The obtained associated production information is that the ratio of 9: 00-10: 00, a certain production device automatically produces 25 finished refrigerator products, and 20 finished refrigerator products are manually packaged, so that the obtained deviation information is that 5 products are produced less for a certain production device, and 10 products are manually packaged less.
