Constructing a Complex Judgmental Model: An Index of Trauma Severity
基于一位医生的专业判断，应用多属性效用评估方法构建创伤严重程度指数，处理了非单调函数、指标强依赖及年龄、疾病对严重程度的影响等复杂问题。
The modeling of many complex phenomena necessarily relies on numerous interrelated judgments. This paper illustrates an application of the concepts of multiattribute utility assessment, based on the professional judgments of one physician, to scale the trauma severity of injuries to individuals. Special attention is given to problems not usually present or reported in applications of the assessment techniques. These include nonmonotonic functions, strong dependencies among different measures, and the state dependence of trauma severity on age and existing diseases of the individual. The manner in which these complexities were addressed is indicated.
