This paper proposed the EGBOM, Extended Generic BOM, which is more flexible BOM system than GBOM. The GBOM system has the limitation to construct Result BOM and to select options by choosing only one Variant under given Cluster. In order to overcome this limitation, we propose the EGBOM which can make more various Result EGBOM, which can use to rolling stock through constructing urban transit BOM using the proposed EGBOM. The last, this paper describes the various Result BOM examples constructed from Source BOM of UT_EGBOM, such as rolling-stock maintenance BOM, individual car BOM, etc.

BOM(Bill of Materials) is a listing or description of raw materials, parts, and assemblies that define a product. In manufacturing companies that produce various products with short life cycles, it is very important to manage the BOM of products with various options and versions efficiently. BOM information should be required to share among the departments of engineering, production control, material purchasing, cost management, and shop floor within a manufacturing company. In order to share BOM information efficiently, information system based on WWW(World Wide Web) should be developed. Thus, this paper models and implements Web-based Generic BOM Management System (WGBMS) for management of a number of variant products which are consisted of standard parts under ATO(Assemble To Order) production environment. Also, object-oriented methodology was used to model a generic BOM and phases of navigational design and interface design were introduced to implement the prototype of WGBMS. And Object-Relational Database Management System (ORDBMS) was used to construct the WGBMS database.

This paper proposes the Advanced Generic BOM(AGBOM) which is more flexible BOM system than existing GBOM. The existing GBOM system has the limitation of Result BOM construction and selecting options by choosing only one Variant under given Cluster. In order to overcome this limitation, AGBOM can make more various Result BOM by selecting several Variants under given Cluster. Also, this paper describes UT-AGBOM which can use to rolling stock through constructing urban transit BOM using the proposed AGBOM. The last, this paper describes the various Result BOM examples constructed from Source BOM of UT-AGBOM, such as rolling-stock maintenance BOM, individual car BOM, etc.

BOM(Bill of Material) is a description of parts, assemblies and raw materials that comprise a product structure. In manufacturing companies that produce various products with short life cycles, it is very important to manage to BOM of products with various options and versions efficiently. This paper describes an effective modeling and implementing technique of Generic BOM Management System(GBMS) for management of number of variant products. In this paper, OMT(Object Modeling Technique) was used to model a generic BOM and Object-Relational Database Management System(ORDBMS) was used to implement the GBMS database. In order to prove the effectiveness of proposed methodology, a case that assembles computer with various options was studied.

Today, customer-requirements are getting various, so manufacturing companies face many problems to reflect them with its' new product development or product variety. As the product model managed by companies is more increasing, there might be much more selection conditions and many kinds of parts requited for it. With those reasons, it demands many different kinds of BOM information for new product development and product variety. Under the those manufacturing environment, we can realize that lots of current products have shared many design property and common parts with those of old version. This thesis present these new products for common characteries are classified design property and common parts with those of old version. with product family and it define with modelling language which is Generic BOM. The suggested prototype programmed with Power Builder 6.0 and Ms-SQL is to help companies manage common parts and develop new product effectively by classifying product family's basic characteries with basic and changable levels.

There are many types of BOM in the industrial world. Types of BOM include EBOM, MBOM, As-Built BOM, As-Designed BOM, Generic BOM, Customized BOM, etc. We should define an adequate BOM for a given need or application. In this paper, we proposed BOM structure for EMU Maintenance Information System. The proposed BOM structure is composed of Location BOM, Equipment BOM, and Maintenance BOM. Location BOM is functional structure for someone to achieve specific works. Equipment BOM is a bill of an independent object to be repaired, and maintained. Maintenance BOM includes all parts to compose Equipment BOM. The BOM structure will be applied to configure sales orders, explode aggregate forecasts, and calculate standard cost.

The BOM(Bill Of Material) contains various important information for establishing production scheduling and purchasing process. For effective and efficient constructing of the BOM, some methods, such as, conventional BOM, Modular BOM and Generic BOM are developed. Many companies input the BOM information with manual process. During this process, no one can avoid human errors, that is input error and to omit input necessary Information. We must to remove the possibility of these human errors, and to construct BOM effectively. To do this, we try to take the BOM from CAD data automatically We have developed a supporting system for extracting BOM from AutoCAD files.

There are many types of BOM, such as EBOM, MBOM, As-Built BOM, As-Designed BOM, Generic BOM, Customized BOM, etc. We should define an adequate BOM to achieve some purposes. In this paper, we proposed BOM structure for EMU Maintenance Information System. First of all, we define Master BOM including all part's information, such as 2D/3D drawings, images, specification, etc. And then we define Object BOM that is functional structure for someone to achieve maintenance works. Object BOM will be applied to configure sales orders, explode aggregate forecasts, and calculate standard cost.
