Embodiment 1
[0029] The average protein content of fresh milk purchased by a dairy product manufacturer from October to December 2011 was 3.135g / 100g, 3.093g / 100g, and 3.078g / 100g respectively. A regression model was established based on fuzzy measure and fuzzy integral, and genetic algorithm was used to determine Excavating the patterns and laws in the above data and drawing the data trend curve, it is found that these data show a gradual downward trend, which is inconsistent with the gradual upward trend of the whole province in the same period.
[0030] According to the second rule of the above-mentioned risk warning, "when the key quality and safety indicators of the raw milk or finished products of the enterprise deviate seriously from the general laws of the province, there may be risks such as illegal addition, dilution with water, low-quality raw materials, temporary milk adjustment, and milk grabbing in the early warning." , warn that the enterprise may have the above risks, and re...
Embodiment 2
[0032] In November and December 2011, a dairy product manufacturer purchased raw milk from a dairy household at a price of 2,900 yuan / ton, and the average price of the province in the same period was 3,400 yuan / ton. The model threshold is obtained by point detection, and after the actual comparison, it is found that the deviation reaches 14.7%, exceeding the threshold by 10%.
[0033] According to Article 3 of the above-mentioned risk warning "When the purchase price of raw milk in an enterprise or a certain region is seriously lower than the average market price, there may be risks such as illegal acquisition of low-quality raw materials, illegal addition, and mass epidemics", the company is warned that the above risks may exist, and Report to the relevant administrative department to verify and dispose of the production and operation status of the enterprise one by one.
Embodiment 3
[0035] The "Process Document for Production of Modulated Milk Products" of a dairy product manufacturer requires that the conversion coefficient between raw milk and finished milk be 0.8:1, and the actual purchased raw milk and finished product conversion coefficient is 1.05:1, using clustering algorithms such as k-means and DBScan The threshold of the model was obtained by abnormal point detection. After the actual comparison, it was found that the deviation reached 31.3%, exceeding the threshold by 20%.
[0036] According to Article 7 of the above-mentioned risk warning "When the actual conversion coefficient between the raw material quantity of a single product and the finished product quantity of an enterprise is unstable, there may be risks such as failure to produce according to the process, resale of raw milk, and omission of part of the milk source". The above-mentioned risks shall be reported to the relevant administrative department, and the production and operation s...
