Optimal sensor placement for fault detection

This paper describes an approach to fault detection and classification usin g neural networks and methods of combinatorial optimisation. Given the exis tence of an effective fault detection procedure, the problem arises as to h ow the sensors should be placed for optimal efficiency of the detector. In this paper, a neural network is used to locate and classify faults and a nu mber of different methods are applied to determine an optimal (or near opti mal) sensor distribution.
