While expert systems hold great promise for decision support, currently available software packages, called decision-modelling programs, provide clinicians with analytical assistance for resolving difficult decisions. This paper describes the two general classes of computerized decision-modelling programs (decision tree analysis and multiple criteria models), and illustrates the descriptions with examples of commercially available packages. Decision tree analysis is useful when the selection of a present action (for example, a treatment) depends on some outcome in the future (i.e. the occurrence of side effects). Multiple criteria models help clinicians when the choice of action depends on satisfying many criteria simultaneously.
虽然专家系统在决策支持方面前景广阔，但目前可用的软件包，即决策建模程序，为临床医生提供分析辅助以解决棘手的决策问题。本文描述了两类计算机化决策建模程序（决策树分析和多标准模型），并用市售软件包的示例进行说明。当当前行动（例如治疗）的选择取决于未来的某些结果（即副作用的发生）时，决策树分析很有用。当行动的选择取决于同时满足多个标准时，多标准模型可帮助临床医生。
