Calfee and published by . This book was released on 2003-03-01 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The AEGIS Cruiser Air-Defense Simulation is a program that models the operations of a Combat Information Center (CIC) team performing the ADC duties in a battle group using Multi-Agent System (MAS) technology implemented in the Java programing language. Set in the Arabian Gulf region, the simulation is a top-view, dynamic, graphics-driven software implementation that provides a picture of the CIC team grappling with a challenging, complex problem. Conceived primarily as a system to assist ships, waterfront training teams, and battle group staffs in ADC training and doctrine formulation, the simulation was designed to gain insight and understanding into the numerous factors (skills, experience, fatigue, aircraft numbers, weather, etc.) that influence the performance of the overall CIC team and watchstanders. The program explores the team's performance under abnormal or high intensity/stress situations by simulating their mental processes, decision-making aspects, communications patterns, and cognitive attributes. Everything in the scenario is logged, which allows for the reconstruction of interesting events (i.e. watchstander mistakes, chain-of-error analysis) for use in post-scenario training as well as the creation of new, more focused themes for actual CIC team scenarios. The simulation also tracks various watchstander and CIC team performance metrics for review by the user.

This book was released on 2008-07-04 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's military missions have shifted away from fighting nation states using conventional weapons toward combating insurgents and terrorist networks in a battlespace in which the attitudes and behaviors of civilian noncombatants may be the primary effects of military actions. To support these new missions, the military services are increasingly interested in using models of the behavior of humans, as individuals and in groups of various kinds and sizes. Behavioral Modeling and Simulation reviews relevant individual, organizational, and societal (IOS) modeling research programs, evaluates the strengths and weaknesses of the programs and their methodologies, determines which have the greatest potential for military use, and provides guidance for the design of a research program to effectively foster the development of IOS models useful to the military. This book will be of interest to model developers, operational military users of the models and their managers, and government personnel making funding decisions regarding model development.

Download or read book Autonomous Agent Based Simulation of Anti Submarine Warfare Operations with the Goal of Protecting a High Value Unit written by Fahrettin Akbori and published by . This book was released on 2004-03-01 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Anti-Submarine Warfare screen design simulation is a program that provides a model for operations in anti-submarine warfare (ASW). The purpose of the program is to aid ASW commanders, allowing them to configure an ASW screen, including the sonar policy, convoy speed, and the number of ships, to gain insight into how these and other factors beyond their control, such as water conditions, impact ASW effectiveness. It is also designed to be used as a training tool for ASW officers. The program is implemented in Java programming language, using the Multi Agent System (MAS) technique. The simulation interface is a Horizontal Display Center (HDC) which is very similar to a MEKQ2OO class Frigate Combat Information Center's (CIC) HDC. The program uses Extensible Markup Language (XML) files for reading data for program scenarios; parameters are initialized before each run time begins. The simulation also provides all the output data at the end of run time for analysis purposes. The program user's goal, and the purpose of the program, is to decrease the number of successful attacks against surface vessels by changing the configuration parameters of the ASW screen, to reflect sonar policy, convoy speed or number of ships in the simulation. Ongoing use of the program can provide data needed to anticipate required operational needs in future ASW situations.

