In this embodiment, the cancellation value refers to the cancellation on the progress, that is, if the progress of the actual achievement 1 is identical to or equal to the progress of the standard achievement 1, the cancellation value is 1, otherwise, the smaller than 1, the greater the progress difference between the two is, the corresponding cancellation value tends to 0, and the value of the first preset threshold is generally 0.5.
In this embodiment, the outcome weights are preset.
