In this chapter a multiple criteria method (MCM) is presented and tested for finite-element-model updating using a simple beam with holes and an irregular H-shaped structure. The MCM minimizes the Euclidean norm of the error matrix that combines the modal property data with the frequency-response function data. The results given by the MCM are compared with the results from a frequency-response function method (FRFM), and those obtained from the modal property method (MPM). The three methods were compared based on their ability to reproduce the measured parameters. It was observed, on average, that the MCM gives the best results.
