RSSched Getting Started

In the following you will find a step-by-step instruction how to use the RSSched programs.

To keep your home clean create a project directory rssched.

mkdir rssched
cd rssched

1. Start Solver-Server

First, we start the solver-server.

  1. clone the rssched-solver repository into the rssched directory:  

    git clone git@github.com:rolling-stock-scheduling/rssched-solver.git
cd rssched-solver

  2. install the docker engine: https://docs.docker.com/engine/install/

  3. building the docker image (from the rssched-solver-directory):

    docker build --tag eth_scheduling_image .

  4. loading the image and running the server for the first time (removes old container of the same name):

    docker run --rm --env RAYON_NUM_THREADS=16 --publish 3000:3000 --name eth_scheduling_server eth_scheduling_image

    Here, the server can use 16 threads and answers on port 3000.

2. Run MATSim-Client

Next, we generate a solver-request from a MATSim run output and send it to the solver-server.

  1. Open a new terminal, navigate to rssched and clone the rssched-matsim-client and the rssched-solver repository:

    cd ~/rssched
git clone git@github.com:rolling-stock-scheduling/rssched-matsim-client.git
cd rssched-matsim-client

  2. Put your MATSim run output files, including

    • *.output_config.xml

    • *.output_events.xml.gz

    • *.output_network.xml.gz

    • *.output_transitSchedule.xml.gz

    • *.output_transitVehicles.xml.gz

      together with the config file containing the solver parameters

    • *.rssched_request_config.xlsx

    into the directory that is specified next to the matsimInputDirectory field on the first page of *.rssched_request_config.xlsx.

    As an example you can use the Kelheim instance that is located in integration-test/input/de/kelheim/kelheim-v3.0/25pct/.

    Since the kelheim-v3.0-25pct.output_events.xml.gz is too large for git use the following command to download them from the official repository or use this link for a manual download.

    wget https://svn.vsp.tu-berlin.de/repos/public-svn/matsim/scenarios/countries/de/kelheim/kelheim-v3.0/output/25pct/kelheim-v3.0-25pct.output_events.xml.gz
mv kelheim-v3.0-25pct.output_events.xml.gz integration-test/input/de/kelheim/kelheim-v3.0/25pct/

  3. Build and run the rssched-matsim-client via mvn (you can use the maven-wrapper .mvnw if maven is not installed) to generate a solver-request and send it to the solver-server:

    ./mvnw clean install -DskipTests -DskipITs
./mvnw exec:java -Dexec.args="integration-test/input/de/kelheim/kelheim-v3.0/25pct/kelheim-v3.0-25pct.rssched_request_config.xlsx"

    As soon as the request is sent to the server you can observe the output of the solver within the server terminal.

    The final output (the rolling stock schedule) can be found at integration-test/output/de/kelheim/kelheim-v3.0/25pct/rssched_kelheim-v3.0-25pct/it_config/it_config.kelheim-v3.0-25pct.scheduler_response.json or what ever path is specified next to the outputDirectory on the first page of *.rssched_request_config.xlsx.

    For convenience, lets copy the schedule file to the rssched directory:

    cp integration-test/output/de/kelheim/kelheim-v3.0/25pct/rssched_kelheim-v3.0-25pct/it_config/it_config.kelheim-v3.0-25pct.scheduler_response.json ../schedule.json

3. Analysis

Finally, we visualize the schedule for analysis.

  1. Clone the rssched-analysis repository:

    cd ~/rssched
git clone git@github.com:rolling-stock-scheduling/rssched-analysis.git
cd rssched-analysis

  2. Install poetry a package manager for python: https://python-poetry.org/docs/

  3. Install the dependencies for this project via:

    poetry install

  4. Create the plots (which will open automatically in a browser):

    poetry run rssched-plot ../schedule.json

4. Clean Up

To stop the Docker-container running the solver-server use:

docker stop eth_scheduling_server

This may take a couple of seconds.

For removing the RSSched programs simple remove the rssched directory with

cd ~
rm -rf rssched
