We design and develop a Web Application and its system for the Hamburg Innovation GmbH's Onshore Power Project. The Project Onshore Power Supply Planning project concerns the provision and validation of onshore power supply plans based on mathematical optimization models to maritime ports. The project team is preparing the creation of a spin-off firm from the University of Hamburg with the support of Hamburg Innovation GmbH. The services are supported with a website/web application (system). The web application introduces users to the services as well as provide a way to use project’s services.
