[0070] See also Figure 2 , obtain the process conditions configured by the user, and filter out the corresponding project stages and link processes from the template library according to the process conditions; obtain the parallel relationship of the current link process. If there is no parallel link process in the current link process, the estimated end time of the current link process is f(y i )=f(x i )+T i ; The estimated start time of the next process f(x i+1 )=f(y i ), where f(x i ) is the estimated start time of the current process, f(y i ) is the estimated end time of the current process; T i The committed duration of the current process;

[0071] If the current link process has a parallel link process 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 ) is the current link process and the link process parallel to the current link process;

[0073] For example: Assume that there are three process steps in the existing project 1; analyze the estimated time of the three process steps; process step 1 and process step 2 are parallel processes, and the parallel relationship is and; the estimated end time of process step 1 is May 27, and the estimated end time of process step 2 is May 21; then the estimated start time of process step 3 is May 27;

[0075] Dynamically monitor each project stage and set the initial position of each process to x k , the starting point and direction of each link process x k +1=u k (x k ), the commitment time between two adjacent process steps is d k [u k (x k )]; the maximum commitment duration is

[0076] For example: Suppose we analyze the longest committed time of the three process steps of Project 1. Through the formula, we get that the longest committed time of process step 1 is 37 days, the longest committed time of process step 2 is 33 days, and the longest committed time of process step 3 is 56 days.

[0079] For example: Assuming that the time proportions of project phase 1, project phase 2, and project phase 3 are analyzed, it is found that the time proportion of project phase 1 is 29.37%; the time proportion of project phase 2 is 26.19%; and the time proportion of project phase 3 is 44.44%.

[0080] See also Figure 3 , extract key links from the project phases, and use the formula Calculate the position of the key link; where m represents the key link, f(m) is the longest committed time from the start link of the current stage to m, n is the current stage, and R(n) is the longest committed time of the current stage. is the proportion of the current stage, Y n is the display ratio of the current stage;

[0086] The difference d of the link process is retrieved. When the difference d is greater than 0, the status information of the link process is updated to be completed in advance; when the difference d is equal to 0, the status information of the link process is updated to be running; when the difference d is less than 0, the status information of the link process is updated to timed out, and the timeout duration is calculated. When the time duration is greater than the pause threshold, the corresponding link process is automatically paused.

[0087] Get the sum H of the longest committed time from the real-time progress of the project to the first link process; get the planned usage time through the formula (Hd), and deduce the link process where the plan is located through the planned usage time;

[0088] Let [X 1 ,X 2 ,……X n ] is the sum of the longest committed durations of all links, [f(1), f(2), ... f(n)] is the longest committed duration of each link; R(1) = planned usage duration - f(1); R(i) = R(i-1) - f(i), i>1; analyze the values ​​of R(i) and R(i-1), when R(i-1)>0, R(i)≤0, then the corresponding Xi The process of planning and calculating X i location.

[0089] For example: Assume that the existing project 3 includes 4 process steps, and the longest committed time of the 4 process steps is 10 days, 20 days, 30 days, and 15 days respectively; the current process step is 3, and it has been carried out for 15 days. The sum of the longest committed time is 45 days. The project usage time is 28 days through calculation, and the difference d=17.

[0090] The planned usage time is 11 days by adding the difference to the number of days of the real-time process; R(1)=11-10=1; R(2)=1-20=-19; the planned link process is link process 2.
