ADELFE [2000 ]

A toolkit to develop software with emergent functionalities

ADELFE Provides• Process • Notation • Tools

3

ADELFE Overview

Main characteristics:● Specific agent-based methodology

Exploiting the AMAS Theory → cooperation Open systems, adaptive to changes in the environment

● For engineers aware of MAS● Apply MDE principles

Principles● Based on RUP and standard notations (UML , AUML)● Top down approach:

- analysis phase - identification of agents● Bottom up approach:

- design phase – agent design

4

SPEM general characteristics● Provide a standard for method description, management,

interchange, enactment, etc.● Provide notations and concepts for method content and

process description● Promote and develop method use and re-usability

SPEM 2.0 new capabilities● Clear concerns separation

- Method content (reusable methodological brick)- Process definition (a particular use of these bricks)

● Re-usability- Method, process plug-in- Process pattern application- Process components

SPEM (v1.1/2.0) Software Process Engineering Metamodel

ADELFE SPEM 2.0 Applied Notations

Process definition SPEM 2.0 notations:

● Work product use

● Role use

● Task use

● Process performer (links Role use to Task use)

● Phase: activity special kind (From SPEM2.0 base plug-in)

SPEM 2.0 Analysis

Software design process● Semi-formal description● Verification, enactment (BPEL)● CASE tools● Design process orchestration

AOSE● Interoperability for agent oriented method contents and processes● Common frame, language to define agent method● Ease the definition of Methodological Fragments

- Reusable Method library and plugin- Reusable Process components

ADELFE● Facilitate method adjustment (automatic tools) ● Standard for publication, documentation, etc.● Support for end-users, web pages, orchestration etc.

19

ADELFE: Key Steps Environment characterisation

● Entities determination (active/passive)● Dynamic, static, accessible, continuous, etc.

Definition of non cooperative situations (NCS)● Between the system and its environment

NCS: kind of exceptions at the agent interaction level Verify the AMAS adequacy Agent Identification Agent Design

● UML models with stereotypes (ADELFE profile) ● Guide to define local rules for agent behaviour

Cooperative attitude

20

ADELFE: Perspective

Analysis and Design phases● Definition of DSML (AMAS-ML)

- Specific concepts with specific notations

Add an Implementation phase● MDE approach

- Model transformations chain- Code generation- Reverse Engineering

● Living Design during the implementation phase- Simulation as a design tool- Simulation for evaluation
