<dcterms:abstract>The following work shows the application of DASPK in EcosimPro™ with the aim of to calculate&#xd;
the partial derivatives of the state variables with respect to the decision variables (sensitivities) and&#xd;
to improve the dynamic optimization. The implementation of DASPK was tested in three examples:&#xd;
disturbance rejection in a stirred tank with heater, the optimal production policy of hydrogen in a&#xd;
model of a hydrodesulfuration plant and the optimal trajectory of the feeding in a batch bioreactor.&#xd;
The sensitivities with DASPK was compared with another two possible options: obtain the gradients&#xd;
using finite differences and to solve the extended system with the analytical expressions of the&#xd;
sensitivities. The outcomes shows that the implementation of DASPK is a suitable option to ensure&#xd;
optimality in dynamics optimization without the need of writing the sensitivities by hand,&#xd;
nevertheless the CPU time must be improved to become this option attractive.</dcterms:abstract>
