Sensitivity analysis意思

Sensitivity analysis is a technique used in risk analysis and decision making to determine how the output of a model or system changes given changes in the input variables. It is used to identify which input variables have the most significant impact on the output, and to understand the magnitude of the impact.

In other words, sensitivity analysis helps to answer the question: "How much does the output of the model change if the value of an input variable changes?"

For example, if you are building a financial model to evaluate the profitability of a new product, you might use sensitivity analysis to understand how changes in sales volume, cost of goods sold, or interest rates would affect the overall profitability of the product.

Sensitivity analysis can be used in a wide range of fields, including engineering, finance, economics, and environmental science. It is often used in conjunction with other risk analysis techniques, such as scenario analysis or Monte Carlo simulation.
