      abstract     = {Cost functions in optimisation processes are used as a
                      measure to compute the distance between two data sets.
                      Commonly, the root mean square error is used as a cost
                      function for the estimation of material parameters based on
                      bench-scale experiments. Due to the noise and variance in
                      the target experimental data, this may not be the best
                      choice. This contribution presents three other approaches,
                      which are implemented into the PROPTI framework. Their
                      application is demonstrated on experiments with a PMMA
                      sample in a controlled atmosphere pyrolysis apparatus (CAPA
                      II). Although, in the specific case investigated here, the
                      impact of the various cost function classes is small, a
                      benefit is expected for other samples with varying
                      complexity.},
