Multistage network planned schedule analysis method

Abstract

The invention discloses a multistage network planned schedule analysis method based on a multistage network planning model, which firstly establishes the multistage network planning model and comprises the following steps: (1) extracting a multistage network plan; (2) arranging a front and rear arrangement relation of the plan; (3) arranging a planning proposal mode; (4) carrying out loop checking to check whether the front and rear arrangement relation of the plan forms a loop or not; (5) executing schedule calculation; and (6) recording the schedule calculation result. According to the invention, on the basis of plan starting time, plan completion time and plan construction period of each plan, the expected starting time, the expected completion time and the plan construction period of the plan are calculated according to the front and rear arrangement relation of the plan and father and son constraint; and on the basis of the expected starting time, the expected completion time and the plan construction period, users can search a critical path, and systematically analyze the longest construction period of the item, the probability of finishing the item on the schedule and other important indices, so as to achieve the purposes of saving cost and shortening the construction period by utilizing a network optimization method.

Description

technical field [0001] The present invention relates to a progress analysis method of a multi-level network plan. Background technique [0002] As we all know, aerospace model engineering is a group management engineering project with very complex cooperation relationship and difficult risk control. With the vigorous development of my country's aerospace industry, the scale of the project has become more and more complex, and there are more and more factors restricting the project, and the pressure to seek benefits through refined management is increasing. Under such circumstances, how to smoothly advance the project progress, make the project well-controlled within the scope of the plan, and ensure that the project achieves its goals "faster and better" is an urgent problem to be solved. At present, in the project management software market, Primavera's P3, P6, Microsoft's Project, etc. are used more. However, in terms of schedule calculation, P3 and P6 do not yet support...
