BOM in enterprise creation

What is Bom? To use computers to assist enterprise production management, computers should first be able to read the product components and all materials to be involved in the enterprise. In order to facilitate computer identification, the product structure expressed in the figure must be converted into a data format. The document describing the product structure in the data format is the BOM. It is a technical document defining the product structure. Therefore, it is also called a product structure table or product structure tree. In some industrial fields, they may be referred to as "recipes", "element tables", or other names. In mrp ii and ERP systems, materials have a wide range of meanings. They are all products, semi-finished products, in-process products, raw materials, accessories, and collaborative parts, consumable products and other materials related to production. In general mrp ii and ERP systems, BOM refers to the relationship tree composed of parents and child parts. BOM can be in the form of top-down decomposition or providing information in the form of bottom-up tracing. In the mrp ii and ERP systems, Bom is an organizational relationship between data. The hierarchical relationship between these data can be used as the basis for designing many functional modules, some forms of this data are summarized reports that we are all familiar. What is the function of Bom? Bom is the most important basic data in PDM, mrp ii, and ERP information systems. Its organizational format design and rationality directly affect the processing performance of the system. Therefore, according to the actual use environment, it is very important to flexibly design a reasonable and effective Bom. Bom is not only an important input data in the mrp ii system, but also an important basis for the Financial Department to calculate costs and the manufacturing department to organize production. Therefore, BOM has the largest impact, it has the highest accuracy requirement. Correct Use and Maintenance of BOM is an important task during the operation of the management system. In addition, Bom is an important interface between CIMS/MIS/MRP ⅱ/ERP and subsystems such as CAD and CAPP, and is the key to system integration. Therefore, when BOM management is implemented by a computer, it should be fully considered in the information exchange issue of other subsystems. BOM information is used in the mrp ii/ERP System for MRP calculation, cost calculation, and inventory management. BOM has various forms, which depend on its purpose. Bom has specific purposes: 1. It is the basis for computer identification of materials. 2. It is the basis for preparing the plan. 3. It is the basis for supporting and collecting materials. 4. Track the processing process based on it. 5. It is the basis for procurement and outsourcing. 6. Calculate the cost based on it. 7. The quotation can be used as a reference. 8. Perform material tracing. 9. serialization, standardization, and generalization of the design. What are the BOM forms? Product Division by purpose should go through three stages: engineering design, process manufacturing design, and manufacturing, in these three processes, the EBOM, PBOM, and cbom of materials with similar names but different content are generated respectively. These are three main BOM concepts. Engineering BOM--EBOM (Engineering BOM): The data structure used in product engineering design management. It usually accurately describes the design indicators of the product and the design relationship between parts. The corresponding file formats mainly include product details, drawing directories, material quota details, and various product categories. Planning BOM--PBOM (Plan BOM): The EBOM is designed by the process engineer Based on the processing level and capability of the factory. It is used for process design and manufacturing management. It can be used to clearly understand the manufacturing relationship between parts and tracking how parts are manufactured, where to make, who to make, what to use and other information. PBOM is also one of the key management data structures of mrp ii/ERP production management. In fact, Bom is a broad concept. Based on different purposes, BOM has many types. Bom on the design drawing paper, Plan BOM, calculate the Manufacturing BOM of the final product assembly, and calculate the cost BOM of the cost, maintenance and Repair Bom. According to different stages of different application focus, we often see different BOM formulation, common are: Design BOM--DBOM (design BOM): Design Department dbom is the overall product information, common text formats include product details, drawing directories, and material quota details. The source of design BOM information is generally the title bar and Detail Bar information in the complete set of design drawings provided by the design department. Sometimes it also involves some information on the process card prepared by the Process Department. The design Bom is generally generated at the end of the design. If there is a large number of borrow relationships, the design BOM can be summarized at the beginning of the design phase, then, design tasks based on the newly generated parts. The corresponding electronic view is often in the form of a product structure tree. each node in the tree is associated with various attributes or graphic information. Mainly used in PDM software as basic data for product management and Image File Management
