1 EIDA Project ( Proposal ) Emergency Intelligent Decision Assistant: Toolkit for Coordinated Emergency Management Research and Technical Background by C.Balducelli S.Bologna and A.M.Gadomski ENEA, July 1995

2 EIDA - Project (proposal( proposal) amg Summary Project Goals Project Methodologies and Tools Project Realization

3 EIDA Project amg Project Goals : Development of a domain-oriented toolkit and its validation for a class of Emergency Management active Decision Support Systems. Toolkit : 1) Domain problem conceptualization tools 2) Modeling tools 3) Methodology, methods and techniques 4) Software design tools 5) Software modules

4 EIDA Project active Decision Support Systems Goal-driven decisional support which is based on: user role-model domain model M-M cooperation model

5 EIDA Project Project Methodology and Tools Basic paradigmes: Top-down Object-based Goal-oriented Approach Basic conceptual couple: Environment interaction Intelligent Agent

6 EIDA Project Top-down and Object-based based : Top-down Object-based Structural decomposition of concepts Representation of concepts in term of objects and relations

7 EIDA Project Goal-oriented oriented : E-M goal (losses, risk, intervention,..), search search Domain( losses generation events, risk objects,..) search Toxic substances support of risk model search Maps (...)

8 EIDA Project Project main phases 1 - User Requirement specification 2 - Modeling 3 - Tools prototyping and verification 4 - Demos (user oriented applications) validation

9 EIDA Project 1 Generic Emergency Management Scenario N-th Decompositon level: Model 1 Model 2 Model 3 Model n Sub-Model 1 Sub-Model Sub-Model m integration Architecture of an ideal emergency manager selection 3 Prototype 1 Prototype 2... Prototype m 4 Verification User oriented demos modification Validation integration Architectur e of EIDA kernel modification

10 Formalization of the Applicative Domain Wp1 Summary - Domain of EM Activity - EM Activities and Tasks - EM operators organizational structure

11 Formalization of the Applicative Domain Wp1 Methods and Tools - Domain of EM Activity -> Reusing Muster Model - EM Activities and Tasks -> Use Task Analysis - Agents organizational structure -> ISEM Model

12 Definition of Models and System Requirements Wp2 Summary - Definition of a Common Terminology - Single Agent Model - Decisional Model Based on Agents Cooperation

13 Definition of Models and System Requirements Wp2 Methods and Tools Single Agent Model : Physical Domain of Activity AD P Abstract - Domain; a representation of Physical Domain of Activity Agent Preference System Data acquisition New Information AD Actions Decisions Goals K Agent Knowledge System P K

14 Definition of Models and System Requirements Wp2 Methods and Tools -> GEMS top-activities loop Domain models Emergency org. models What-if simul. Role-preferences Detecting/ monitoring Information acquisition: with/without request Diagnostics Previsions Decision- Making Cause searching Consequence searching Action / task choice Comunication Agent Diagnostic Agent Evaluator Agent Action Selector Agent

15 Definition of Models and System Requirements Wp2 Methods and Tools Diagnostic agent structure: Domain representation -> focused on the Causal Trees of the Emergency Events and Risk Objects Preference System -> the agent goal is to send to the evaluator agent more and more precise informations about event causes and event characterization Knowledge System -> has the task to execute Cause Searching Process. It could be based on Case Based Reasoning approach

16 Definition of Models and System Methods and Tools Requirements Wp2 Evaluator agent structure: Domain representation -> focused on Causal Trees of the Emergency Events and Risk Objects Preference System -> the agent goal is to refine evaluations performing a Consequence Searching Process Knowledge System -> is supported by Numerical Simulators and/or executes a qualitative Case Based Reasoning

17 Definition of Models and System Requirements Wp2 Emergency propagation map primary event cause searching model Domain model registrated event consequence searching model Domain model -risk

18 Definition of Models and System Requirements Wp2 Methods and Tools Action selector agent structure: Domain representation -> focused on organizational emergency structure, management resources and physical layout; Preference System -> the agent goal is to choise the best recovery actions and procedures on the basis of evaluation results; Knowledge System -> is composed by an action selector and an action executor. The action selector could be supported by a a Rule Based processing.

19 Specification of EIDA ToolKit Kernel Wp3 Methods and Tools - Choose of adeguate final software environment. - Software functional Specification and Testing (for the different agents) using a Case Tool - Design a Protocol for Data exchange between the agents - Design the Users Interface architecture

20 Implementation and Validation of Methods and Tools EIDA ToolKit Kernel Wp4 -Wp5 - Incremental implementation of the EIDA software Agents - Verification and Validation of the produced Kernel modules respect at least two different Users oriented prototypes. - Generalization of the produced ToolKit to support its utilization in other application of the same class
