Description

Technical field:

[0001] The invention relates to a special BOM management system for a wind turbine cabin cover. Background technology:

[0002] BOM, or physical inventory, is a technical document that describes the composition of a company's products. It is used to record the components required for a product and is of great significance for early cost management. However, in the wind turbine nacelle industry, the inevitable program changes, uncertainties, and repetitiveness of new projects make BOM construction and cost tracking more difficult, and a large amount of resource investment cannot guarantee timeliness and accuracy.

[0003] At present, the existing BOM management system for wind turbine nacelles is relatively simple, with single overall functionality. It can only be applied to material procurement and material collection, fails to provide relevant guidance for other departments, is prone to large deviations, and cannot provide data standards and management basis for project management. The hierarchical structure is difficult to build, which makes it not fully applicable to the wind turbine nacelle industry. Summary of the invention:

[0004] The embodiment of the present invention provides a special BOM management system for wind turbine nacelles. It has a reasonable structural design, integrates multiple systems and multiple departments based on the mutual cooperation of multiple functional modules, and can be applied to different scenarios such as new project quotation, process guidance, material procurement, material collection management, material management and working time management. It improves the overall functionality of the system, reduces the errors generated in the production management process, provides accurate data standards and management basis for project management, and uniformly regulates and controls multiple systems and departments, solving the problems existing in the prior art.
