Sensitivity analysis, which assesses how modifications to input parameters impact a model's optimal solution, is essential to operations research decision-making. Decision-makers can concentrate on crucial areas that need attention or modification by determining which variables have the most effects on results. Strategies for risk management and resource allocation under uncertainty are informed by this analysis, which aids in evaluating the robustness of solutions. In the end, sensitivity analysis improves an organization's operational resilience and effectiveness by enabling it to make well-informed, flexible decisions in response to changing circumstances.
