2. Deliverables and impact Holonic modeling framework development Prototype simulation model development Benefits to the material handling industry- designers, manufacturers and users

3. Existing frameworks Hierarchical framework Heterarchical framework Cooperative systems framework Distributed systems framework Opportunistic systems framework

4. Basis for new framework Individual System Cell

5. Various levels of interactions Between individual agents Between agent and cell controller Between agent and system controller Between cell controllers Between cell and system controller

6. Basis for new framework System Cell Individual M H P

7. Modeling framework ‘Holonic’ modeling framework –Holons make autonomous decisions –Higher level controllers –Guidelines and system wide constraints Material handling systems control

8. Hybrid Control Strategy

9. Intelligent Agents Intelligent agents representing –Entities and resources –Functioning cooperatively –Accomplishing individual, cell-wide and system-wide goals

10. Highlights of new framework Considers interactions among entities operating at various levels Explicitly captures interactions of MHS with manufacturing system Uses optimization, learning & knowledge based approaches in problem solving Has built-in features for optimal system performance, stability and convergence

11. Industry Collaboration Efforts underway to: –apply modeling framework to industrial problem –compare performance of the new methodology to existing ones –develop novel control system for MHSs
