The present invention provides a product
management system, method, device and computer-readable storage medium, wherein the product
management system includes: a pre-sale product
cost calculation module, which is used to perform whole
machine detection on the imported equipment
list to determine whether the product is a configured product, and if so, continue to perform whole
machine detection of the first-level component status on all configured products in the equipment
list to calculate the pre-sale product cost; if not, continue to configure the unconfigured product; a component
cost calculation module, which is used to select materials for which component costs are to be calculated in the material
library; according to the structural relationship of the physical
library, load the bottom-level parts of the materials for which component costs are to be calculated, and calculate the cost unit price of the material according to the bottom-up hierarchical structure of the material in the physical
library. The present invention realizes the accuracy calculation of product costs and realizes the
cost calculation of multiple business scenarios.
