Popis:	This paper analyses the existing productivity measurement system for shipbuilding and brings out the gaps in the present system. In shipbuilding, often partial productivity is measured, due to the difficulties associated with calculating total productivity. Measurement of total productivity requires computation of multifactor efficiency and this can be evaluated using Data Envelopment Analysis (DEA), which is a mathematical linear programming technique. The need to measure multifactor efficiency for shipbuilding has been investigated in this paper. It is proposed that efficiency estimation using DEA by considering Compensated Gross Tonnage (CGT) of ships along with the shipbuilding effort using Work Breakdown Structure (WBS) would be a scientific method for measuring shipbuilding productivity.
