Fig. 4 is a flow chart of a thermal power plant technology retrofit project progress management method according to the present disclosure.

The method comprises the following steps of:

(1) And estimating the working procedure time, and determining the activity construction period by applying the expected value of the triangular fuzzy variable.

Firstly, the process duration of a similar project in the past is called to obtain values of the duration a, m and b of each process, a decision maker preference index k is calculated, and the expected value of a triangular fuzzy variable is used for calculating the construction period of each activity, wherein the formula is as follows:

wherein:

ti-construction period of step i;

k—decision maker preference index;

a-the shortest time, i.e. the time required for the fastest completion of the process;

b-the longest time, i.e. the time required for the slowest completion of the process;

m-the most probable time, i.e. the time most probable to be needed for completing the procedure under normal construction conditions.

According to the influencing factors (construction difficulty, construction conditions, process risk index, process duration proportion and uncertainty coefficient) of the process construction period, the weight vector of each factor is calculated by using a hierarchical analysis method, and then the decision maker preference index k is obtained, wherein the k value is between 0 and 1.

(2) And drawing a project improvement progress plan according to the construction period of each working procedure, and finding a key path.

(3) The problem of resource conflict can occur when the working procedure is found out, and the resources are rearranged until the working procedure has no resource conflict, so that the key chain is obtained through adjustment.

(4) A buffer area is provided.

The buffer area influencing factors mainly comprise project complexity, working procedure construction difficulty and working procedure materialsThe source use condition and the decision maker preference calculate the item complexity entropy S respectively ₁ Entropy S of procedure construction difficulty ₂ Resource constraint entropy S ₃ An initial buffer of items and an import buffer of non-critical chains are calculated.

The new project buffer calculation method is as follows:

wherein:

SB-initial item buffering

number of steps on n-Key chain

S ₁ -project overall complex entropy

S _2i Construction difficulty entropy

S _3i Resource constraint entropy

k _i Decision maker preference factor

σ _i Safety time of step i

The method for calculating the import buffer is as follows:

HB _m inlet buffering of mth non-critical chain

number of steps on n-related link

S _1j Single complex entropy of process j on the nth non-critical chain

S _2j Construction difficulty entropy

S _3j Resource constraint entropy

k _j Decision maker preference factor

σ _j Safe time of Process j

After the project buffer and the import buffer are established, when the non-key chain is added into the import buffer and is larger than the key chain, the key chain is changed; or that activities on the critical chain cannot be performed continuously. A modification to the buffering on the non-critical chain is required, i.e. modifying the project buffering to be the sum of the project buffering and the redundant buffering on all non-critical chains.

(5) Buffer monitoring.

In order to ensure that the project is completed according to the schedule, a project schedule is prepared, and various unexpected incidents can occur in the actual construction process along with the continuous progress of the project, so that the deviation of the actual schedule of the project and the schedule occurs. At this time, effective management measures are required to monitor the progress of the project. The key chain technology described in the invention introduces the concept of a buffer zone, namely, the buffer zone concentrated at the tail end of a link is used for replacing redundant safety time dispersed in each procedure, so that the construction period can be saved, and effective monitoring of projects is facilitated. The invention simplifies the monitoring of project progress to the monitoring of the buffer area.

In the construction process of the project, different working procedures are affected by different uncertainty factors, the consumption proportion of buffering is also different, and the buffer amount consumed by each working procedure can affect the subsequent working procedures. For the already completed process, the risks and uncertainties faced by it are completely eliminated and their effect on the total working period can no longer be taken into account. The remaining buffers are re-allocated without consideration of the finished process. Based on such consideration, during the implementation of the project, as the uncertainty of the project is gradually reduced, the buffer is dynamically allocated in combination with the actual condition of the project.

The core of the dynamic monitoring is to determine a trigger point, and the invention sets the trigger point as 1, and monitors each procedure once every time one procedure is completed. 2. The execution condition of the project is updated, monitoring is immediately carried out when needed, and when the threshold alpha > 1, namely the buffer size required by the plan of the rest part of a certain process is larger than the actual rest buffer size of the process, corresponding action is needed to be immediately taken.

Aiming at the limitations of the existing progress management method, the invention provides a new and improved progress management method for thermal power plant technical transformation project, 5 constraint factors influencing project estimation of technical transformation project are comprehensively considered on the original basis through an improved key chain technology, a fuzzy theory is introduced to adjust the project, then a resource constraint is identified on the basis of a network planning technology by adopting the key chain technology, parallel procedures with the resource constraint are adjusted to obtain a key chain, and buffering is inserted in a concentrated mode at the tail end of the link, so that the project period is shortened, and the project cost is saved.
