Method and device for predicting stage of decoration project and material data based on historical material data

The invention provides a method for predicting stages of a decoration project and decoration materials based on historical material data. The method comprises the following steps: creating the decoration project; setting a project stage; obtaining decoration material data purchased by the decoration project; the decoration material data comprises commodity categories and purchase quantity; evaluating the project stage of the decoration project based on a project stage prediction algorithm; the project stage prediction algorithm is a data model obtained by analyzing historical transaction data of a confirmed project stage; the project stage prediction algorithm is also used for obtaining a current project stage, a future project stage and decoration materials corresponding to the project stages; and setting a current project stage and a future project stage of the decoration project according to an evaluation result of the previous step, and obtaining corresponding decoration materials.
