Project progress management method based on critical chain

Abstract

The invention relates to a project progress management method based on a critical chain. The project progress management method based on the critical chain comprises the following steps that (1) an initialization module is started and a basic framework of project management is generated; (2) a plan making module creates webs, makes a network planning chart and establishes a personnel and resource table; (3) a plan implementation module conducts an estimation on a time limit of a project according to the mean square error method, project buffer time and feeding buffer time are worked out, an MRCPSP module is established, and a final progress planning table constrained by a project logical relationship and resources is determined; (4) a plan tracking module monitors the implementation condition of the project and recognizes a project progress risk; (5) a project statistic module conducts statistics on the project workload and the resource use condition. By the adoption of the project progress management method based on the critical chain, dynamic management of the project implementation progress and the continuous improvement on the whole project management process are achieved on the premise that constraint conditions of the implementation time of jobs and the precedence relationship between the jobs are met and the resource constrain conditions are met.

Description

technical field [0001] The invention relates to a project progress management method, in particular to a critical chain-based project progress management method. Background technique [0002] Project schedule management refers to the management of the progress of each stage and the deadline for the final completion of the project during the project implementation process. It is to draw up a reasonable and economical progress plan (including sub-plans of multi-level management) within the specified time. During the process of implementing the plan, it is often necessary to check whether the actual progress is carried out according to the plan. Find out the reason in time, take necessary remedial measures or adjust and modify the original plan until the project is completed. Its purpose is to ensure that the project can achieve its overall goals under the premise of meeting its time constraints. Project schedule management methods mainly include: [0003] (1) Gantt chart, m...
