  1. Modeling Information Technology Needsin the Agriculture Domain Anna Perini, Angelo Susi {perini,susi}@irst.itc.it ITC - IRST, SRA Division Via Sommarive 18 - 38050 Povo, Trento SRA Division TROPOS Workshop 15-16.11.2001

  2. OUTLINE • The Integrated Production Problem in Agriculture • The Problem Domain analysis (Tropos ER modeling) • Analysis of the Needs • A system at use of … (Tropos LR modeling) SRA Division TROPOS Workshop 15-16.11.2001

  3. OUTLINE • The Integrated Production Problem in Agriculture • The Problem Domain analysis (Tropos ER modeling) • Analysis of the Needs • A system at use of … (Tropos LR modeling) SRA Division TROPOS Workshop 15-16.11.2001

  4. Integrated Production in Agriculturetwo principles relatives to defense actions • a tolerance threshold under which plant disease damages can be economically accepted • a classification of chemicals and techniques, with respect to their impact on the environment, including growers and consumers, authorized by International Organization for Biological Control and by local government SRA Division TROPOS Workshop 15-16.11.2001 4

  5. Integrated Production:an example • Venturia Inæqualis (a species of fungus, Ticchiolatura in Italian) an apples pest; on July 2% of infected fruit is considered an acceptable threshold • the problem is to “Find the conditions and the actions to rise an amount of infected fruits less then 2%, using authorized techniques” SRA Division TROPOS Workshop 15-16.11.2001

  6. Integrated Production:information and skills • Historical data • Monitoring of current orchard status • Weather forecast • Information about chemicals • Synthesis of experiences from other advisors SRA Division TROPOS Workshop 15-16.11.2001

  7. Integrated Production:two dimensions • Technical dimension: orchards management, pest models development and use … • Organizational dimension: coordination between Institutions, Producer Organizations, Advisors …each one having its own goal …. contributing to the global objective of making IP practices to become used … SRA Division TROPOS Workshop 15-16.11.2001

  8. OUTLINE • The Integrated Production Problem in Agriculture • The Problem Domain analysis (Tropos ER modeling) • Analysis of the Needs • A system at use of … (Tropos LR modeling) SRA Division TROPOS Workshop 15-16.11.2001

  9. Problem domain analysis • Interviews to producers technicians and domain experts, acquisition of domain documentation • Analysis of the actors roles and dependencies • Description of actors, goals and dependencies into a ER model according to Tropos methodology: • Actor dependencies • goal-analysis • plan-analysis SRA Division TROPOS Workshop 15-16.11.2001

  10. IP organizational settingER goal diagram SRA Division TROPOS Workshop 15-16.11.2001

  11. Goal-analysisGive assistance to producers SRA Division TROPOS Workshop 15-16.11.2001

  12. The Advisor – ER Goal DiagramVenturia inæqualis SRA Division TROPOS Workshop 15-16.11.2001

  13. OUTLINE • The Integrated Production Problem in Agriculture • The Problem Domain analysis (Tropos ER modeling) • Analysis of the Needs • A system at use of … (Tropos LR modeling) SRA Division TROPOS Workshop 15-16.11.2001

  14. Integrated Production Needs analysis • For the Advisors decision support system: • model for pest management • Improve the quality of communication between advisors • For the biology research institutes: • new techniques for the developing of pests models SRA Division TROPOS Workshop 15-16.11.2001

  15. OUTLINE • The Integrated Production Problem in Agriculture • The Problem Domain analysis (Tropos ER modeling) • Analysis of the Needs • A system at use of … (Tropos LR modeling) SRA Division TROPOS Workshop 15-16.11.2001

  16. The Advisor point of viewER Goal Diagram: Venturia Inæqualis SRA Division TROPOS Workshop 15-16.11.2001

  17. Late Requirement Goal Diagram SRA Division TROPOS Workshop 15-16.11.2001

  18. The dssPICO actor - LR Goal Diagram SRA Division TROPOS Workshop 15-16.11.2001

  19. Conclusion & Future work • What’s next (from the Pico project perspective): • architectural design, detailed design and development … • Lessons learned: • An organization model - a “tool” which supports the communication between the analysts and the users • Issues for the research: • Modeling actors coordination through actor dependencies
