Objective
Enable the student to use computational resources for the processing, analysis, quantification and simulation of physical and biological processes in agricultural systems. To present the principles and main techniques of process-based modeling of the growth and development of agricultural crops and to enable them to understand and develop numerical computational models. Basic concepts of dynamic simulation of agricultural systems and modeling methods including sensitivity analysis, parameter estimation, stochastic analysis and model evaluation. Application of models in the analysis of agricultural systems.

Content
1) Types of models: Statistical, empirical, deterministic, mechanistic models. Dynamic and static models. Macroscopic and microscopic models. Flow-charts used in the analysis of agricultural systems.
2) Modeling tools: conservation laws and principles; differential and integral equations, numerical simulation. Discrete and continuous modeling.
3) Stochastic process modeling concepts: distribution, covariance, random variables, correlated random variables. Uncertainty.
4) Evaluation and benchmarking of models. Model sensitivity to parameters. Comparison between simulations and real data. Comparison between models. Cross-validation.
5) Development of a model based on a process of interest related to an agricultural system and presentation of modeling results in the form of a seminar at the end of the semester.
