A paradigm for the non-routine design of electromagnetic devices using a case based reasoning approach

The use of optimization techniques to satisfy a set of specifications is be coming more common. However, these processes may fail if the initial device , when considered,vith the specifications is "over-constrained.'' This pape r proposes an approach to identifying this form of failure through the use of Case-Based Reasoning and three inter-related models of the device (struc tural, behavioral and mathematical). When a potential failure is found, the system makes structural changes to the device to bypass the failure.
