Abstract

In order to meet the customer ‘s demand for product customization and to solve the problem of complicated BOM configuration and product parameter calculation in manufacturing enterprises, we design a configurable BOM model and realize a dynamic calculation engine of product parameters based on the model. The configurable BOM model abstracts key entities such as product, product attribute, material, material attribute, material brand, and so on. It realizes flexible expansion of customized product and its materials. In order to get the key parameters of the product, such as raw material cost, sale price, etc., the key parameter’s expressions of the product are dynamically configured, the values of product attribute and material attribute are used as input parameters and the real-time dynamic calculation is realized by using the algorithm based on the JavaScript engine-Mozilla Rhino, which makes the parameter calculation logic decoupled from the business logic and achieves the scalability of the product parameter calculation. The validity of the configurable BOM model and the calculating engine of product parameters are illustrated by an example of BOM structure and raw material cost calculation of a flat box in carton manufacturing industry.
