空间决策支持系统的数据集成方法 总被引:4,自引:0,他引:4
地理信息系统(GIS)与决策支持系统(DSS)各自发展多年,有了很多成型的实例。空间决策支持系统(SDSS)是在这两个系统的基础上发展起来的一种新的模式,将地理信息与决策信息相结合,提出了架构在空间信息上的决策支持系统,使决策更具体、更形象、更生动。文章从开发空间决策支持系统的实际经验出发,以数据集成为切入点,系统地阐述了GIS与DSS在SDSS中的集成方法。 相似文献

One of the most important stages of group decision-making is the generation and identification of decision tasks. In this paper, we define a decision task with five elements: decision makers, decision executors, decision objectives, decision problems and decision constrains. Based on this distinction, we present a conceptual model for generation and identification of group decision tasks in an organization. In addition, we describe a prototype of a group argumentation support system (GASS) that applies frame-based information structure in electronic brainstorming (EBS) and argumentation to support group decision task generation and identification. Using four group performance indicators, the prototype was evaluated in a lab experiment to determine its effectiveness and efficiency. 相似文献

疏勒河流域水资源管理决策支持信息系统设计 总被引:4,自引:0,他引:4
世界银行贷款的疏勒河农业综合开发暨移民安置工程的实施,使流域内水土资源得到了极大规模的开发与利用,但同时也产生了湿地萎缩、植被退化、土地沙化和盐渍化等一系列较为严重的水环境问题。为实现流域整体生态、社会、经济效益的统一,保证区域经济与社会的可持续发展,建立科学、可靠、操作性强的流域水资源管理决策支持信息系统是实现上述目标的根本保障。在分析系统需求的基础上,结合疏勒河流域水资源特点对系统的结构、系统功能、系统实现等方面进行了
初步探讨,认为疏勒河流域水资源管理决策支持信息系统应是一个以硬件、系统软件、组织机构以及水资源数据为基础,“3S”技术及水资源管理专业模型为支撑的,集数据的采集、传输、存储、管理、分析、决策、输入、输出为一体的集成系统,以进行疏勒河流域水资源的评价、科学管理和决策。 相似文献

This paper reports on a decision-making model that can be used for group argumentation when decisions contain twofold complexities: the problem itself and the people (i.e., the decision makers). Related studies have been well documented in literature; however, research on the group mechanism remains limited with regard to two aspects: (1) the complexities of problems and people and (2) the interaction manners of opinions derived from people. In this study, we develop a mechanism called the complex group argumentation (CGA) framework for group decision making. This solution applies the classic methodology of system designs, that is, qualitative-to-quantitative metasynthesis, and contains two core processes, namely, complexity resolution and group argumentation. From a practical perspective, we evaluate the performance of the CGA framework in the context of supplier selection (SS). Results show that our approach can satisfy the requirements of practical SS, while simultaneously coping with the disadvantages of real-world complex GDM. The results of this research can inspire studies on group argumentation in academics and provide proposals for mechanisms on the development of group support systems in the industrial community. 相似文献

Participatory spatial planning and decision making requires a combination of software tools for group decision support, individual decision support and geographic analysis and presentation. This article presents a respective approach that integrates two software tools which were originally developed independently. One tool, Dito, is a Java application for the World Wide Web designed to facilitate structured argumentation and discourses. The other tool, CommonGIS, provides Java-based web-enabled services for the interactive, explorative generation and analysis of thematic maps, and it also supports multi-criteria decision making. The evolution of the integrated system is reviewed from first experiments in 2001, the resulting requirements and a succession of prototypes up to the latest solution. The focus of the article lies in the design of this solution. 相似文献

Nowadays, many websites allow social networking between their users in an explicit or implicit way. In this work, we show how argumentation schemes theory can provide a valuable help to formalize and structure on-line discussions and user opinions in decision support and business oriented websites that held social networks between their users. Two real case studies are studied and analysed. Then, guidelines to enhance social decision support and recommendations with argumentation are provided. 相似文献
