In distributed Group Decision Support System (DGDSS) environment, there is a collection of sites each of which hosting GDSS database and model base. This type of setting causes possible multiple updates to be executed concurrently to data stored in the database. If these updates are not controlled, erroneous updates can occur. The design of GDSS therefore must include a mechanism to isolate one update from the effect of concurrently executing updates. This paper outlines the framework and algorithms with locking mechanism to guide the development of multi-criteria DGDSS. A case study on tender evaluation is selected. The system has been implemented by highlighting the role of Guided Ranked Analytic Hierarchy Process (GRAHP) as a systematic and better way to handle the decision making process.
