Index Terms: Global market regional of BulkCarrier shipbuilding group decision-making; Consensus; interval fuzzy preference relation.



Abstract: The BulkCarrier shipbuilding industry is marked by its global presence with ships being built in industrialized countries such as Japan, Europe, South Korea and China. The geographical distribution of new ship construction has show strong change starting from the original dominance of Europe to an increased role for Asian countries such as South Korea, Japan and China. The decision makers for strategic purchasing of marine companies greatly require an efficient, valid and fair tool to assist them in determining appropriate region to build from, which belongs to multi criteria Decision-Making problem. Most methodologies that deals with multi criteria Decision-Making even it deals with uncertainty problem need database to deal with the certainty portion, and it needs experts for more than one stage to give their opinions. In this paper, we present a consensus model for Group Decision-Making GDM problem with interval fuzzy preference relations to assist the decision maker to take the appropriate decision in short time under upset of data. We introduce an application example in choosing the best regional distribution of ship building market. The input data for this model were collected from expert persons, and the output is ranking of BulkCarrier shipbuilding region. The final rank of BulkCarrier shipbuilding region in year 2013 is China at the first then Europe , Japan and South Korea comes at the end.
