解释：

Decision trees depend on a successful outcome in one step before moving on to the next step. Sensitivity analysis involves changing one variable at a time. Scenario analysis estimates outcomes and values under several possible fixture scenarios. Simulation is a complex tool that looks at distributions of values.

决策树依赖于一个步骤的成功结果，然后再移动到下一步。
敏感性分析涉及一次改变一个变量。
情景分析在几种可能的固定方案下估计结果和价值。
模拟是一种复杂的工具，可以查看值的分布。
