All simulation, optimization, and analysis engines share a single What-If API. Ask any "what happens if..." question — the platform automatically selects the right engine, runs baseline vs. modified scenarios, and returns results with confidence intervals.
Simulation: Discrete Event Simulation, Agent-Based Modeling, Monte Carlo, System Dynamics
Optimization: NSGA-II multi-objective, MILP exact solving, Genetic Algorithms, Bayesian search, CP-SAT constraint solving
Prediction: Holt-Winters forecasting, Kalman filtering, Conformal Prediction intervals
Analysis: Causal inference (DoWhy), Survival analysis, Weibull reliability, DOE/Sobol sensitivity
The key advantage: for the same problem, FactVerse can simultaneously run Erlang-C (analytical solution) + DES (simulation validation) + Monte Carlo (stress testing) + Network Flow (bottleneck analysis) — four perspectives cross-validating each other. This is physically impossible with human analysts.
