摘要
研究了含决策状态反馈 DSS的设计 ,给出了实现决策状态反馈的三种方式 ,即查询方式、响应方式和系统支持方式 ,探讨了引入反馈机制对 DSS总体结构的影响 ,具体分析了数据库子系统、模型方法库子系统和知识库子系统的反馈实现方法 ,提出了数据库反馈字段的概念 ,并在此基础上开发了相应的生产管理决策支持系统 (PMDSS) ,实践证明 ,含决策状态反馈 DSS与传统 DSS相比 ,能够极大地提高决策的有效性 .
Design of DSS with information feedback is studied in this paper.Three approaches to the implementation of the decision state feedback in DSS,inquire manner, respondence manner and system support manner,have been proposed.In addition, the effects of feedback mechanism on the structure of DSS were studied.How to carry out feedback mechanism in database subsystem, model-method subsystem and repository subsystem is analysed. The conception of feedback field is put forward, and a kind of DSS construction which is suitable for feedback was recommended.Finally,a production management decision support system(PMDSS) with information feedback was developed.
