jsprit
jsprit is a java based, open source toolkit for solving a set of well-known vehicle routing problems (VRP). It is lightweight and easy-to-use, and based on heuristics currently solving
- Capacitated VRP
- Multiple Depot VRP
- VRP with Time Windows
- VRP with Backhauls
- VRP with Heterogeneous Fleet
- Time-dependent VRP
- Various combination of these types
Setting up the problem, 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 MATSim 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.
##In Development
- continues improvement of code, handling and performance
- relaxed API to easily build algorithms from scratch
- VRP with pickups and deliveries

##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 of one of these thousands algorithms.
Second, it is motivated by my PhD-project at KIT 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, and by an awesome open-source project called MATSim and its developers.
