pySTN

Implementation of a robust scheduling system based on STN (State-Task-Network) models.

Description

This is supporting code to reproduce the results in [1]. It allows the construction of a schedule optimizer according to the model in [2], and it also implements a robustification procedure that renders the schedules immune to uncertain events such as unit or tasks delays and swaps.

Production Network Schedules

Usage

Please refer to this IPython notebook.
