Blending technologies are important in many sectors of industry, but are most prevalent in the chemical and food industries. They are playing an increasingly important role in the world economy despite the spread of electromobility. Nowadays, in addition to the technological aspects, there is a growing need to look at the logistical aspects, as logistics related costs account for a significant part of the cost of blending technologies. In this research work, the results of the analysis of the impact of quantity discounts, an important aspect of procurement activities related to blending technologies, are presented. A mathematical model is presented that can be used to investigate the impact of quantity discounts of components on profit and product quality. Based on scenario analyses carried out based on the mathematical model, it is demonstrated that the quantity discount can have a significant impact not only on total cost and profit, but also on the quality of the finished blended product.
