| Abstract: | Value management (VM) has been widely used to meet challenges arising from the construction industry. However, it has also encountered some problems such as passive participation in VM workshops and a lack of time and information to complete all tasks in the workshops. A group decision support system (GDSS), entitled interactive value management system (IVMS), has been developed by the writers to overcome these problems. This paper starts with an introduction to GDSS and a critical review of technologies used in the process of idea generation in VM workshops. This is followed by findings of a laboratory experiment designed to compare the productivity of traditional brainstorming and brainstorming with IVMS support in VM workshops. The results of the experiment showed that IVMS has a positive influence on idea generation in VM workshops. Finally, the implications of the study and directions for future research are discussed. |
