The Distribution Demonstrator enhances the existing DI Solution for distribution of media products. Functionality for automated establishment and revision of optimized distribution routes are added, as well as web-based map interaction. The EDGE VRP Solver prototype is integrated for advanced route optimization functionality. Map interaction is based on SINTEF's SVG-based map server technology.
In a similar fashion, the Waste Management Demonstrator enhances the existing TCS web-based solution for transportation management with powerful functionality for route plan optimization.
The Generic Demonstrator is built upon the versatile fleet management and route planning tool SPIDER Designer.
The EDGE VRP Solver Prototype is based on SPIDER Planner, a component for efficient resolution of a wide variety of Vehicle Routing Problems, developed by SINTEF.
Throughout the project, we survey relevant literature and state-of-the-art in transportation management technology. We also produce research papers, give talks at international conferences and arrange industry seminars.
