Core Difference Implementation Path
Take the optimization process of a cashmere group as an example: by applying formula (9), the accuracy of commercial net wool rate ±0.8% is improved, and the detection time is shortened by 58% by using distributed computing methods…
Detailed explanation of the new calculation model
Commercial net wool rate (Y) = ∑(Y_i*M_i)/M
The calculation formula of the cross-linking factor Bi is updated synchronously: $$B_i = \frac{W_i(1-γ_i)}{ΣM_j}$$, realizing intelligent calculation of pollutant compensation
