Lyapunov Stability Analysis of the NIW Petition System A Comprehensive Model for Dynamic System Behavior

Introduction This study investigates the stability of the NIW petition system using Lyapunov theory. We model the backlog dynamics over time and explore factors such as policy shifts, corporate strategies, and automation that influence stability.

Lyapunov Function Definition The proposed Lyapunov function: V(B, ẋ) = α(B(t))² + β(ẋ(t))² • B(t)²: Reflects the backlog size (system load). • ẋ(t)²: Captures fluctuations in backlog changes. • α, β > 0: Weight parameters balancing the impact of backlog size and change rate.

Derivative Calculation dV/dt = 2[αB(t) + βẍ(t)]ẋ(t) For stability: αB(t) + βẍ(t) ≤ 0 The system is stable if both backlog size and its rate of change are controlled.

Stability Conditions • Stable: c(t) > r(t) → Backlog decreases. • Marginally stable: c(t) = r(t) → Backlog constant. • Unstable: c(t) < r(t) → Backlog grows, instability. Controlling backlog size and fluctuations is critical for stability.

Impact of External Factors • Corporate Strategies: Shift from PERM to NIW inflates receipt rates. • Economic Fluctuations: Layoffs increase NIW applications. • Technological Interventions: Automation improves completion rates, stabilizing the system.

Conclusion The Lyapunov function provides a robust framework for evaluating system stability. Controlling both backlog size and its rate of change is essential to maintain stability under dynamic conditions. Policy shifts, corporate strategies, and automation significantly impact stability.
