as defined through the Federation Development and Execution Process. The JEUL DSE provides an array of functionality from live-virtual-constructive simulations to a test bed for autonomy control software. It is also the first DSE to incorporate as a federate a virtual world (VW) simulation. The VW federate allows human-in-the-loop control of simulation entities in a command centre setting. Environment Variability and Granularity in Naval Warfare Simulation Dr Dominique FATTACCIOLI, DGA Naval Systems, France DGA Naval Systems is conducting advanced studies in support of technology assessment, naval warfare systems design and acquisition. Assessing warfare effectiveness and mastering global performance is carried out with advanced simulation systems. Aiming for better efficiency, reactivity and for completeness of the battle space description, unification of all legacy simulation tools has recently been accomplished in a new simulation software suite: ASTON. With its Model Driven Architecture ASTON provides an open, flexible and scalable simulation workspace. In order to account for the effect of the environment and assess its impact on performance, an innovative approach has been taken by considering the environment truly as an actor of the simulation. This approach will be presented, in which the environmental depiction can be called in simulation scenarios at different levels of granularity, allowing: (1) tactics adaptation to environment variability and (2) impact assessment of knowledge level of the environmental description on the warfare effectiveness. For illustration purpose, a particular focus will be paid to simulation scenarios based on passive sonar detection through submarine vs. submarine duels.
