The Data Preparation Package (DPP) is a software package for the regression of thermophysical property models. Using a plugin interface any kind of thermodynamic model could be used for the calculation of thermophysical properties.
The DECHEMA Data Preparation Package (DPP) is part of the DETHERM Software Suite. It closes the gap between raw thermophysical data and model based process simulation packages. It allows
The main components of DPP are
The optimizer is able to calculate a common objective value over n sets of data grouped in m blocks . For each of the m blocks a seperate objective and also error function can be used. To minimize the calculated objective value, the model parameters will be varied. This approach enables the DPP system to correlate simultaneous different data types using different error functions (e.g. to correlate VLE, LLE, HE, gammy infinity and azeotropic data all together). In each case the approach can be combined with a Maximum-Likelihood Algorithm for generation of the "true" values.
