Sensitivity analysis techniques help decision-makers understand how changes in variables affect outcomes. From one-way analysis to Monte Carlo simulations, these methods reveal which factors matter most. Tornado diagrams visually rank variables by impact, guiding where to focus efforts.
Risk assessment tools aid in evaluating decision alternatives under uncertainty. quantifies the worth of reducing uncertainty. Various risk measurement techniques and decision criteria help managers navigate complex choices while considering their risk preferences.

1 of 3
varies one variable at a time observing changes in optimal decision (interest rates)
varies two variables simultaneously creating 2D graph visualizing decision regions (price vs demand)
identifies point where optimal decision changes (break-even point)
evaluates best-case, worst-case, and most likely scenarios (economic boom, recession, steady growth)
generates random values for uncertain variables running multiple iterations to assess overall impact (stock market fluctuations)
Critical variables in tornado diagrams
construction lists variables on vertical axis showing impact range on horizontal axis
Variable ranking orders variables from most to least impactful
Calculate outcome for each variable's high and low values
Sort variables by impact magnitude
Applications in decision-making focus on high-impact variables for further analysis allocate resources to reduce uncertainty in critical variables (market demand, production costs)
Risk Assessment and Decision-Making
Expected value of perfect information
maximum amount decision-maker would pay for perfect information
Calculation of EVPI EVPI=EVPI−EVmax where EVPI is expected value with perfect information and EVmax is expected value of best alternative without perfect information
for EVPI constructs decision trees with and without perfect information comparing expected values
Applications of EVPI determine value of additional research or data collection assess whether to invest in reducing uncertainty (market research, geological surveys)
Limitations of EVPI assumes decision-maker may overestimate value of information in practice
