OptBio Paper Case Studies

This repository contains the input data used in the case studies presented in the paper:

Integrated Investment and Operational Planning for Sugarcane-Based Biofuels and Bioelectricity under Market Uncertainty

The data provided here allows researchers and practitioners to reproduce the case studies of the paper using OptBio, an open-source optimization package developed in Julia for analyzing the sugarcane biomass supply chain and derived products.

The repository provides:

  • A .optbio file (SQLite database) with all model input data.
  • A set of .csv files with scenario data (e.g., prices, availability).

⚙️ How to use

  1. Install OptBio
    Follow the installation instructions in the official documentation.

  2. Clone this data repository
    Clone this repository (e.g., in your working directory or inside the OptBio folder):

    git clone https://github.com/psrenergy/OptBio-case-studies.git
  3. Run the case studies
    From the OptBio environment, run:

    using OptBio
    
    OptBio.main(["OptBioPaperCaseStudies/case1/case1.optbio"])

    The above command runs the first case study. You can replace the path with the path to other case studies (e.g., case2, case3, etc.). The results folder will be created in the same directory as the .optbio file.
