  • 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.

  • 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.

  • A study was conducted to improve validity in new BOM structure through using the similitude of existing BOM in the PDM. The system is developed in Web-Based PDM environments using servlets and database. The system provides the correlation information between parts to inflect the reusability of existing BOM. User-defined correlation is used to inform the relations between design precedence and co-relations of parameters. Realistic application in injection mold production is constructed using this structure.

  • Both enterprise information systems and CAD utilizes the BOM (Bill of Material) as the means of collaborative integration during the product design and production since the BOM has been commonly used for design, production planning, procurement, and production works. Therefore, BOM can be the referential data when it expresses not only the part lists but also product information required by product development process. Outfitting design is one of major design works in marine vessel design since marine vessels have various outfitting systems and huge number of parts. Also, the outfitting BOM has the evolutional forms that change from the initial design to the production design. In order to express the product information and part list in the enterprise BOM and the evolutional BOMs in each lifecycle, enterprise BOM of outfitting that consists of structure BOM and display BOM is suggested. Thereafter, we have developed the prototype of enterprise BOM in which some features of the outfitting BOM are implemented.

  • 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.

  • 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.

  • 소비자의 요구가 다양해지면서 많은 기업들이 관리해야 할 제품의 종류가 지난 몇 년간 급격히 늘어났다. 이에 한 제품에 대해 다양한 품목군을 유지해야 할 필요성이 제기되었으며, 전통적인 BOM(Bill of Material)으로 다양한 제품을 표현하기에는 막대한 양의 데이터가 발생하여 관리상의 어려움이 생기며, 데이터의 구성에도 중복성의 문제가 발생하게 되는 등의 한계가 드러남에 따라 다양한 제품군을 자체적으로 반영할 수 있는 Variant BOM의 개념 및 설계 방법론이 주목을 받고 있다. Variant BOM은 동일한 제품군에 대해 일부 구성품을 달리하여 구현한 다양한 제품을 반영하는 BOM의 한 종류로서 산업에서의 활용도가 높은 편이나, 여기에도 데이터의 중복성이나 Variant의 정도가 많아지면 관리에 어려움이 생기는 등의 몇 가지 단점을 내포하고 있다. 본 연구에서는 Variant Bill of Material을 대상으로 기존 연구들의 문제점을 분석하고 이를 해결하기 위하여 BOM에 좌표개념을 도입한 새로운 접근법을 제시한다. 이를 통해 BOM의 Structure와 Part를 분리시켰고, Linking Table을 통해 Structure와 Part를 연결하여 기존의 Variant BOM에 있던 문제들을 해결하였다.

  • As a product structure or BOM(bill of material) of products is hierarchically structured, the design based on the concept of relational data base modeling causes low performances in data search or processing. For this reason, an object-oriented approach to designing a product structure is proposed in this paper. Using Rumbaugh's OMT (Object Modeling Technique) method, classes of parts, BOM structure, options, and models are defined and their class-relationship diagrams are proposed. For the representation of the BOM structure suitable for the object-oriented paradigm, a new data architecture called the BOM item class is suggested. It is expected that the proposed data structure ensures better reusability and expandability due to the modularity.

  • Purpose: For effective quality assurance activities, BOM-based quality assurance method is presented. This study introduces various BOM conversions such as Q-BOM, T-BOM, and S-BOM based on M-BOM structure. Methods: Product quality control via Q-BOM manages inspection/audit information, overall supply-chain of product, part requirements, and inventory status. T-BOM manages part traceability, and S-BOM enables statistical control over key process and parts at various hierarchy levels. Results: Quality plan template was developed based on the study results of BOM system including Q-BOM, T-BOM, and S-BOM. Conclusion: Through BOM(Q-BOM, T-BOM, and S-BOM) study and development of quality plan template, more systematic and comprehensive quality management plan is achieved.

  • Two key data areas of the integrated production database in computer-integrated manufacturing (CIM) systems are the product structure in the forms of bills of material(BOM) and the process structure in the forms of routings. The great majority of existing information systems regard the BOM and routing as two separate data entities, possibly with some degree of cross-referencing. This paper proposes new information structure called the bills of material and routings(BMR) that logically integrates the BOM and routings for the CIM systems in ship production. The characteristics of ship production are described as: 1) make-to-order production type, 2) combined manufacturing principles (workshop production and construction site production), 3) significant overlapping of design, planning and manufacturing, 4) very long order throughput time, 5) complex product structure and production process. The proposed BMR systematically manages ail parts and operations data needed ship production considering characteristics of ship production. Also, the BMR situated on the integrated production database more efficiently supports interface between engineering and production functions, and integrates a wide variety of functions within production such as production planning, process planning, operation scheduling, material planning, costing etc., and simplifies information flow between sub-systems in CIM systems.
