Principles and methods of formulating material consumption quota; To formulate material consumption quota, we must fully mobilize the masses and adopt the method of combining up and down. The quota standard should be advanced and leave room. Forward and backward can be unified. The advanced nature mentioned here is not an unattainable standard, but a relatively advanced standard that most workers can achieve through hard work. If the standard is too high, most people can't reach it through hard work, which will dampen the enthusiasm of the masses. On the other hand, if the standard is set low, many people can achieve it easily, which is not conducive to promoting production and reducing consumption. Therefore, this standard should be ahead of time, and at the same time leave appropriate room, which is the basic principle of formulating consumption quota. Do a good job in the formulation of material consumption quota, and adopt different methods according to the same conditions and small conditions. There are three commonly used methods: technical analysis, statistical analysis and empirical estimation. 1, technical analysis method is a method to analyze and calculate material consumption quota according to design drawings, process specifications, material utilization rate and other relevant technical data. The characteristic of this method is that on the basis of studying and analyzing the reform of product design drawings and production technology, and the possibility of improving the management level of enterprises, according to the relevant technical data, the consumption quota is determined through strict and meticulous calculation. For example, in the mechanical processing industry, the shape, size and material of products are usually analyzed according to product drawings and process documents. Firstly, the net weight is calculated, then the process loss is determined through the technical analysis of each process, and finally the material consumption quota of the product is obtained by adding these two parts. The quota calculated by this method is generally accurate, but the workload is large and technical, and not every enterprise can do it with every material. Because the prerequisite for calculating the consumption quota by technical analysis method is to have relatively complete technical data, and the calculation process is complicated, and the use is limited, it is impossible to require all materials of the enterprise to calculate the consumption quota by this method. For products with large output and complete technical data, technical analysis method should be taken as the main method to formulate consumption quota. With the continuous improvement of the technical management level of enterprises, the application scope of this method will continue to expand. 2. Statistical analysis Statistical analysis is to calculate the average material consumption of a unit product according to the historical data of raw material consumption of a product and the corresponding statistical data of output. On this basis, considering the relevant factors in the planning period, the material consumption quota is determined. The calculation formula is as follows: average material consumption per unit product = total material consumption of products in a certain period/average material consumption calculated by this formula, so we must pay attention to the consistency between total material consumption and product output calculation period. If the calculation period of total material consumption is one year, then the calculation period of product output must also be one year. The average consumption calculated according to the above formula can only be used as consumption quota after necessary adjustment. The adjustment factors in the planning period mainly refer to some factors that can save material consumption through certain technical measures, and these factors should be appropriately adjusted on the basis of the above calculation formula. For example, according to the above formula, the average consumption of material A for producing a certain product is 65,438+00 kg. Considering that a scientific research achievement will be popularized and applied in the planning period, the application of this scientific research achievement can save 65,438+00% of materials, and the consumption quota in the planning period is 9 kg. When using statistical analysis method to formulate consumption quota, in order to obtain the advanced nature of quota, the average advanced number (or advanced average) of actual consumption in the past can usually be used as plan fixed. The average advanced number is to find the average value of each consumption that is more advanced than the total average in a certain period of time. This new average value is the average advanced number. 3, empirical estimation method Empirical estimation method is mainly based on the production experience of production workers, while referring to the material consumption quota of similar products, through the combination of cadres, technicians and workers, to calculate the consumption quota of various materials. Generally speaking, for products with design drawings and process documents, the consumption quota of main raw materials can be calculated by technical analysis, and at the same time, it can be formulated with reference to necessary statistical data and employees' work experience in production practice. Consumption quota of auxiliary materials, fuel, etc. It can be formulated mainly through empirical estimation or statistical analysis. However, no matter what method is adopted, when formulating the consumption quota, we must follow the mass line and implement the combination of cadres, technicians and workers to review and determine the consumption quota of various materials.
