Abstract:
1. A system for designing a sensor arrangement for an automated system, the system comprising a configuration unit having a processor; a first input unit coupled to the configuration unit for receiving a specification of a plurality of sensor measurements to be carried out by the sensor arrangement; wherein the sensor measurements are indicative of a measurement of a parameter sensed by one or a plurality of sensors of the sensor arrangement; wherein the parameter is adapted for monitoring or controlling the automated system; a second input unit coupled to the configuration unit for receiving a specification of a confidence region together with an associated confidence level for each of the specified sensor measurements; wherein the confidence region is indicative of an interval for a plausible physical value of the parameter; wherein the confidence level is indicative of a probability that the value of a sensed parameter detected by a respective sensor measurement deviates from a true value of the sensed parameter by less than a value indicated by the confidence region; and a third input unit coupled to the configuration unit for receiving a specification of a target confidence level for the automated system; wherein the target confidence level is indicative of a probability that the automated system fails; and wherein the 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 generates a representation of a sensor arrangement.
