Agenda

• Background
• Objectives
• CBD Project
• Project Overview
• Current Challenges
• Technical Approach

3
Background

• Current CGF systems will need more complex, new
  behaviors
• To support more complex training
• To support new equipment, tactics and
  organizational structures
• To support changing military missions and events
• Designing and implementing new CGF behaviors are
  expensive for current CGF systems

4
Project Overview

• A Research and Development Project
• Funded by Office of Naval Research (ONR)
• Our Objective Develop a case-based design (CBD)
  tool
• To help users to analyze and understand relevant,
  working behaviors solutions
• To help users understand how to modify and adapt
  existing behaviors to significantly reduce
  development time

Building New OneSAF Behaviors
Task and Behavior Description
KA/KE Engineer

• How do I implement each component of the
  specification?
• How is the data flow represented within the
  composites?
• Is there a more efficient way to encode this
  behavior?
• ..
