SAD (Structured Accelerator Design) is a modeling program developed and widely used in KEK. The rejuvenated TRISTAN control system uses SAD as an integrated part of the system. The main program of the rejuvenated control system, which has a graphical user interface based on X-window system on UNIX work station, uses SAD for optics calculation, beam orbit correction and orbit bump calculation. Optics data and orbit data are stored in the format which can be directly read by SAD program, so that accelerator physicists can use these data for off-line analysis using SAD. A beam base alignment method and an automated luminosity optimization program are also developed and tested in TRISTAN using the rejuvenated TRISTAN control system and SAD. Integration of SAD with the KEKB accelerator control system will be also discussed.
