AB  - The Juelich Electric Dipole moment Investigations (JEDI) collaboration in Juelich ispreparing a direct EDM measurement of protons and deuterons first at the storage ring COSY(COoler SYnchrotron) and later at a dedicated storage ring. Ensuring a precise measurement,various beam and spin manipulating effects have to be considered and investigated.  Adistortion of the closed orbit is one of the major sources for systematic uncertainties. Thereforemisalignments of magnets and residual power supply oscillations are simulated using the MAD-X code in order to analyse their effect on the orbit. The underlying model for all simulationsincludes the dipoles, quadrupoles and sextupoles at COSY as well as the corrector magnets andBPMs (Beam Position Monitors). Since most sextupoles are onlyused during beam extraction,the sextupole strengths are set to zero resulting in a linear machine. The optics is adjusted in away that the dispersion is zero in the straight sections. The closed orbit studies are performedfor deuterons with a momentum of 970 MeV/c.