Download or read book Artificial War written by Andrew Ilachinski and published by World Scientific. This book was released on 2004 with total page 782 pages. Available in PDF, EPUB and Kindle. Book excerpt: Military conflicts, particularly land combat, possess the characteristics of complex adaptive systems: combat forces are composed of a large number of nonlinearly interacting parts and are organized in a dynamic command-and-control network; local action, which often appears disordered, self-organizes into long-range order; military conflicts, by their nature, proceed far from equilibrium; military forces adapt to a changing combat environment; and there is no master ?voice? that dictates the actions of every soldier (i.e., battlefield action is decentralized). Nonetheless, most modern ?state of the art? military simulations ignore the self-organizing properties of combat.This book summarizes the results of a multiyear research effort aimed at exploring the applicability of complex adaptive systems theory to the study of warfare, and introduces a sophisticated multiagent-based simulation of combat called EINSTein. EINSTein, whose bottom-up, generative approach to modeling combat stands in stark contrast to the top-down or reductionist philosophy that still underlies most conventional military models, is designed to illustrate how many aspects of land combat may be understood as self-organized, emergent phenomena. Used worldwide by the military operations research community, EINSTein has pioneered the simulation of combat on a small to medium scale by using autonomous agents to model individual behaviors and personalities rather than hardware.
Download or read book Assessing Aegis Program Transition to an Open architecture Model written by Paul DeLuca and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aegis is a highly integrated U.S. Navy combat system with anti-air warfare, ballistic missile defense, surface, subsurface, and strike roles that is currently operating on 84 ships. To reduce the costs of maintaining the system, and to take advantage of rapidly evolving commercial computing technology, the Navy is moving Aegis toward open-architecture software, a common source code library, and commercial, off-the-shelf processors. As it moves forward in implementing its integrated weapon system (IWS) model for the development, integration, and testing of upgrades to the Aegis weapon system, the Navy must consider the impact of this plan on Aegis facilities, personnel, and timelines. Of particular concern are the effects of new modernization and fielding rates on the technical infrastructure of the Aegis fleet. This report examines the potential benefits of the IWS model and the challenges associated with the transition from the Navy's legacy model for Aegis acquisition and development. It examines the pace of upgrades to both hardware and software and the speed with which they spread throughout the fleet. Finally, it proposes an upgrade schedule that offsets software (advanced capability builds) and hardware (technology insertions) to maximize the Navy's benefit from commercial industry's technology replacement cycle and ensure value for fixed development and testing budgets.
Download or read book Developing Realistic Cooperative Behaviors for Autonomous Agents in Air Combat Simulation written by and published by . This book was released on 1993 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigated, developed and implemented cooperative decision-making behaviors in an air combat simulation by using a knowledge-based system. Knowledge-based systems were well suited for this task because of built- in features such as inference engines and rule-based constructs. This thesis addresses the specific problem of generating autonomous forces for inclusion in the Advanced Research Projects Agency Distributed Interactive Simulation program. Existing autonomous forces implementations lacked flexibility, realistic behaviors, real-time planning and other features. The simulation system in this thesis addresses the problem of realistic behavior by modeling pilot decision processes rather than aircraft platforms. The system is based on phased control of a blackboard architecture. Modular knowledge bases partition rules to process decision data. Cooperative behaviors are based on a leader- follower relationship. Agents share the workload in assessing threats. Leaders make the initial decision, but followers react independently if necessary. The simulator described in this thesis provides an architecture and design for modeling combat pilot decision processes. The system was developed using the C Language Integrated Production System Object Oriented Language.
Download or read book Autonomous Agent Based Simulation of a Model Simulating the Human Air Threat Assessment Process written by Baris E. Ozkan and published by . This book was released on 2004-03-01 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Air Defense Laboratory (ADL) Simulation is a software program that models the way an air-defense officer thinks in the threat assessment process. The model uses multi-agent system (MAS) technology and is implemented in Java programming language. This research is a portion of Red Intent Project whose goal is to ultimately implement a model to predict the intent of any given track in the environment. For any air track in the simulation, two sets of agents are created, one for controlling track actions and one for predicting its identity and intent based on information received from track, the geopolitical situation and intelligence. The simulation is also capable of identifying coordinated actions between air tracks. We used three kinds of aircraft behavior in the simulation: civilian, friendly and enemy. Predictor agents are constructed in a layered structure and use "conceptual blending" in their decision-making processes using mental spaces and integration networks. Mental spaces are connected to each other via connectors and connecters trigger tickets. Connectors and Tickets were implemented using the Connector-based Multi Agent System (CMAS) library. This simulation is one of the first applications to use cognitive blending theory for a military application. We demonstrated that agents can create an "integration network" composed of mental spaces" and retrieve any mental space data inside the network immediately without traversing the entire network by using the CMAS library. The results of the tests of the simulation showed that the ADL Simulation can be used as assistant to human air- defense personnel to increase accuracy and decrease reaction time in naval air- threat assessment.
Download or read book Users Manual for Naval Air Defense Simulation NADS Special Programs Revision written by TRW DEFENSE SYSTEMS GROUP MCLEAN VA WATERWHEEL PROGRAM OFFICE. and published by . This book was released on 1986 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Naval Defense Simulation (NADS) is a large scale simulation of the defenses of a Carrier Battle Group, CVBG, under attack by antiship missiles launched from ships, submarines, and bombers. NADS treats with considerable detail the airborne assets of the attacking Red force and the AAW assets of the Blue defending force. A prominent feature of NADS is its simulation of the Carrier Battle Group's acquisition of tactical information by its own resources, supplemented by external surveillance information. The battle group command center maintains a continually updated Blue Perception of the tactical situation. All of the tactical decisions are based on that perceived picture invoked by data that are often deficient in accuracy, completeness, and timeliness. The NADS model is organized to fit the conventional defense-in-depth zones; the outer air battle; the surface-to-air, SAM, area defense; and the terminal defenses. It should be noted that a battle force without aircraft carriers is compatible with NADS, as any element of the CVBG may be omitted. Also the aircraft capability of a land airfield can be simulated with the appropriate inputs. Keywords: Computer files; FORTRAN; Computer program documentation.
Download or read book Modeling and Simulation of Fleet Air Defense Systems Using EADSIM written by Neil Robert Bourassa and published by . This book was released on 1993 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this thesis is to develop a capability to simulate naval anti-air warfare (AAW) systems at the Naval Postgraduate School (NPS). Students in many curricula at NPS can use such a model in thesis research or course work related to air defense. Examples of courses in the Department of Aeronautics and Astronautics in which there is a use for AAW simulation are AE3705 Air Defense Lethality and AE3251 Aircraft Combat Survivability . The Extended Air Defense Simulation (EADSIM) was selected as the model to acquire and install on the Silicon Graphics computer workstations of the Computer Center Visualization Laboratory. EADSIM was developed by Teledyne Brown Engineering for the U.S. Army Space and Strategic Defense Command and is a powerful analysis tool that can model many aspects of air warfare. The author has used EADSIM to develop AAW and Strike Warfare scenarios for use in AE3705 and AE3251. These scenarios required the creation and modification of platforms within the graphical user interface to simulate naval units. These scenarios can be run and displayed as animated playback files for analysis. In addition, the EADSIM weapon performance model was studied. The default values for weapon systems probability of kill (Pk) were modified, and the results were examined to determine the overall effect of Pk within a simulation.
Download or read book Autonomous Agent Interactions in a Real time Simulation System written by Gary Michael McAndrews and published by . This book was released on 1994 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major problem addressed by this research is the design and implementation of a command and control architecture to add company-level missions to an existing real-time combat-simulation system. The US Army is using Modular Semi-Autonomous Forces (ModSAF) to conduct research in simulation training. ModSAF only provides platoon and vehicle missions. Adding company level missions to ModSAF will allow a single operator to effectively control a greater number of forces and retain realistic behaviors. The approach taken was to utilize ModSAF's finite-state machine architecture, and NPSNET -- a three dimensional combat-simulation system, to develop, test, and implement a company-level combat simulation mission. Simplistic terrain reasoning algorithms and a command and control finite state machine architecture were added to the ModSAF system. The result is a prototype company-level mission Occupy an Assembly Area, ' providing a successful proof-of- concept implementation of company level mission development using ModSAF's current finite state machine architecture. This research provides the groundwork for further development of company-level combat simulations in ModSAF.

