Project construction progress calculation method and system

Abstract

The present invention provides a project construction progress calculation method and system. The method includes the following steps that: a target project is divided into a plurality of tasks; corresponding weights are configured for each of the tasks, so that the degrees of the impact of each of the tasks on the overall construction progress of the target project can be reflected; the completion progress of each of the tasks at present is calculated according to the completed workload and planned workload of each of the task at present; and the sum of the products of the completion progressof each task and the corresponding weights is calculated, so that the current construction progress of the target project is obtained. With the calculation method of the invention adopted, the problem of large error of calculation results or high subjectivity of a calculation process of a project construction progress calculation method in the prior art can be solved, and the calculation precision of project construction progress is improved.

Description

technical field [0001] The present invention relates to the technical field of electric power engineering, and more specifically, to a calculation method and system for engineering construction progress. Background technique [0002] In project management, project schedule management has always been a key issue for researchers to study, especially for power substation projects. The project is huge and the process is complex. After each task is completed, how to effectively evaluate the progress of the overall project has always been a key issue in project schedule management. key issues. [0003] At present, there are mainly three methods for judging the construction progress of electric power projects: 1. Construction period progress method, which is mainly based on the judgment of the completion degree of the time period of the schedule plan. The progress towards completion is 20%. 2. Judgment method of labor quantity method, judge the progress according to the percentag...

[0004] However, the construction schedule method is mainly applicable to balanced projects, that is, the daily progress and completion amount are the same, while electric power projects obviously belong to the project type with uneven investment, and the judgment of this method is generally inaccurate, with large deviations

The method of judging the amount of labor is too simple and rough. In the actual investment, the progress of the project is related to the relationship and sequence of each process. Only the actual amount of manpower is used to judge the progress. The deviation is large, especially in the actual project. There are a lot of situations where the amount of manpower cannot be put in on time, and this method also has great limitations. In addition, the planned manpower amount itself has a large deviation, so the calculation progress is not very accurate

[0005] The expert judgment method relies too much on human experience, and it is not ruled out that some experts can better judge the progress percentage of the project. However, in most cases, it is difficult to judge the progress of hundreds of interconnected processes in power engineering based on human experience alone. The judgment is accurate, but there is also a lack of quantitative basis and large deviations
