Installation

First clone the repository:

git clone https://github.com/akalikadien/shell-ai-hackaton-2023.git

Next, install or load conda and create a new environment from the environment.yml file:

conda env create -f environment.yml

Activate the environment:

conda activate shell-ai-hackaton

Data

1.initial_datasets/ contains the initial datasets that were supplied with the challenge

Biomass_History.csv: A time-series of biomass availability in the state of Gujarat from year 2010 to 2017. We have considered arable land as a map of 2418 equisized grid blocks (harvesting sites). For ease of use, we have flattened the map and provided location index, latitude, longitude, and year wise biomass availability for each harvesting site
Distance_Matrix.csv: The travel distance from source grid block to destination grid block, provided as a 2418 x 2418 matrix. Note that this is not a symmetric matrix due to U-turns, one-ways etc. that may result into different distances for ‘to’ and ‘fro’ journey between source and destination.
sample_submission.csv: Contains sample format for submission

2.additional_data/ contains data that we use to enrich the initial datasets for prediction

max_temp: gridded data from IMD regarding the max temperatures in Gujarat
min_temp: gridded data from IMD regarding min temperatures in Gujarat
rainfall: gridded data from IMD regarding rainfall in Gujarat. Final_Rain_data contains interpolated rainfall data for locations that did not have data. This is contained in the files Rain_Prediction{year}.csv
temperature predictions: contains interpolated data for locations that are missing in the gridded min_temp and max_temp from IMD. Currently the interpolation is based on the inverse weighted distance method.
pmgsy_facilities_gujarat.csv: gridded data on types of facilities in Gujarat

3.predictions/ contains final files that will be merged into a submission file

biomass_predictions.csv: predictions for biomass availability in 2018 and 2019

Code

For our final submissions there are 3 python files that are important, predictions via RF with the features from additional_data were done in a separate jupyter notebook.

place_storage_and_refineries_optimize_flow: contains code to place the depots and refineries using k-medoids, afterwards a genetic algorithm is used to optimize the flow of biomass and pellets, these flows are written to a csv file
place_storage_and_refineries_decision_based: same, but here we take a decision based approach to place the depots and refineries (assume all depots at max capacity and distribute from there)
process_all_data_for_submission: contains code to process all data and make a submission file
predict_biomass: contains code to do an ARIMA prediction on the biomass availability (this is not the prediction that we used for our final submission)
