Car manufacturing BOM management method and management system

Abstract

The invention discloses a car manufacturing BOM management method and management system. The management system comprises a low-order BOM updating unit, a high-order BOM generation unit, a first layer part list calculation unit and superposition unit, a difference quantity calculation unit, a single car low-order BOM updating unit and a car manufacturing BOM generation unit. The method includes the steps that a PDM system sends variable quantity of information of a low-order BOM to an ERP system; the ERP system generates a high-order BOM and sends the high-order BOM to the PDM system; the PDM system determines first layer part lists of all unfolding vehicle models; the PDM system determines a single car lower-order BOM; the PDM system calculates difference quantity between the last single car lower-order BOM and the current single car lower-order BOM and sends the difference quantity to the ERP system; the ERP system updates single car lower-order BOMs stored in the ERP system according to the difference quantity; when car manufacturing BOM request information is received, the ERP system generates a car complete manufacturing BOM. The BOM is managed and manufactured on the basis of a platform, and repeated operation is reduced.

Description

technical field [0001] The present invention relates to a bill of material (BOM), and more specifically, relates to a management method and a management system of a vehicle manufacturing BOM. Background technique [0002] The traditional automobile manufacturing industry is a production mode with few varieties and large batches, that is, a large-scale production mode. In this production mode, the management concept of single-vehicle BOM is usually adopted, and Excel is simply used for BOM management, that is, It is said that the traditional technology needs to manage the BOM of each bicycle. However, with the increase of customers' individualized demand for locomotives, the current locomotive manufacturing industry has gradually changed from a large-scale production model to a mass customization production model. In addition, the vehicle models are becoming more and more diverse, resulting in a sharp increase in the number of BOMs formulated and maintained. The huge BOM dat...

However, with the increase of customers' individualized demand for locomotives, the current locomotive manufacturing industry has gradually changed from a large-scale production model to a mass customization production model. In addition, the vehicle models are becoming more and more diverse, resulting in a sharp increase in the number of BOMs formulated and maintained. growth, and the huge BOM data has brought enormous pressure to the traditional bicycle BOM management concept and the way of simply using Excel to manage

[0003] For example, when it comes to the change of a certain part, if the part is used by many vehicles, it is necessary to modify the BOM of all the single vehicles using this part one by one, which will lead to a huge workload and will undoubtedly seriously affect the enterprise work efficiency, and greatly increase the possibility of errors
