untilperfect

The untilperfect application solves the buffer preparation vessel sizing and assignment problem using mixed integer linear programming.

The source repo is at https://github.com/multipitch/untilperfect.

Builds are hosted at https://pypi.org/project/untilperfect/.

Documentation is hosted at https://untilperfect.readthedocs.io/.

This project was forked from https://github.com/multipitch/dissertation. The dissertation repo was created for my masters dissertation on the subject towards an MSc in Business Analytics from University College Dublin; further development has been forked here so that the dissertation repo remains frozen.

Install via pip:

$ pip install untilperfect

Provides the untilperfect CLI command

$ untilperfect --help
usage: model.py [-h] [-b BUFFERS] [-n] [-p PARAMETERS] [-f PATH] [-s SOLVER]
                [-t PROBLEM_TYPE] [-v VESSELS] [-w]

Solves the buffer preparation assignment and selection problem.

optional arguments:
-h, --help            show this help message and exit
-b BUFFERS, --buffers BUFFERS
                      buffers filename (default: 'buffers.csv')
-n, --no-plot         do not generate plot
-p PARAMETERS, --parameters PARAMETERS
                      parameters filename (default: 'parameters.ini')
