Abstract: A device for designing a sensor arrangement for an automated system, the device comprising a first input unit for receiving a specification of a plurality of sensor measurements to be carried out by the sensor arrangement, a second input unit for receiving a specification of a confidence region together with an associated confidence level for each of the specified sensor measurements, a third input unit for receiving a specification of a target confidence level for the automated system, and a configuration unit for configuring the plurality of sensor measurements and for configuring the combination of the sensor measurements in a manner to guarantee the target confidence level for the automated system.
