Sensitivity Analysis

Definition

Sensitivity analysis is a technique used to determine how the variation in the output of a model can be attributed to different variations in its inputs. It plays a crucial role in assessing risk and uncertainty, helping decision-makers understand which variables have the most impact on outcomes, thus informing better choices.

5 Must Know Facts For Your Next Test

1. Sensitivity analysis helps identify critical variables that significantly affect a model's outcome, guiding strategic planning and resource allocation.
2. It can be applied in various fields including finance, supply chain management, and operations to evaluate how changes in input variables impact profit margins or costs.
3. Performing sensitivity analysis can reveal the robustness of models and forecasts by showing how much outputs would change in response to input variations.
4. This technique is especially valuable when evaluating forecast accuracy, as it can highlight which assumptions or data points have the highest uncertainty.
5. In optimization modeling, sensitivity analysis aids in understanding how changes in constraints or parameters can affect optimal solutions.
