Integrated Production in Agriculture two 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

Integrated Production: an example
SRA Division TROPOS Workshop 15-16.11.2001
• 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”
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

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 …

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

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

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
