BOM(Bill of Materials) is a listing or description of raw materials, parts, and assemblies that define a product. In order to evaluate the performance of proposed BOM management system, which is very important to maintenance information system of urban transit. We develop component based BOM data and rule-set to design data structure that is mutually independent and integrated efficiently. It divides data whit management interface using component technology. The component based master BOM have advantage in database size and flexibility. Flexibility is measured as the number of updating records in accordance with added new product or engineering change. In database size, component based BOM is the best. we develop master BOM management system in web environment.

In accordance with the trend for cooperation of related company, BOM (Bill of Materials) has become an important factor in the manufacturing of production. BOM manages a various basic information of design, production, and process and so on. Especially, automobile industries are related to many company, they build a cooperative system from the communication of information. In this study, we have analyzed a BOM structure of a well-used automobile part industry and proposed a structure of engineering BOM, manufacturing BOM, process BOM for cooperative environment. A proposed various BOM structure are flexible in responding to the situation of structure alternations for automobile part. And also they include in environment factors. It is expected that these BOM structure will be used to basic template in automobile part industry which could be loaded with cooperative hub-system.

The most important part of RIMS(Rolling Stock Information Maintenance System) project is to construct BOM(Bill of Material). BOM is a listing or description of raw materials, parts, and assemblies that define a product. To construct BOM for RIMS is not a easy task due to several reasons such as data base scale and flexibility, proper integration between physical BOM and functional BOM, interoperability with other systems, etc. In this study we show several principles that Seoul Metro takes to get over the difficulties mentioned above. Based on these principles we propose the methodology Seoul Metro employs to construct BOM efficiently. We also discuss the applicability of BOM in several fields.

BOM(Bill of Materials) is a list or description of raw materials, parts and assemblies that define a product. Although it is very important for maintenance information system of urban transit, it has problems that the size of database, inaccuracy and the flexibility which is measured as the number of updating records in accordance with added new product or engineering change. To solve these, we divide BOM to a master BOM and various function BOM constructed from the master BOM. That is the component based BOM management system, which is mutually independent and integrated efficiently using component technology. Consequently, after defining the component based master BOM, it is easy to manage the data structure, even restruct, in case there is a need for change of environment or data.

Bill Of Materials(BOM) is the technique document on illuminating the product structure and used to demonstrate the relationship and structure between the final product, sub-products, parts and materials. This paper implemented BOM system for need parts production that is need in production of finished goods that is display stand that is made by steel. After implementation the BOM system, there are changing of the corporation, which applied this system: (1) contraction by 2 weeks to 2 days of the time to calculate parts required for products (2) accuracy improvement of calculation for amounts parts required (3) contraction of business organization.

Generally, BOM (Bill of Material) means a part list which is needed to manufacture or assemble a product or part. During manufacturing processes, BOM is inevitably required for most of enterprise processes such as design, procurement, production planning/control, resource planning, and financial works. Every manufacturing industry uses many kinds of BOM's that are adjusted to the requirement of functions of their work division. Moreover, BOM evolves in different forms according to the product development phases such as conceptual design; function design, detail design, and production design because it is necessary to use different product structures to keep product data generated throughout the lifecycle of a product. This includes all data and information related to the all the product development phases. Shipbuilding works also are processed and controlled based on BOM. However, effective maintenance of ship outfitting BOM data is getting difficult as the amount and complexity of data have increased due to variety and long lifecycle of ship. For the effective management of outfitting BOM data, two aspects must be considered. One is how to classify numerous BOMs type and the others how to display BOMs. So this study suggests a method to classify BOM types and propose two categories - Structure BOM, Display BOM. Base on this result, we propose the integrated ship outfitting BOMs model and analysis outfitting BOMs.

수주생산환경에서는 고객과의 주문 상담과정에서 여러 가지 정보(가격, 인도기간, 기호, 제품사양 등등)를 파악해야 된다. 본 연구에서는 고객의 요구에 부합하며, 최적의 제품구조를 가지는 우연한 BOM 시스템을 구성하고자 한다. 이러한 유연한 BOM 시스템을 위하여, 제공되는 정보를 분석할 수 있는 수리적 모형을 제시하고, 이를 객체지향적 패러다임을 이용하여 BOM 시스템 요소들을 UML로 구현한다. 또한, 이러한 연구의 결과를 바탕으로 주문형 컴퓨터를 위한 BOM 시스템을 실제로 구현한다.

The primary role of MRP(Material Requirement Planning) is to make a production plan so that we have an exact quantity of right materials on needed time at right place. But the ignorance on capacity constraints makes some problems whenever production schedule is established. To increase the performance of MRP system, a novel approach which is based on new input data structure is suggested. The new input data structure includes all the information about Material BOM, Routing and resource data so that we can easily examine the usage of resources and generate higher performance production plans.

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.
