Knowledge-engineering-based automatic scheme generation and evaluation system and method

The invention discloses a knowledge-engineering-based automatic scheme generation and evaluation system. The automatic scheme generation and evaluation system comprises a project management subsystem, a demand management subsystem, a product database subsystem, a collaborative design subsystem and an electronic product design technology platform, wherein the project management subsystem is in charge of providing solving ideas and tools; the demand management subsystem is used for decomposing the product design demand, converting into task indicators and multi-level task sequences, realizing dependence mapping and providing real-time monitoring of the indicators; the product database subsystem is used for managing design data and setting data standards and regulations; the collaborative design subsystem plays the role of a bridge; the electronic product design technology platform is in charge of generalizing and managing typical data, design methods and digital prototype models of all products and pushing information to the collaborative design subsystem. A method comprises the steps of knowledge extraction and classification, professional knowledge base setting, knowledge-engineering-based platform construction and automatic design scheme generation and evaluation. According to the invention, knowledge engineering is introduced into the electronic product design, so that the reuse rate of knowledge and other resources is effectively improved, automatic generation and evaluation of product schemes are realized, the product research and development time is shortened and the intelligence degree is high.
