1 INTRODUCTION Model order reduction (MOR) has achieved much success in many areas of computational science with its capability of realizing real-time simulation and providing accurate results. Different MOR methods, their applications, and the promising results they produce can be found in the survey papers1-3 and books.4-9 MOR usually needs an offline stage for constructing the reduced-order model (ROM).

The aim of this study is to improve the performance of a wire fault diagnosis approach based on time-domain reflectometry (TDR). In this approach, the TDR response collected from measurements for a given (faulty) coaxial cable network is used as a reference for the cable network model response computed by an accurate analytical transmission line (ATL) method. The ATL model is iteratively tuned according to the outcome of the optimisation algorithm proposed.
