  "abstract": "We present a comprehensive study of the timing resolution achievable in plastic scintillator detectors read out through wavelength-shifting (WLS) fibers coupled to silicon photomultipliers (SiPMs), combining a semi-analytical framework, toy Monte Carlo validation, and full Geant4 optical photon simulation. The analytical model traces the complete photon detection chain: scintillation emission, WLS fiber re-emission, optical transit time dispersion, SiPM single-photon time resolution, and electronics quantization. It expresses the timing resolution $\\sigt$ as a function of the detected photoelectron yield $\\Npe$, scintillator decay constants ($\\taur$, $\\taud$), WLS re-emission time ($\\tauwls$), fiber numerical aperture, detector geometry, and readout electronics parameters. The analytical predictions are validated at two levels. First, toy Monte Carlo simulations ($2\\times 10^5$ events per parameter point across 80 grid points spanning 8 fiber types and $\\Npe$ from 5 to 200) achieve analytical-to-MC agreement of \\add{$1.0000 \\pm 0.0018$}. Second, full Geant4 optical photon simulations track the entire scintillation, wavelength-shifting, and fiber transport chain in realistic detector geometries, confirming the analytical timing predictions\\add{ to within 10--20\\% for $\\Npe \\gtrsim 10$} and providing first-principles photoelectron yield calibration. A comprehensive parameter scan covering 7 scintillator materials, 8 WLS fiber types, 5 SiPM models, 5 electronics configurations, 3 readout topologies, and 3 boundary conditions produces quantitative design maps and lookup tables for detector optimization.",
