| contents | This article describes an improved set of solutions to the problems presented in the 2021 Syngenta Crop Challenge in Analytics \citep{Syngenta2021}. In particular, we use multiobjective optimization and predictive modeling methods to determine a corn planting schedule. The problem involves the following objectives: i. minimize the median and maximum absolute difference between weekly harvest quantity and the storage capacity, the number of nonzero harvest weeks, and the total amount of corn wasted. This is accomplished while respecting planting windows, expected harvest amounts, the growing degree units required to bring seeds to harvest, and historical weather data. We used a Long Short-Term Memory model to predict growing degree units for 2020 and 2021, based on historical data. Then, we used a genetic algorithm, and an extensive search of the tuning parameter space, to produce a Pareto front of solutions for three distinct optimization models related to the Challenge. We evaluate the quality of the Pareto fronts for each model, and use the results to choose a preferred model and final solution. We also provide comparisons between our final solutions, previous solutions submitted to the Challenge, and solutions from other groups. |
