This paper describes the Java-based toolkit ProFiDo which integrates several tools for fitting input models. Currently supported are command line tools for fitting probability distributions, ARIMA processes and Markovian arrival processes. The toolkit provides a graphical user interface which allows for the specification of workflows that describe the different steps of data preprocessing, parameter fitting and result visualization. The basis for the interoperability of the different tools is an XML based interchange format for the specification of various types of processes. An XML based configuration file supports the extension of the toolkit by integrating additional fitting methods or analysis approaches.
