Visual decomposition method and system for engineering management

The invention discloses a visual decomposition method and system for engineering management, and the method comprises the steps: carrying out the entity structure decomposition of a to-be-managed engineering project based on a pre-created EBS engineering decomposition template, so as to generate an EBS directory tree; performing process decomposition on the to-be-managed engineering project based on a pre-created WBS process template to generate a WBS directory tree; binding each end node of the EBS directory tree with a corresponding process step of the WBS directory tree to generate a combined structure tree; establishing a grid space by using a BIM model of a to-be-managed engineering project, and binding each grid of the grid space with a corresponding end node of the EBS directory tree in a space mapping mode to realize visual dynamic engineering progress display; according to the method, through combined application of three decomposition types of EBS, WBS and grid space, different types of business man
