THE EVOLVING ROLES OF MODELS IN DECISION SUPPORT SYSTEMS*
回顾了多个代表性决策支持系统，说明模型在其中角色的演变，并指出设计者需考虑三个主要接口，依赖两类语言（计算指令与数据操作），为系统分类和未来研究提供框架。
Abstract An important aspect of decision support systems (DSS) is their utilization of computational models. To illustrate the evolving roles of models in decision support systems, several representative systems are reviewed. These illustrations reveal three major interfaces that must be considered by a decision support system's designer. Successful treatment of these DSS interfaces depends upon two types of languages: one for directing computations and one for directing data manipulation. Each language type is presented as forming a spectrum of languages. Combined, the two spectra provide a classification scheme for decision support systems. This scheme is both useful as a framework for comparative study of decision support systems and also suggestive of directions for future research and developments in the decision support field.
