[0070] Please refer to Figure 2 , obtain the process conditions configured by the user, and screen out the corresponding project phases and link processes from the template library; obtain the parallel relationship of the current link process, if there is no parallel link process for the current link process, then the estimated end time of the current link process is f(y i ) = f(x i ) + T i ; the estimated start time f(x i+1 ) of the next link process = f(y i ); among them, f(x i ) is the estimated start time of the current link process, f(y i ) is the estimated end time of the current link process; T i is the committed duration of the current link process;

[0071] If the current link process has parallel link processes and the parallel relationship is AND, then the estimated start time of the next link is f(x i+1 ) = max[f(y i ), f(y m ), … f(y k); where f(y i ), f(y m ), … f(y k ) are the current process and the processes parallel to the current process;

[0076] For example: Suppose analyze the longest promised durations of 3 process flows in project 1, and obtain the longest promised duration of process flow 1 as 37 days, the longest promised duration of process flow 2 as 33 days, and the longest promised duration of process flow 3 as 56 days through the formula.

When R(i - 1) > 0 and R(i) ≤ 0, the corresponding Xi For the planned process flow and calculate X i position.

[0089] For example: Suppose there are 4 process flows in the existing project 3, and the longest committed times of the 4 process flows are 10 days, 20 days, 30 days, and 15 days respectively; the current process flow is 3 and it has been carried out for 15 days. Calculate that the sum of the longest committed durations is 45 days. By calculation, the project usage duration is 28 days, then the difference d = 17.
