We present the results of a population synthesis of radio and gamma-raymillisecond pulsars (MSPs) from the Galactic Disk (GD). Using 92 radiomillisecond pulsars detected in 13 radio surveys and 54 Fermi MSPs detected aspoint sources in the first point source catalog, we establish six freeparameters corresponding to the overall factor and the exponents of the periodand period derivative dependence for each of the radio and gamma-ray empiricalluminosity models. We test three high-energy emission models described by thetwo pole caustic Slot Gap, Outer Gap, and Pair Starved Polar Cap geometries.The simulated distributions of pulsar properties adequately describe thedistributions of detected MSPs from the GD. We explore the gamma-ray emissionfrom groups of MSPs in globular clusters and in the Galactic Bulge. Thesimulation predicts reasonable numbers of Fermi MSPs detected in the otherpoint source catalogs and anticipates a bright future for Fermi observations ofMSPs, expecting a total of ~ 170 MSP detections from the GD within ten years.Our numbers of simulated MSPs in globular clusters are in agreement with thosederived from Fermi detections. The simulation predicts about 11,000 MSPs in theGalactic Bulge are required to explain the gamma-ray Galactic Center Excess.
