What is Sensitivity Analysis?

Sensitivity Analysis is a powerful tool used to understand how different values of an independent variable impact a particular dependent variable under a given set of assumptions.

It allows decision-makers to predict the outcome of a decision if a key input or assumption changes, ensuring that the decisions made are robust and can withstand variations in the underlying data or assumptions.

Importance of Sensitivity Analysis

The dynamic nature of decision-making often means that assumptions, forecasts, or input values can change. Sensitivity Analysis is crucial because:

  • Robust Decision-Making: It ensures that decisions are not just based on a single set of assumptions but can stand up to changes in these assumptions.
  • Uncertainty Management: Sensitivity Analysis helps in identifying which variables have the most significant impact on the outcome, allowing decision-makers to focus on these variables and manage uncertainties better.
  • Confidence in Decisions: By understanding the range of potential outcomes and how changes can impact these outcomes, decision-makers can have greater confidence in their choices.
  • Stakeholder Communication: Sensitivity Analysis provides a transparent way to communicate to stakeholders how different scenarios can impact the decision, ensuring that everyone is on the same page.

Key Concepts of Sensitivity Analysis

Variables

Highlighting the inputs or factors that may change and impact the outcome of a decision, emphasizing the dynamic nature of decision-making environments.

Scenario Analysis

Demonstrating the process of changing one or more variables to see how it impacts the outcome, illustrating the adaptability and dynamic nature of sensitivity analysis in accommodating different scenarios.

Stability Intervals

Focusing on the ranges within which the decision or outcome remains stable despite variations in input variables, offering insights into the robustness and reliability of decisions under uncertainty.

Applying Sensitivity Analysis in Multi-Criteria Decision Analysis (MCDA)

In the context of MCDA, Sensitivity Analysis plays a crucial role in understanding how changes in weights or scores of criteria can impact the final decision. Given that MCDA involves multiple criteria, it’s essential to know how sensitive the results are to changes in these criteria.

Steps to Apply Sensitivity Analysis in MCDA

Identify Key Criteria

Start by identifying which criteria are most uncertain or which ones you believe might have the most significant impact on the decision.

Vary the Weights

Adjust the weights of these key criteria to see how they impact the final decision. For instance, if environmental impact has a weight of 0.7, what happens if it’s increased to 0.8 or reduced to 0.6?

Analyze the Results

Examine how the final decision or ranking of alternatives changes when the weights or scores of criteria are varied.

Report Findings

Document the results of the Sensitivity Analysis, highlighting any criteria that significantly impact the decision.
