We address the problem of the generation of entanglement. We focus on the control of entanglement shared by two non-interacting parties A and C via interaction with a third party B. We show that, for certain physical models, it is possible to have an asymptotically complete control of the entanglement shared by A and C by changing parameters of the Hamiltonian local at site B. We present an example where different models (propositions) of physical situation, that lead to different descriptions of the system B, result into different amount entanglement produced. In the end we discuss limits of the procedure.
