Docker Application to solve Vehicle Routing Problem using OpenRouteService and VROOM

TSP Travel Salesman Problem

1 vehicle 2 optimal routes to cross all positions

VRP Vehicle Routing Problem

2 Vechicles, the numbers above the markers represent the quantity of material to be loaded on the vehicle

VRP Delivery

3 Vehicles that deliver material of various quantities

Enable ORS proxy

ors-proxy is a work-around to manage osm road restrictions in vroom results

---------    -------------    ---------    -----------
|  ORS  | <= | ORS-PROXY | <= | VROOM | <= | JUPYTER |
---------    -------------    ---------    -----------
                    |             ^             ^
                    v             |             |
                LOGGING       config.yml    test.ipynb

To test restrictions use this volume: ./data/mezzocorona_restrictions.osm.pbf:/ors-core/data/osm_file.pbf

run ors-proxy service: docker-compose up -d ors-proxy

and in file vroom/conf/config.yml replace 'ors' with 'ors-proxy' port 9090

Setup

Download this reporitory

git clone https://github.com/DigitalCommonsLab/docker-ors-vroom.git
cd docker-ors-vroom

docker-compose up -d

first time the images building require some minutes... first time graphs generation require some minutes... and require one restart of container

monitoring of routing engines

docker logs -f smartbin-ors

monitoring data packets from VROOM to ORS(optional require ors-proxy started) configure VROOM to port 9090

docker-compose logs -f ors-proxy

Testing OpenRouteService API

vehicles actives: "hgv","car" look at /ors/conf/app.config

check if running, brownser in:

http://localhost:8080/ors/health

Testing VROOM API

brownser in: http://localhost:8081/optimization

if respose is http 200 ok, http://localhost:8081/optimization/health

Testing OpenRouteService in Map

brownser in: http://localhost:8082

Testing VROOM in Map

upload json file problems inside jupyter/data/xxx.json

brownser in: http://localhost:8083

Testing Algorithms in Jupyter notebook

• ./jupyter/test.ipynb python notebook to test Routing Algorithms by OpenRouteService python binding

brownser in: http://localhost:8084

VROOM 1.8 with Shipments feature

load test3.ipynb notebook to test

https://github.com/VROOM-Project/vroom/blob/master/docs/API.md#shipments

Testing OpenRouteService via python(inside Jupyter)

OpenRouteService python binding, clone or install via pip https://github.com/DigitalCommonsLab/openrouteservice-py

pip install openrouteservice

import openrouteservice as ors

client = ors.Client(base_url='http://ors:8080/ors', key='')

#TSP only openrouteservice routing engine
route = client.directions(...)

#VRP vroom vrp engine
routes = client.optimization(...)

Create random testing data for VROOM

simple VRP problem to test vroom instance(on port 3000)

brownser in: http://localhost:8083

git clone https://github.com/VROOM-Project/vroom-scripts.git

cd vroom-scripts/src/

./random_problem.py -j2 --top 46.07 --bottom 46.02 --left 11.14 --right 11.18

TODO

include custom parameters in file ./ors/HeavyVehicleFlagEncoder.java
