Design of DSS with Information Feedback
含决策状态反馈的DSS设计

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.
