One of the central scientific goals of the next-generation CherenkovTelescope Array (CTA) is the detection and characterization of gamma-ray bursts(GRBs). CTA will be sensitive to gamma rays with energies from about 20 GeV, upto a few hundred TeV. The energy range below 1 TeV is particularly importantfor GRBs. CTA will allow exploration of this regime with a ground-basedgamma-ray facility with unprecedented sensitivity. As such, it will be able toprobe radiation and particle acceleration mechanisms at work in GRBs. In thiscontribution, we describe POSyTIVE, the POpulation Synthesis Theory Integratedproject for very high-energy emission. The purpose of the project is to makerealistic predictions for the detection rates of GRBs with CTA, to enablestudies of individual simulated GRBs, and to perform preparatory studies fortime-resolved spectral analyses. The mock GRB population used by POSyTIVE iscalibrated using the entire 40-year dataset of multi-wavelength GRBobservations. As part of this project we explore theoretical models for promptand afterglow emission of long and short GRBs, and predict the expectedradiative output. Subsequent analyses are performed in order to simulate theobservations with CTA, using the publicly available ctools and Gammapyframeworks. We present preliminary results of the design and implementation ofthis project.
