Project management progress arranging method and project management progress arranging system

The invention provides a project management progress arranging method and a project management progress arranging system which aim at re-optimizing a progress plan to enable resource allocation of a project to be optimal at any time. The project management progress arranging method includes the following steps: (1), generating a project quantity list, namely decomposing a building information model into work packages, reading material information in the work packages and creating the project quantity list according to defined project quantity calculating rules; (2), generating a progress plan, namely calculating labor time and forming the progress plan on the basis of the project quantity list and according to constraint conditions like a logical relationship between labor quotas and processes and total resources; (3), optimizing the progress plan, namely optimizing the progress plan within a reasonable time limit and based on a PSO (particle swarm optimization) algorithm to obtain an optimal progress schedule meeting requirements of optimization of resource allocation.
