船舶建造的现代工程分解结构

Application of Modern Work Breakdown Structure in Shipbuilding Procedure

针对船舶建造项目 ,通过分析传统的工程分解结构 ,提出一种现代的船舶工程分解结构 (Modern ShipWork Breakdown Structure,MSWBS) ,解决传统工程分解结构方法不能动态地反映船舶建造过程的不足 ,并探讨 MSWBS的代码设计及以 MSWBS为基础建立一种公共的数据结构模型 ,以实现船舶建造企业各部门信息的共享。这种工程分解的思想对于类似船舶建造的复杂大型项目也适用。

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
