System architecture of the activity chain optimization application

In order to optimize daily activity chains a new approach has to be followed when creating the method and the connected systems architecture. The elaborated method builds on the flexibility of activities, which can be spatial or temporal. With the introduction of flexibility new locations of the activities are suggested to the travellers, so that the optimization can be realized and shorter travel times can be achieved. But having a novel algorithm is not sufficient, as the framework of the implementation needs to be elaborated. The system architecture of the application was designed, which provides a structure for the elaborated optimization module. The core of the system architecture is the optimization module, which contains the logic of the optimization algorithm. In the elaborated structure the following main elements were identified: mobile application, database server, application server and external databases. The functionalities and connections among the main elements were described. Furthermore the update frequencies of the external databases for proper functioning were specified.
