Operator dashboard, Web based Human System Interface
See Online demonstration: http://ttwin.techno.uwasa.fi/Dashboard
Features:• To assist decision making• Integrating information from different sources• Integrating different application (Disturbance Draw)• Displaying information in suitable for the Operator:
• user profile• positioning context• device context
Requirements for the underlying software products:• Open application programming interfaces (APIs) to integrate other applications• Web aware to enable WebServices • Location information of objects (feeders, substations etc.) should be accessible via some standard format

Summary, Conclusions and Future work
Summary:
• GUN platform was used as a future test bed for electricity distribution system
• Possible scenerios for importing and exporting information between different domains were recognized
• Utilizing the learning capabilities of agents, e.g. faults of the power network and their solutions can be shared between the agents
Conclusions:
• Interoperability, automation and integration features of GUN platform were utilized
• Context information supports expert (Operator) in decision making process
• Dashboard hides the underlying applications and WebServices that provide the online information
Future work: • More complicated features of agents and their collaboration in Multiagent system (MAS)
