OPTIMAL-DESIGN OF A DIAGNOSIS SYSTEM FOR FAULTY SENSORS

A problem of optimal design of a diagnosis system for faulty sensors i s formulated as a problem of minimizing the cost required to construct the allocation of sensors which realizes the required upper limit of probability of false-alarm, lower limit of systematic error and upper limit of probability of mis-alarm for the given set of sensors to be d iagnosed. A concept of critical detectability is introduced correspond ing to the degree of freedom of the sensor system and a method is pres ented to solve this problem by use of this concept and the branch-and- bound algorithm.
