Losses caused by the formation of manufacturing defects and by-products can be a significant share in the cost structure when creating goods. It seems logical to try to take into account the amount of scrap and by-products in the planned costs of material resources, to include these values in the system of technical and economic indicators. This material is devoted to the issue of improving the algorithms for calculating the consumption rates of material resources, coordinating the process of planning marriage and by-products and developing standards for resource costs. The material examines the pool of publications on this topic. The basic elements of mathematical algorithms for calculating the planned consumption of material resources, as well as resource rationing algorithms that integrate product quality indicators are given. It is pointed out to a certain collision that occurs during integration, to a discrepancy with methodological principles. The author's approach to the harmonization of these systems within the framework of the mathematical model of resource rationing is given.
