Plan 1. Industrial Context 3. AMOMCASYS : Adaptable MOdeling Method for Complex Administrative SYStems 5. CIASCOTEWA : Cooperative Information Agent Systems for Cooperative Technological Watch 7. IMAS Design 9. First Results 11. Perspectives and Conclusion
1
Industrial and Social Context • Current Administrative systems : – from bureaucracy to a more process centred organisation [Schael]
AOIS 2003 - Chicago
“more holonic ” [Koestler 69]
order communications functional unity hierarchy relationships
objective communications process unity responsibility relationships

Application context Internet

-> technological watch department of a large company (SOLVAY S.A.) Information Agent Users of the technological watch department
-> have a coherence in a group of distributed users -> Use of Multi-Agent Systems

Proposition of AMOMCASYS • Comparison of several methods (MERISE, OMT, (UML), SADT, OSSAD, CISAD, MKSM) • Conclusion : No method fulfils all our needs => integration of pertinent parts of these methods • AMOMCASYS : Adaptable MOdeling Method for Complex Administrative SYStems
AOIS 2003 - Chicago
– Methodology: evolutionary approach, integrating the actors in the stages of analysis, modeling and specification – Organization: holonic organization, based on exchanges of documents – Representation : accessible models of data, dataflow, processing and a dynamic model – Co-operation : use of the dynamic model and of a simulator

CIASCOTEWA • Cooperative Information Agent System for COoperative TEchnological WAtch • Why? – Economical issue of technological watch – Allow a group to search information, without redundancies
• How?
AOIS 2003 - Chicago
– Dedicated an information multi-agent system to each actor of the technological watch department

CIASCOTEWA Design • Reuse of a methodology that we have built in HOMASCOW project
AOIS 2003 - Chicago
(Holonic Multi Agent System for helping COoperative Work)
– First, design individual competences of the different agents – Secondly, design of cooperative working of the CIASCOTEWA agents

Perspectives for Cooperation • Objective: identify groups of actors having same interests centres to encourage them to cooperate • Use of the Kohonen algorithm that regroups elements according to their distance from a null vector [Kohonen 91] • Definition of an interest distance from the keywords used in the requests
AOIS 2003 - Chicago

Conclusion • We use AMOMCASYS method to integrate an agents organization into a human organization – Future : • use of UML diagrams or A-UML in addition of AMOMCASYS
• Integration of users in the setup of the project is important
• Other project : proposition of a third part application from the CIASCOTEWA, with notion of security AOIS 2003 - Chicago
