Automated Service Integration for Crisis Management Agencies create plans of action for disaster scenarios Often require interaction with other agencies or

centers Goals:

Locate and coordinate with personnel: Having necessary skills Able to meet plan constraints

Adapt to changing plans Assist personnel during execution

Approach: Plans represented as workflows Workflows encode tasks, the relationships among them For better integration, workflows also include:

Pre- and post- conditions, causal links, in/out params, exception handling, conditional branches, temporal constraints, resource usage, significance

5

Workflow Properties Workflow Correctness: A workflow is

correct if and only if it has no conflicting temporal or resource constraints.

Workflow Completeness: A complete workflow is a workflow that specifies all tasks needed to achieve its goals and preconditions.

Workflow Compatibility: A workflow is compatible with another if none of its tasks conflicts with any of the other’s (and vice versa).

Example of an emergency workflow

Select Ambulance Go-to Location

Acquire Victim

Go-to Hospital

Contact Police

Secure Location

Escort

Resource usage indicates: Required personnel skills Required equipment

Arrows show temporal constraints Relative or absolute max durations

How to Coordinate?

An Intelligent Personal Assistant (iPA): Used by all emergency personnel Mobile platform (PDA, cell phone) Data stream sources Gathers and presents useful information Uses context such as day, time, location, and

current activity Includes a profile of user behavior,

preferences, and capabilities Can be entered explicitly or learned over time

Slide inspired from [7] 8

Discovery using Broadcast

Agency broadcasts electronically its plan of action as workflow

Workflows received by available personnel through iPAs

If an iPA determines its user can contribute: Notifies user and asks for decision Relays decision to agency Receives confirmation or rejection from agency

Discovery and Integration

Coordination, Monitoring and Execution The centers can coordinate with the individuals

executing the tasks in their workflows via their iPAs. If iPA or its user determines changes to the current

workflow are necessary, the iPA can help by providing alternatives that still satisfy all requirements.

iPA provide an interface to information sources and fellow emergency personnel.

Queries to various sensor networks can be initiated through an iPA.

The greatest advantages of using an iPA for such applications are its own “initiative” and context awareness.

Combined with physical sensors (like a heart monitor), the iPA can also automatically “sense” when the firefighter needs medical assistance and contact someone nearby.

Conclusions

Presented a workflow representation of action plans for crisis management.

This scheme can be adapted to establish Virtual Organizations

Established the importance of global broadcast and mobile Intelligent Personal Assistants (iPAs)
