This thesis presents a novel model-based fault detection 
system specifically designed to offer improved fault 
detection for the reverse pilot of cable television networks. 
The approach, however, is general and can be applied to a 
variety of large scale engineering plants. For the modeling 
part of the system, feedforward neural networks and statistical 
analysis techniques are employed. A description of these 
techniques as well as the fault detection methodology used 
is provided. Finally, this thesis presents the results of a 
large scale experiment on which the fault detection properties 
of the developed technique were evaluated and compared to those 
of limit checking fault detection.
