loping ways on how to reconstruct the entire workflow then improve the performance, and even attempted to set up its own ERP system. In this system the production information within the outfitting management system is anticipated to be able to handle advanced designing stage in which design and production can access the same database. For finding the solution, in 2001, the system set of SCM was developed to transact with the upstream longterm suppliers。 meanwhile concluding the XML DTD standard, the system enable to directly exchange ponent data and access each other39。s database, even integrate the suppliers39。 ERP system (Fig. 5).

Procurements of orders (POS) should be original from a thorough bill of material (BOM), with the bids for the materials before production stage。 however in actual procurement process most of POS are executed very often earlier than BOM generated because of tight scheduling. The major portion of present material operations in CSBC39。s design department depends on construction data of sister ships or other foreign shipyards39。 built ships etc. to estimate the required amounts of outfitting and then to be the practical statistic material information. Because the estimation of the great amounts of outfitting by people is a minute and plicated work, and the production information from the upstream design to downstream procurement is not integrated yet, it usually directly impacts the count management in the construction unit, and obstructs the achieved percentage of scheduled progress. The objective to construct a businesstobusiness (B2B) SCM system is to assist CSBC using electronic ways to transfer inefficient procurement, inextricable process and unmethodical searching into a high performance electronic procuring process (Fig. 6). To improve the transmission efficiency of altered information and design drawings in the traditional outfitting supply chain, the system is anticipated to be more capable of control of the schedules and progress of production of suppliers, and enable the longterm suppliers to coordinate with the ship building progress, not to postpone the production schedule. SUPPORT IN ACCESSING DATA Via reconstructing the rationalized and standardized work process, to let the operation of the production control be advanced toward the design stage is anticipated. Tools for support in accessing data have to enable directly access 3D modeling. Data in the Tribon production information model (PIM) are accessible via the Data Extraction facilities [2], which is able to retrieve specific information from one or several objects by specifying the type and name of the model object and the wanted item within the object. Further, the data extracted form production model database generated by design department can be integrated with SCMs, and spontaneously update the production information in Management Information System (MIS). Comprising the Data Extraction objects, Vitesse is a major module of Tribon Developer39。s Toolkit, which is used by customers to develop additional functions, . automation of modeling and drafting tasks, data exchange and system integration with project data management systems on an enterprise level. The extracted data is directly imported into SQL and Oracle databases, or through data postprocess generate designated reports. After the plicated customized data extraction from PIM, the partial material data sourcing for POS can be generated. However, there is still one portion of material data also extracted from PDMS by Programming Macro Language, more monly called PML. REQUIREMENT ANALYSIS 1. Detail Analysis Detail analysis is to search and collect the relevant information of this system carefully, and then the real requirements for this system can be known and given clear definitions. After detail analysis it39。s easy to understand what the requirements are, and further consider the feature of ship building39。s SCM. 2. Preliminary Analysis By preliminary analysis to grasp the purposes, functionalities, limit conditions, main request information, workflow etc. of the entire system, the descriptions are as POS Agreement circulationdelivery accounts payable receiving route to recipient Bid inquiry announcements/QuotationSCM system Agreement Orders. Shaw, W. Tann and . Chuang: The Establishment of the Supply Chain Management System for the Bigsized Shipyard 174 follows: Purpose: Off ering outfitting with the right quality and quantity through JIT (Just In Time), and saving the time to municate and pursue materials, promoting the performance and reducing the production costs. Functionality: Offering a clear management for contracts, inventories, goods received, queryinformation, and accounts of suppliers etc.. Requirements: Via the system to query the order states and goods received, CSBC can know the information of relevant suppliers and maintain the account information。 suppliers can check order status, received goods, accounts, and maintain their own information. Both can transmit information mutually (Fig. 7). Fig. 7 The system architecture. Fig. 8 The unrolled system functionalities.
