The development of multi-object spectrographs for use in radial velocity surveys is expected to increase the detection rate of extra-solar planets by at least an order of magnitude. The dramatic increase in data acquisition requires that a robust method be developed which is able to adequately screen the data for planet candidates. We present simulations of the expected results from a generic multi-object survey based on calculated noise models and sensitivity for the instrument and the known distribution of exoplanetary system parameters. This is applied to a survey of several fields using the W.M. Keck Exoplanet Tracker instrument, the design of which utilises a dispersed fixed-delay interferometer, which is currently being used on the Sloan Digital Sky Survey 2.5m telescope. We have developed code for automatically sifting and fitting the planet candidates produced by the survey to allow for fast follow-up observations to be conducted. The techniques presented here may be applied to a wide range of multi-object planet surveys.
