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

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
