摘要

Decision analysis use sensitivity analysis to identify influential variables, to determine which input variables to model stochastically, and to characterize scenarios that could affect a change in the rank ordering of the alternatives. A frequently recommended sen- sitivity analysis technique is "one-way" sensitivity analysis, which determines a vari- able's influence by the degree to which the objective function changes as that variable is varied while all other variables are held fixed. Disadvantages of one-way analysis are that it measures the influence of only one variable at a time and it assumes independence among the input variables.
