The world has faced with various environmental problems such as climatic change, global pollution, and depletion of natural resources. Conventional economic development continues not only to intensify the magnitude of the problems but also to damage growth potential of future generations. Therefore, recent manufacturers are highly required to accommodate themselves to sustainable development that aims at preventing the loss to the future generations. Moreover, the manufacturers are under heavy pressure from various environmental regulations. This paper proposes green bill of material (Green-BOM) which conforms to the environmental regulations to restructure eco-friendly manufacturing system. Green-BOM is useful for managing green product and process information to satisfy several environmental regulations by recording energy consumption, recycle rate, volatile organic compounds (VOCs), substance information, and so on.

This paper focuses on a BOM(Bill of Materials) management problem for a small and medium manufacturing company that produce automobile parts. Automobile part's manufacturers produce various products due to various automobile characteristics such as types, colors, and the other options of car. These products are classified into product groups with common parts. And each product group is regarded as a product family. This paper proposes an efficient and effective EXCEL-based BOM management scheme using characteristics of the product family. And we have implemented the practical EXCEL-based BOM management system for real small and medium automobile part's manufacturing companies.

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.

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.

Material Requirement Planning(MRP) has been the most widely implemented large scale production management system in the manufacturing industry. Computerization of MRP systems involves, in general, Bill Of Material(BOM) explosion algolithms which usually takes heavy computation time. In order to improve the effectiveness of the MRP systems, we propose to build a logical BOM database in advance, which reflects the Join operations for the BOM explosion. It reduces the response time for the BOM indented explosion. It reduces the MRP processing time. It also increased main memory utilization.

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.

In this paper we propose an engineering bill of materials (E-BOM) copy method that can be utilized to manage the product information for each equipment during building a product lifecycle management (PLM) system in the order-specific semiconductor equipment manufacturer. The previous works studied on an E-BOM creation and management method for the mass manufacturing and production. The method is difficult to apply to an environment in which many engineering changes occur and the different specification to each equipment is required such as semiconductor equipments and facilities adopting built-to-order instead of built for inventory. Moreover the method is known to be the major drawback to deteriorate the design efficiency. Our E-BOM copy method enables users efficiently to manage the specification of a product and shortens the product development cycle. To implement the E-BOM copy method in the PLM environment, we developed the E-BOM copy system that automatically generates new parts and their numbers according to the numbering rule while copying the E-BOM from existing semiconductor equipments and then can apply the parts for reuse to new semiconductor equipments. This system can duplicate not only 3D CAD data but also technical documents.

The environmental regulation of a product is a global trend. The environmental regulation directives such as RoHS, WEEE, ELV and REACH have impacted Korean export-oriented auto parts manufacturer and affects the export of the product to aboard. In electronics manufacture and auto parts manufacturer, there are different systems for environmental regulation compliance. Nowadays the automotive mechatronics parts in a car are increasing. The HEV and intelligent car will need more mechatronics parts. It is necessary to apply the environmental regulation system of electronics to the automotive parts. In this paper, we proposed the application of PDX standard used in electronic industry to the BOM of the auto parts manufactures and showed an example of generated BOM for selected auto part using PDX. The PDX-based BOM can be used for the recording of environmental substances of the automotive mechatronics part and help the collaboration across auto parts manufactures in accordance with environmental regulation.
