sensitivity analysis A formalized procedure to identify the impact of changes in various model components on model output. Sensitivity analysis is an integral part of simulation experimentation and may influence model formulations. It is commonly used to examine model behaviour. The general procedure is to define a model output variable that represents an important aspect of model behaviour. The values of various inputs of the model are then varied and the resultant change in the output variable is monitored. Large changes in the output variable imply that the particular input varied is important in controlling model behaviour. Within this general definition, sensitivity analysis has been applied to a variety of model inputs including state variables, environmental variables and initial conditions (描述在模型输出中模型部分的变化影响模式公式化的过程。灵敏度分析是模拟实验的集成并且可能影响模型公式。它通常用于测试模型的行为。通常的过程是定义一个能说明模型行为的重要部分的模型输出变量。模型有很多不同的输入值，随之变化的输出值被监测。输出变量的很大变化说明相关的输入的变化对控制模型的行为非常重要。在这个通用的定义中，灵敏度分析用于很多模型输入，包括状态变量、环境变量和初始条件。) |
