Abstract: With the merger of Baosteel and WISCO,the varieties of grain-oriented silicon steels in the two production bases of Baoshan and Qingshan have been integrated. In order to further give full play to the scale benefit, improve the production efficiency and improve the competitiveness of enterprises, the standardization and feasibility analysis of the mechanism were carried out for the important link of production and marketing collaboration. On the premise of establishing and implementing the unified product enterprise standard, the quantitative decision-making method of production and marketing collaboration was discussed, which transformed the actual business problem into a mathematical programming model and obtained the optimized order receiving and material feeding suggestions by solving the model. It provided a theoretical basis for balance between the production side and the sales side, so as to maximize the effects of "scale", "benefit" and "efficiency".

Key words: production and marketing collaboration, efficiency, silicon steel
