Simulation framework –
working definitions
A simulation scenario is a perspective created in the Simulation Console by the composition of: a set of time ordered events that are processed by the SE and visualized in the SC in the timeline a set of virtual devices (instances (instances of virtual device classes defined by the user) a set of real devices (installed at the facility level, recognized and controlled by the SBC through the corresponding web services)

Simulation framework –
working definitions
A schedule is an executable instruction set for the control of physical devices and device groups actions are associated with certain time intervals (e.g. days of the week)
A policy is a set of rules: ON (Trigger) IF (Condition) THEN {Block of actions} ELSE {Block of actions}

Simulation framework –
working definitions
Policy examples: “If earthquake warning is active, stop all elevators at closest floor.”
Low level:
High level:
“If earthquake alarm active and occupancy < 40% and security understaffed, then apply emergency evacuation protocol number 6.”

Case study Testing the response of a Smart Building Controller – steps: define the events in the simulation scenario to be sent to the Smart Building Controller - as external events corresponding to the events list defined in the SBC define the simulation scenario in the Simulation Console including real devices in the building infrastructure recognized and controlled by the SBC and models of the virtual devices through the Simulation Bridge define the policies and schedules for the Smart Building Controller operation, through the Policy Editor execute simulation scenario in the Simulation Console and inspect the SBC’s execution logs

Case study – define a simulation scenario Q: What do we want to simulate ? Q: Given a set of rules that specify the behavior of the SBC in a real EarthquakeAlarm situation, how to test this scenario without a real alarm occurring ? A: We use the FCINT Simulation framework to create a scenario in the Simulation Engine. Idea: Have the Simulation engine “pump” EarthquakeAlarms to the SBC

Case study – define a simulation scenario there are no physical devices to control in case of an EarthquakeAlarm event, yet installed in the SBC we use the Simulation Bridge to create virtual devices for the policies to act upon virtual devices are treated by the SBC the same way as real devices, via the web services interface
use the Simulation Bridge to create, expose and allow the SBC to control the following virtual devices: GasSwitch (state: int = 0/1) Light1, Light2, Light3 (state: int = 0/1) EarthquakeAlarm (running: int = 0/1)
