A Water Supply Optimization Problem for Plant Growth Based on GreenLab Model

Authors: Lin Wu ; Philippe De Reffye ; Bao-Gang Hu ; François-Xavier Le Dimet ; Paul-Henry Cournède

GreenLab is a structural-functional model for plant growth based on multidisciplinary knowledge. Its mathematical formalism allows dynamic simulation of plant growth and model analysis. A simplified soil water balance equation is introduced to illustrate the interactions and feedbacks between the plant functioning and water resources. A water supply optimization problem is then described and solved: the sunflower fruit weight is optimized with respect to different water supply strategies in a theoretical case. Intuitive searching method and genetic algorithms are used to solve this mixed integer nonlinear problem. The optimization results are analyzed and reveal possible agronomic applications.
