v1.2.0

🚀 PULPO v1.2.0 Release

🔑 Updates

1. Preliminary Documentation:

   • Docstrings have been added to all functions to provide basic guidance on usage. This documentation is preliminary and will be expanded in future releases.

2. New Database Creation Functions:

   • Two new functions have been introduced:
     • Rice Husk Example Database: Created for the Brightcon 2024 workshop purpose, but useful for general testing (data source: Kätelhön et al. (2016))
     • Generic LCI Database: A versatile tool for quick database setup, ideal for prototyping and testing.

from pulpo import pulpo
pulpo.install_rice_husk_db() # Install the rice husk example from Kätelhön et al. (2016)

project = "generic_example"
database = "generic_db"
n_prod = 50      # Number of products to generate
n_proc = 8      # Maximum number of processes per product
n_reg = 4       # Number of regions where processes can be active
n_inputs = 6    # Maximum number of inputs per process
n_flows = 8     # Number of environmental flows to generate
n_methods = 3   # Number of impact assessment methods to create
seed = 100      # Seed for reproducibility (optional)
return_data = True  # If True, returns the generated matrices

# Install the generic database with specified parameters
technosphere_matrix, biosphere_matrix, characterization_matrices = pulpo.install_generic_db(
    project=project, 
    database=database, 
    n_prod=n_prod, 
    n_proc=n_proc, 
    n_reg=n_reg, 
    n_inputs=n_inputs, 
    n_flows=n_flows, 
    n_methods=n_methods, 
    seed=seed, 
    return_data=return_data
    )

3. ipopt Compatibility:

• PULPO can now use the ipopt solver for solving the LP. This solver can be sometimes better than HiGHs. Install via:

conda install conda-forge::ipopt=3.11.1

For now, versions other than 3.11.1 lead to some unknown compatibility issues.
Specify the solver via:

results = pulpo_worker.solve(solver_name='ipopt')

🛠️ Bug Fixes

• Several minor bugs have been resolved to improve stability and performance.

Upgrade now to take advantage of the new features:

pip install --upgrade pulpo-dev

PULPO Release v1.1.0

Main changes:

• Addition of impact / indicator and environmental flow constraints
• Addition of new showcase notebooks (plastic and energy transition)
• Internal variable referencing