Book excerpt: The report formulates an improved general methodological approach for the development of computer-assisted evaluation of trainee performance in the computer-based simulation environment, and in other training environments where computer capacity is available to record and process trainee response data. The report is part of an ongoing development effort for the Tactical Advanced Combat Direction and Electronic Warfare (TACDEW) system at the Fleet Anti-Air Warfare Training Center (FAAWTRACENSD). TACDEW is a computerized simulation system for individual team and multi-team training for Combat Information Center, Command and Decision, Air Intercept Control, Electronic Warfare, Carrier Controlled Approach, and Air Tactical Data System. Both conventional and Navy Tactical Data Systems (NTDS) are represented. Six basic methodological steps are proposed: Identify system entities; identify major types of operations; and processing; determine situational variables and their recording and processing; analyze and interpret performance data. Follow-on studies are discussed for multi-team (CIC) anti-air warfare, single CIC anti-air warfare, carrier controlled approach, air intercept control, surface maneuvers (radar navigation), and electronic warfare.

Download or read book Agent Based Simulation of Unmanned Surface Vehicles A Force in the Fleet written by and published by . This book was released on 2004 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Navy is considering the use of unmanned surface vehicles (USVs) to reduce risk to personnel in maritime interdiction operations, and to conduct intelligence, surveillance and reconnaissance (TSR) and force protection (FP) missions. In this thesis, alternative configurations of the prototype and operational uses of the USV are explored using agent-based simulation for three scenarios. An efficient experiment design alters settings of ten factors for the two ISR scenarios and 11 factors for the FP scenario. Some factors varied in the experiment are uncontrollable during operations, such as the total number of contacts, threat density, their maneuvering characteristics, and the sea state. The USV sensor range and endurance are also considered as well as factors set by the decision-maker for a particular mission: namely, USV speed and numbers to deploy. The results provide several operational and tactical insights with implications for patrolling and combat radius, and form the basis for a recommendation to use the USV in an active role in maritime missions. The results also support the guidance on the benefits of improving USV sensing and endurance capabilities, and find that simply increasing USV numbers is not necessary for attaining high mission performance.
