Product configuration method and system supporting multilevel platform

Abstract

The invention discloses a product configuration method and system supporting a multilevel platform. According to the method, an enterprise-level product platform main structure is established according to division of a product platform in an enterprise; all sub-platform main structures and a bottommost product family main structure are sequentially established on the basis of the enterprise-level product platform main structure; according to a product configuration demand, a variable condition is defined for a module selected by the product family main structure; according to the product configuration demand, whether a sub-module meeting the variable condition exists in the product family mains structure is judged, and whether the sub-module is associated with the variable condition is judged; the product platform main structure is traversed according to a product configuration demand table, assignment is performed on node variables, and a constraint relation and the module not meeting the demand are removed till all the variables are subjected to assignment; and finally a product variable general bill of materials (BOM) containing the variable condition is screened out, instance components are used to replace corresponding nodes in the product variable BOM, an engineering general BOM is formed, and a design result is output.

Description

technical field [0001] The invention relates to a product configuration method and system supporting multi-level platforms. Background technique [0002] Product configuration is one of the core technologies of Mass Customization (MC) production mode. In order to better meet the individual needs of customers and at the same time reduce costs through economies of scale, product configuration technology based on product platforms is becoming the focus of attention of various manufacturing companies. The core idea of ​​"platform strategy" is to establish a collection of general product modules, that is, product platforms, based on similarities in product functions, structures, or engineering solutions, and to derive personalized products based on this. [0003] Usually, multiple product families can be derived from the same product platform, and each product family has many similarities and differences, such as structural composition, technical constraints, and material charac...

Problems solved by technology

[0004] However, scholars at home and abroad seldom study product configuration from the product platform, mostly based on the product family, and study how to configure personalized products based on the product family. Configuration templates, through the interchange, adaptation and coordination of units to configure products that meet customer needs, Dong Yuanfa constructed a product family constraint network model that includes demand elements and configuration elements, and obtained configuration results that meet customer needs by solving the constraints set, Ostrosi proposes a distributed fuzzy configuration model to solve the collaborative design problem in product configuration based on product family

The research and application of product platforms in China has just started. Although many companies have developed product platforms, they often only use the idea of ​​product platforms to divide platform modules and personality modules, and the process of product configuration still adopts traditional variable configuration. method, does not really realize the configuration based on the product platform, and the configuration efficiency is not high
