应用于DSS分析与设计的需求-供给-生产模型(理论篇)

The Demand-Supply-Production Model Applied to the Analysis and Design of DSS

决策支持系统(Decision Support System,DSS)是当今管理决策领域中的一类重要的计算机应用系统,其宗旨是辅助决策者解决半结构化和非结构化问题,从而提高其决策的质量。实践证明,单纯依靠结构化程序设计方法或原型法进行系统的分析与设计均难以适应DSS开发的需要。本文在实际工作的基础上将上述两种方法思想结合起来,且充分考虑了DSS的特点,提出了一种“需求——供给——生产”模型。它是一种多级嵌套模型,由外向里逐层深入则体现了系统分析与设计所应遵循的步骤序列。本文详细讨论了该模型各层的技术思想。

Either the structuring design approach or the prototyping approach can not completely meet the needs of the development of DSS. The demand-supply-production model is thus proposed based on the expriences of the design of DSS, which accepts the advantages of the above two approaches. The techniques of the model are finally presented.
