Because of time constraints, as a matter of fact, design decisions are made fast and in a reactive way, according to the particular case, without considering decisions made in the past and without using specific decision support tools. The final choice is often left to a single designer's experience, whose selection criteria are unknown and not formalised. As a consequence there is no shared knowledge justifying the reason why a design solution has been chosen and whether it is the best one. We developed and implemented in Fincantieri S.p.A. – a leading company in the cruise ship industry – an original decision support tool, based on value analysis, designers can use to document and formalise their choices. Value analysis is a well known structured method to increase product value and/or cut costs, thus supporting the selection of the most valuable solution by means of objective parameters. We demonstrate that the proposed tool can also facilitate reuse of the available knowledge base on decisional criteria, increase interactions between people (design staff, buyers, shipyard personnel, etc.) involved in different stages of different value analysis projects, and reduce decision time.

MEASURING PRODUCTIVITY IN THE U.S. SHIPBUILDING INDUSTRY

India has labour cost advantage. . The labour cost per worker in India is
estimated at $1,192 per year, against $10,743 and $21,317 per worker in 2007 in South Korea and Singapore. . Labour cost is a key factor in shipbuilding nations as it accounts for more than 10% of the total costs. China also has considerably lower labor costs as compared to competing countries. (Around 50% of Korea and Japan).
A shipyard typically requires a working capital of around 25-35% of the cost of the ship during the entire construction period.
Indian yards lack the capability to build large and modern ships. Presently, the Cochin shipyard is the
only one that has the capability to build large and modern ships. Hence shipbuilding in India lacks
infrastructure support which reduces the capacity of production.
