In specific implementation, whether each screened program passes the manual review can be further determined, if not, a manual review task is generated, and the starting time window (T3-T4) of the task is to be calculated.
And S103, determining the task time and the latest starting time point of the head and tail examination task and the manual examination task of each program material according to the broadcasting time and the broadcasting time of each program.
In specific implementation, the time length of each head and tail trial task is calculated (L1), and the calculation method may be as follows: reading the configuration of a head-tail inspection task system (head-tail inspection software), and acquiring the head inspection time Y1, the middle inspection time Y2 and the tail inspection time Y3 of the material; judging whether the program broadcasting time length X2 is greater than Y1+ Y2+ Y3, if so, judging that the head and tail inspection task time length L1= Y1+ Y2+ Y3; if the program-airing time length X2 is less than or equal to Y1+ Y2+ Y3, the head-to-tail trial time length L1= X2.
The duration of each manual review task is calculated (L2), which may be as follows: according to business requirements, if the material playing time length is greater than or equal to the specified time length Y4, the manual review task time length L2= the material playing length (X2)/the material review double speed (N1), otherwise L2= X2.

In specific implementation, after the calculation is completed, the time window of each task may be checked to determine whether the left boundary of the task window is smaller than the latest starting time point of the task (Z1 or Z2).
In specific implementation, after the verification is completed, the tasks can be optimized and reordered, and the tasks of the same type are ranked in adjacent time periods as much as possible.
Specifically, the following method may be employed:
A. browsing backwards from the first task according to task sequencing to find two tasks (task X and task Y) with inconsistent task types before and after the first group;
B. according to the types of the two tasks X, searching a first other task of the same type backwards, and if the first other task cannot be found, ending the step; if the same type of task C can be found (the previous task of the task C is a task D), trying to insert the task C after the task A;
C. after the reordering is completed, recalculating the time window of each task from task C to task D; after the time window of each task is calculated, whether the left boundary of the task is smaller than the latest starting time point of the task is judged (Z1 or Z2), if the left boundary of the task is smaller than or equal to the latest starting time point of the task, the time window of the following task is continuously calculated until the new time window of the task D is calculated, if the left boundary of the time window of a certain task is larger than the latest starting time point of the task (Z1 or Z2), the change generated by the operation B, C of the current round is cancelled, and the step C is ended;
D. starting from the task D, continuously searching a first group of tasks with different task types backwards, and if the first group of tasks cannot be found, ending; if so, B, C, D is repeated.
In specific implementation, the right boundary time of the task window of the last task may also be obtained as the left boundary T5 of the test channel drill time window, and the right boundary T6 of the channel drill window is the current time +24 hours of the system.
