|
======
|
|
jsprit is a java based, open source toolkit for solving a set of well-known <a href="http://neo.lcc.uma.es/vrp/vehicle-routing-problem/" target="_blank">vehicle routing problems</a> (VRP).
|
|
It is lightweight and easy-to-use, and based on heuristics currently solving
|

- <a href="http://neo.lcc.uma.es/vrp/vrp-flavors/capacitated-vrp/" target="_blank">Capacitated VRP</a>
|
|
- <a href="http://neo.lcc.uma.es/vrp/vrp-flavors/multiple-depot-vrp/" target="_blank">Multiple Depot VRP</a>
|
|
- <a href="http://neo.lcc.uma.es/vrp/vrp-flavors/vrp-with-time-windows" target="_blank">VRP with Time Windows</a>
|
|
- VRP with Backhauls
|
|
- VRP with Pickups and Deliveries
|
|
- VRP with Heterogeneous Fleet
|
|
- Time-dependent VRP
|
|
- Various combination of these types
|
|
|
|
Modifying the algorithms and visualising the discovered solutions is as easy and handy as
|
|
reading classical VRP instances to benchmark your algorithm.
|
|
|
|
Additionally, jsprit can be used along with <a href="http://www.matsim.org" target="blank_">MATSim</a>
|
|
to solve the above problem-types in real networks (i.e. without preprocessing transport times and costs). A variety of least cost path algorithms such as Dijkstra and A*
|
|
can be used, and a dynamic and interactive visualiser greatly enhances the analysis.

##About
|
|
The jsprit-project is created and maintained by Stefan Schröder. It is motivated by two issues.
|
|
|
|
First, there is an almost endless list of papers and algorithms to tackle vehicle routing problems, **BUT** there are (as far as I know) only a [very few open source implementations](https://github.com/jsprit/jsprit/wiki/Other-Projects) of one of these thousands algorithms.
|
|
|
|
Second, it is motivated by my PhD-project at [KIT](http://www.kit.edu/english/index.php) where I apply vehicle routing algorithms to solve behavioural models of freight agents to assess (freight) transport policy measures.
|
|
|
|
It is mainly inspired by my research group at [KIT-ECON](http://netze.econ.kit.edu/21.php), and by an awesome open-source project called [MATSim](www.matsim.org) and its developers.
