关于决策支持系统的结构与进化

本文在总结作者开发决策支持系统的实践经验的基础上，从ＤＳＳ的结构分析入手，探讨了ＤＳＳ的进化问题，首先通过软件开发方式，程序设计风范，人工智能道路和系统科学发展等方面的深入剖析，指出了进化能力的强弱是ＤＳＳ成败的关键。其次展开了关于ＤＳＳ结构的研究，提出了ＤＳＳ的外延结构和内涵结构的新概念并进行了比较。随后讨论了ＤＳＳ的进化问题，分析了传统的第一代决策支持系统存在的缺陷，阐述了第二代和第三代决策支

On the Structure and Evolution of Decision Support Systems

Based upon the practical experience in developing decision support systems (DSS), this paper discusses its evolution problem from the viewpoint of structure analysis and points out that the ability to evolve is the key to the success of DSS. The paper also puts forward the new concepts of extensional structure and international structure, analyzes the shortcomings existed in the traditional first generation DSS, and gives the characteristics of the second and third generation of DSS. The existent DSS and evolutionary DSS are distinguished, and an important aspect of DSS research in the future is pointed out.
