A D ECISION S UPPORT S YSTEM FOR OPTIMIZATION OF AGRONOMICAL INPUTS Paper prepared for presentation at the 20 th ICABR Conference ““T RANSFORMING THE B IOECONOMY : B EHAVIOR, I NNOVATION AND S CIENCE ”” Ravello (Italy): June 26 - 29, 2016 F RANCESCO C ONTÒ, G IANLUIGI D E P ASCALE, C LAUDIO Z AZA, N ICOLA F ACCILONGO Department of Economics, University of Foggia, Italy Lecturer: G IANLUIGI D E P ASCALE

2. AGENDA OF THE PRESENTATION  KEYWORDS  SUBJECT AND AIMS  THE NEW COMMON AGRICULTURAL POLICY  SHORT METHODOLOGY NOTE  EXPECTED VALUES  REFERENCES

3. KEYWORDS  D ECISION S UPPORT S YSTEM  A GRONOMICAL INPUT  C OBB -D OUGLAS

4. SUBJECT AND AIMS (Fountas S. et al., 2016) FARMS MATHEMATICAL MODEL DECISIONAL PHASE OPERATIVE PHASE

5. THE NEW COMMON AGRICULTURAL POLICY (Capitiano F. et al., 2016)  Qualitative Agriculture:  Healthy Food  Low environmental impact  Innovative Agriculture

6. SHORT METHODOLOGY NOTE COBB-DOUGLAS LINEAR PRODUCTION FUNCTION ( G OLDBERGER S., A. 1968 ) A = parameter K = capital L = labour α = weight of capital β = weight of labour

7. SHORT METHODOLOGY NOTE - Variables F = quantity of fertilizers to use; P = quantity of pesticides to use; HR = Humidity relative; e v = partial pressure of the water vapor present at a given temperature; e s = partial pressure of the water present at saturation for given temperature; I = impoverishment of the land; A = parameter of external factors that simplify access to the markets; α = weight of fertilizers used; β = weight of pesticides used.

9. EXPECTED VALUES  M AKING THE ADOPTION OF CHEAP FASTER DECISIONS  R EDUCING A GRIGULTURAL I NPUT W ASTE  R EDUCING THE E NVIRONMENTAL I MPACTS How do variables interact among them?
