Application of Modern Work Breakdown Structure in Shipbuilding Procedure

With the development of shipbuilding technology and the presentation of the concepts of zone construction, interim product and Integrated Hull construction, Outfitting and Painting (IHOP), traditional Ship Work Breakdown Structrue (SWBS) is unsuitable for existing shipbuilding procedure. By studying shipbuilding procedure in several shipyards in China, this paper gives a new SWBS and presents a three dimensional model of Modern Ship Work Breakdown Structure (MSWBS), which integrates process structure, organization structure and product structure in shipbuilding procedure. This model solves the shortage of traditional SWBS that cannot dynamically show shipbuilding procedure. And then this paper discusses the application of MSWBS in three aspects. The first is code design of MSWBS, which consists of the subcode of process structure, the subcode of organizsation structure and the subcode of product structure. The second is design of a data structure model based on MSWBS. The model includes twentyt one data records which are correlative with each shipbuliding cell broken down by MSWBS. As an information exchange platform between departments in shipyard, this model can realize the share of all kinds of data between design department, production planning department, cost management department, supply department and so on in the complete period of shipbuilding. And it brings real time monitor into effect in shipbuilding procedure through trigger mechanism of MSWBS database. The third is risk management in shipbuilding procedure based on risk identification. By applying the MSWBS all kinds of risks can be identified efficiently in shipbuilding procedure. So some strategies can be applied based on the identified risks to reduce losses
