Port Activity App
Read full descriptionHide full description
The basic principle of the Port activity application is that port actors share their estimated and actual times regarding certain states in the port call process as a minimum set of data. The information sharing is to support collaborative decision making and improving information exchange between port actors, hinterland operators and ships. A large number of phone calls and emails between port actors will be reduced to a minimum with Port activity application system adding to time savings in the movement of goods. The exchange of information will avoid bottlenecks that occur in the information flow today.
