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



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

Methods and ToolsMethods and ToolsAction selector agent structure:

Domain representation -> focused on organizational emergency structure, management resources and physical layout;

Preference System -> the agent goal is to choice 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.


Specification of EIDA ToolKit KernelSpecification of EIDA ToolKit Kernel Wp3Wp3


- 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

Implementation and Validation of Implementation and Validation of EIDA ToolKit KernelEIDA ToolKit Kernel
