Definition and goals of SimCIP

SimCIP - Simulation for Critical Infrastructure Protection SimCIP is an agent based simulation

environment, aimed at modelling and simulating systems of Critical Infrastructures (CI).

The purpose of SimCIP is to help understand the dependencies within complex infrastructure.

SimCIP should also serve as test for Middleware Improved Technology (MIT).

IRRIIS

Preliminaries: basics of the network model

The network model for SimCIP is based on the ISE-Model, the Leontief input-output model adapted to

critical infrastructures and a multi-agent concept in which CI-

components are agents and CI-Systems are systems of agents.

IRRIIS

The ISE-Model

Focus on services,

iterative processing and

Extension to other layers

Dependencies within

and between layers

Consists of three layers:

implementation,

services and effects

internal effect factors internal effect factors

global effect factors

Submodel 1 (e.g. telecommunication) Submodel 2 (e.g. electric power)

IRRIIS

Leontief model of infrastructures

Adapt Leontief economic model to model critical

infrastructures: System of interconnected and interdependent

services. Inputs to a service is the inoperability of services

it depends on. Output of a service is its own inoperability that

serves as input for other services.

IRRIIS

SimCIP state of the art

• Offers a GUI based interface for developing CI-models and simulation.

• Modelling and simulating occur in one single application.

• Produces simple flat files that can be evaluated with other software e.g. MS-Excel.

• Can be used in different modes: online, batch and mixed mode.

IRRIIS

SimCIP open questions and future work

• Further development and refinement of the CI-model

• Data models and definitions

• Tools for analysis

• Graphical User Interface (GUI)

• Test-bed for MIT

• External CI-Simulators
