Job-Shop Scheduling Environment

An optimized OpenAi gym's environment to simulate the Job-Shop Scheduling problem.

Getting Started

This repository is available as a pip package:

pip install JSSEnv==1.0.0

Once installed, the environment will be available in your OpenAi's gym environment and can be used to train a reinforcement learning agent:

import gym
env = gym.make('JSSEnv:jss-v1', env_config={'instance_path': 'INSTANCE_PATH'})

Important: Your instance must follow Taillard's specification.
