from the Conventional Software(03E-SIW-037)

Abstract
  • This paper presents a study to decompose a
    conventional wargame system into a set of
    federates that constitute an analytical wargame
    federation.
  • A prototype of an anti-missile vessel analytical
    federation was built and tested
  • Modular design that can easily adopt and evolve
    the analytical model
  • Replace or fine-tune the assessment model easily

Contents
  • Motivations
  • The Conventional Wargame system
  • The Analytical Federation
  • The Design Issues
  • The Implementation and Result
  • Conclusions

4
Motivations
  • The conventional analytical wargame system is a
    sequential flow of simulation.
  • Hypothetic initial conditions must be given.
  • Executed in a faster-than-real-time fashion.
  • Once executed, it will not stop until a specific
    condition is met, such as no. of rounds.
  • Drawbacks
  • The initial conditions must be realistic enough.
  • It is not perceivable to the user before the
    simulation is completed.

5
Course of Action (COA) Analysis
  • Facilitate the Course of Action (COA) analysis by
    combining the fast-than-real-time simulation with
    the real-time simulation.

6
Goals
  • Study the possibility of applying HLA to a pure
    analytical wargame system
  • Study the effort of upgrading the existing
    wargame system into an HLA-compatible system.
  • Research the possibility of increase the
    performance of the analysis
  • Increase the degree of the users intervention to
    research the enhancement of the analytical
    accuracy

7
Synchronization Issue
  • The key is to coordinate the time advancement
    within the federation
  • The time scales are different between the
    analytical federate and the real-time federate
  • Coordinate the event-oriented federate with the
    time-stepped one.
  • The HLA Time Management service provides the
    required capability
  • Time regulating / time constrained

The Conventional Analytical Wargame System

The Scenario
  • The Red party is the attacker that controls the
    cruise missiles trajectory
  • The Blue party is the defender to detect and
    intercept the missiles attack
  • A Monte Carlo model is implemented to perform the
    measure-of-effectiveness(MOE) assessment

10
The Simulation Flow
11
Simulation Stages
  • Attack
  • The cruise missile is launched
  • Engagement
  • The fire control radar is detected and locked
  • Interception is initiated
  • Assessment
  • Assess whether the interception is successful
  • If penetrated, then detect the result of the
    assault

12
The Federates
  • Decompose the conventional analytical system into
    three federates
  • Assessment federate Perform the Measure of
    Effective(MOE) statistical evaluation
  • Red federate Compute the cruise missiles
    trajectory
  • Blue federate Initiate the interception attempt
  • An additional federate for visual perception
  • 3D federateData Logger 3D stealth

The 3D (Stealth) Federate
  • Preview the ongoing analytical simulation
  • The stealth
  • Review the analysis
  • The logger
  • Using the commercial VR software

17
Time Management(1)
  • The red, blue, and assessment federates are
    coordinated by setting them to both
    time-regulating and time-constrained
  • They are executed in faster-than-real-time
  • They are executed at their own paces
  • They all send and receive messages in TSO
  • The simulating speed is dominated by the slowest
    regulating federate

18
Time Management(2)
  • The 3D federate is set to time-constrained
  • It is the slowest federate among the federation
  • It provides visual perception during the
    simulation
  • It should be constrained by the
    faster-than-real-time simulation

19
Synchronization Phases(1)
  • Since the analytical wargame system is required
    to be executed in multiple rounds, three
    synchronization points are set to divide the
    federation execution into three phases
  • The initiative phase
  • The primary phase
  • The simulation phase

20
Synchronization Phases(2)
  • Initiative phase
  • Use HLA services to perform necessary object/
    interaction declaration and time management
  • Primary phase
  • Save the initial values of all declared
    attributes and interactions
  • Simulation phase
  • Restore the saved values before performing the
    simulation for each round

22
The Final Amendment
  • The 3D federate produces a jiggling perception
    effect due to the scale discrepancy
  • The existing wargame system employed the
    resolution of 1300 and one time unit for each
    time step
  • The federation is amended by setting 0.1 time
    unit for each time step
  • The interpolation can be also used to reduce the
    jiggling effect, however, with some side effect.

Conclusions
  • This paper presents the work of upgrading an
    existing wargame system into an HLA-based
    analytical federation
  • Proof of concept
  • Modularize the assessment model
  • Possibility of conducting a courses-of-action
    evaluation
  • Experience of integrating a 3D federate into the
    analytical federation
