In order to meet the needs of manufacturing enterprises in materials management, improve the market competitiveness of enterprises, and realize the scientific management of modern enterprise, intelligent manufacturing engineering management system based on bill of material (BOM) was developed and designed. In this study, the concept and role of BOM are described in detail, the theory of intelligent manufacturing theory is explained, and the BOM classification method is introduced. In addition, a new BOM coding standard and method is applied to the original BOM code. This technology introduces the processing technology into the code, which effectively improves the readability of the code and solves the old garbled phenomenon. At the same time, an improved BOM quality tracking model was proposed. In this model, quality tracking of the whole process is implemented. The model can determine the origin of quality in the aspects of processing technology, processing workshop, production batch, purchasing batch, material supplier and so on, so as to provide reference for solving the problem.
