Knowledge-Based Decision Support Systems (KBDSS) have evolved greatly over the last few decades. The key technologies underpinning the development of KBDSS can be classified into three categories: technologies for knowledge modelling and representation, technologies for reasoning and inference, and Web-based technologies. In the meantime, service systems have emerged and become increasingly imp...

This study describes the framework for developing a knowledge-based decision support system (KBDSS) for making more informed decisions for managing variation orders in institutional buildings. The KBDSS framework consists of two main components, i.e., a knowledge base and a decision support shell. The database will be developed through collecting data from source documents of 80 institutional p...

This paper describes the development of the knowledge-based decision support system (KBDSS) for management of variation orders for institutional buildings in Singapore. The KBDSS consists of two main components, i.e., a knowledge-base and a decision support shell for selecting appropriate controls. The database is developed by collecting data from the source documents of 79 institutional buildi...

§ Knowledge Media Institute, The Open University, Milton Keynes, MK7 6AA, UK; Email: [email protected] Abstract. Engineering design is a human activity using different knowledge sources. From the point of availability it is possible to distinguish well-structured, explicit knowledge as opposed to tacit, implicit and often experience-based knowledge. Each type plays a particular role in enginee...

This is a comprehensive text introducing the fundamentals of the two major fields of decision support systems (DSS) and knowledge-based systems (KBS) and how synergistic merging of the two can result in a new generation of DSS: (KBDSS). On the whole it is a refreshing change from most articles and books written on this topic which are little more than wish lists and proposals. Instead, many exa...

In a perfect world, changes will be confined to the planning stages. However, late changes often occur during construction, and frequently cause serious disruption to the project. The need to make changes in a construction project is a matter of practical reality. Even the most thoughtfully planned project may necessitate changes due to various factors. The fundamental idea of any variation man...

A recent trend in information retrieval systems technology is the development of on-line information retrieval systems. One objective of these systems has been to attempt to enhance decision effectiveness by allowing users to preferentially seek information, thereby facilitating the reduction or elimination of information overload. Since information systems users may preferentially seek informa...

Knowledge-based decision support systems (KBDSS) hold up business and organizational decisionmaking activities on the basis of the knowledge available concerning the domain under question. One of the main problems with knowledge bases is that their construction is a time-consuming task. A number of methodologies have been proposed in the context of the Semantic Web to assist in the development ...

Expert critics have been built to critique human performance in various areas such as engineering design, decision making, etc. We suggest that critics can also be useful in building and use of knowledge-based design systems (KBDSs). Knowledge engineers elicit knowledge from domain experts and build a knowledge-based design system. The system generates designs. The amount of knowledge the syste...
