Abstract: In this paper, an environment for generating user-interface of decision support system （DSS-UIGE） is described. After researching the characteristics of decision support system （DSS） and User_Interface （UI）, we designed and implemented DSS_UIGE, including screen mamagement system, hierarchy graphy management system, menu generating system, CKS-based graphy system, full screen editor and formatted data_ input tools. With the functions and characteristics of general UIMS, DSS_UIGE has been used to generate the UI of special DSS supporting decision-making using AHP （Analytic Hierarchy Process）.
