Description
Reasoning with Situations
Knowledge
Base
E1
E4
Σ
• a multi-agent architecture developed for
automated information fusion and C2
tasks.
We rarely consider facts in isolation.
ATTITUDE uses events to partition
the knowledge base and capture
mental snapshots of the world over a
limited region & time.
E2
E3
• uses propositional attitudes as intuitive
programming constructs.
• supports reasoning with uncertainty.
We often wish to contemplate
situations which exceed any
particular event. Scenarios are
formed dynamically from events
using Boolean operators
E5
• supports reasoning with ‘situations’ for
high-level fusion.
• models organisational entities and
performed logistics planning for medevac
operations on HMAS Coonawarra in CoAX
2002 scenario.
Querying and inferencing
is contextual wrt events &
scenarios. Allows ‘what if’
reasoning with scenarios.
Logistics Planning
• HMAS Coonawarra agent requests medical
monitoring support and invokes mobile
agent infrastructure.

CC agent
• medical crisis triggers medevac planning.
• logistics agent queries HMAS Coonawarra
agent for available resources.
MAD Sensor feed
• HMAS Coonawarra agent queries CFMCC
for available helicopters & medical
facilities.
• logistics agent formulates medevac plan
using available resources and sends plan
to MCA for deconfliction and execution.
• casualties safely evacuated to USS Colin
Powell.

Briefing
agent
• embodied agents can give situation
reports, multimedia briefs, invoke
applications, or interact conversationally
with users.
• ‘natural language’ dialog builds trust
through interaction, and conveys situation
awareness to user through visual
explanation.
