3. 1. Introduction

4. Natural disasters are associated to chaotic situations in which information is
usually incomplete and imprecise, and this lack of information makes difficult
the process of making decisions and managing effectively catastrophes.
• Public awareness is an essential element of preparedness for saving lives and
livelihoods.
•Individuals and communities play important roles in managing risks from
natural hazards.

17. Mobile Client
• Developed with Mojax
Framework for Mobile Ajax

Creates J2ME applications

using web technologies
(HTML, CSS, JavaScript)
Mojax
• Synchronized with the platform
• Compatible in any terminal with Java
• Only data transmission (no
presentation)
• Works with/without connectivity

20. Expert System based on Rules
Developed with Jess (Sandia National Labs)

Resource planification and assignation in real time

Resources are assigned and freed based on rules

wich take into account:
disaster severity

3
number and severity of casualties

1
associated traffic

2
possibility of increasing…

21. Expert System based on Rules

22. Multiagent Platform
• Developed with Jadex: BDI Reasoning Engine (Belief-Desire-Intention)
• Four different agents for two different architectures (centralized vs
descentralized)
FIRE ENGINE POLICE CAR COORDINATOR
AMBULANCE
• Purpose: simulation (now) and more (to come) such as making-decission
support, coordination…

23. 5. Conclusions

24. Conclusions
Disasters2.0 has been shown as a web2.0 based platform which

enables sharing and managing disasters information generated by
users.
The platform provides a REST API which enables any client to

interact with it. As an example, a web client and a mobile client
have been developed.
Intelligent techniques can also leverage the REST API to interact

with the platform such as the Expert System or the Multiagent
Platform developed.
