Abstract. The Combination between Web services and software agents provides a promising computing paradigm for efficient service selection and integration of inter-organizational business processes. This paper proposes an agent-based Web DSS; the main contribution of our study is to provide an efficient tool that helps users find information resources available as an online service within Intranet. The decision-making is not only guided by the information provided by DSS but rather than the Web technology, the process is entirely based on communication between ISP Agents and Web agent. While negotiating compromises for conflict solving to share common resources, decision centres use Web service to conduct various complementary tasks. To illustrate the idea, a simple case study is given. Keywords: Decision Support System (DSS), Integrated Station of Production (ISP), Software agents, Web-based DSS.
Computer technology progress has led to widespread use of computerized support in various activities. Particularly, traditional decision support systems (DSS) focus on computerized support for making decision with respect to managerial problems. There is an emerging and fast growing interest in computerized support systems in many other domains such as information retrieval support systems, research support systems, teaching and learning support systems, computerized medical support systems, knowledge management support systems, and many more. The recent development of the Web generates further momentum to the design and implementation of support systems.
Obviously enough, there is a strong trend for studying computerized support systems especially on Web platforms. Research on information retrieval support systems, research support systems, teaching and learning support systems, decision support systems, computerized medical support systems, and knowledge management support systems are just some of their representatives.
This paper will focus on one of the important research topics of Web- based DSS and provides an efficient tool that helps users find information resources available as an online service within an Intranet. The organization of this paper is as follows. We introduce the concept of Decision Support System and Web-based support systems in the next section. Section 3 discusses issues of recent research in Web-based decision
support. In section 4 we propose our contribution. In section 5 we explain our proposed model. Section 6 shows a sample application for the Web-based DSS. Finally, a conclusion and future work are given in Section 7.
2 Decision Support System and Web Based Decision Support
2.1 Decision Support System
Before we start with detailed aspects of the issue, it is important to tackle the definition of decision support systems.
Decision Support Systems can be defined as computer technology solutions that can be used to support complex decision making and problem solving (see Shim et al. ). To account decision problems complexity and uncertainty, we understand the DSS as a set of computer-based tools that provide decision maker with interactive capabilities. It aims to enhance his understanding and information basis about considered decision problem through usage of models and data processing. The latter, in turn, allows reaching decisions by combining personal judgment with information provided by these tools. The classic DSS tool design is comprised of the components for:
• Database management capabilities with access to internal and external data, information and knowledge;
• Powerful modelling functions accessed by a model management system; and • User interfaces that enable interactive communication between...
