[Abstract]:Food safety inspection, apple export grade inspection and evaluation, product quality control on Chinese production line, product quality control and inspection in supply chain, customs and commodity inspection bureau and so on, have many demands in the application of quality multi-grade sampling.International and national sampling standards also need to be supported by perfect theories and methods.The multi-grade sampling scheme has a stronger ability to identify qualified and unqualified batches, brings more economical inspection to quality control, and provides a favorable tool for the implementers of quality control and continuous improvement.Therefore, this paper studies the theory and method of three-grade product counting in theory and method.First of all, on the basis of classical two-level counting sampling, aiming at the problem that the existing three-grade product counting one-time sampling scheme is relatively simple and unable to cover the actual more demand, six three-grade product counting one-time sampling schemes are proposed.The sampling characteristic function of these sampling schemes is given, and an important concept of "equivalent number of unqualified products" is put forward.At the same time, the geometric representation method of the sampling scheme is established, and the new and old sampling schemes are studied and compared with the graphic method. Based on this, the general influencing factors and the suggestions on how to select the sampling scheme are given.Secondly, the design criterion of the sampling scheme is established, and the design method suitable for the general sampling scheme is given.On the basis of sampling scheme, this paper summarizes the properties of OC function of three-grade product counting sampling scheme, decomposes OC surface into many curves, and puts forward the idea of designing sampling scheme with the help of some important points on 1 2p?p plane.The design criteria of three-grade product count-one-time sampling scheme are established.At the same time, a general method of designing a sampling scheme for three-grade products is given, and an optimized model is established. Based on the results of numerical examples, the proposed design method is further supplemented and explained.Thirdly, based on the theory and method of classical counting quadratic sampling, this paper studies the three grade product counting quadratic sampling.In this paper, a three-grade product counting quadratic sampling scheme is proposed, the inspection process is given, the batch acceptance probability is calculated, the OC function is derived, and the 3D OC surface and contour are given according to the function.The formulas of mean sample size for the second sampling are derived, and the 3D ASN surfaces and extreme points are given, and the influence of the parameters of the sampling scheme on the ASN surfaces is analyzed.Finally, the design method and the model algorithm of the three-level counting quadratic sampling scheme are given, and the comparison between the three-grade counting one sampling scheme and the second sampling scheme is given, and the conclusion that the quadratic sampling scheme has more economical advantages is obtained.Based on the results of numerical examples, the correctness and availability of the above theory are further verified.Finally, taking the hub products of Linhai Jufeng Machinery Co., Ltd as an example, applying the theory and method of counting and sampling the three-grade quality products proposed in this paper, combined with the characteristics of the products,The selection and design of the sampling scheme and the selection and design of the second sampling plan are carried out respectively for the inspection of its ex-factory products, and the sampling scheme suitable for Linhai Jufeng Machinery Co., Ltd is selected according to the comprehensive consideration.This is how to apply the three-class product count sampling theory and method to play a role in demonstration.
