基于产品特征向量的产品配置知识表达

Knowledge Expression of Product Configuration Based on Product Characteristic Vector

针对产品配置对不同产品的适应能力差、配置知识表达复杂的现状,提出基于产品特征向量的知识表达方法。在产品特征可量化的条件下,建立基于产品特征向量的产品配置模型,给出知识表达的理论基础和实现步骤。产品特征向量的引入,实现了对产品特征的自然语言描述向数学语言描述的转化;捆绑在组件上的约束和产品特征向量相关,使约束表达直观、集中,降低了知识表达的难度,并给出成功应用案例。

Aiming at the situation that product configuration can not adapt to different products and knowledge expression is complicated, product configuration based on product characteristic vector is presented. Under the condition of quantifiable product characteristics, the model of product configuration based on product characteristic vector is constructed, and the basic theory and process of knowledge expressions are given. Introducing of product characteristic vector realizes the transformation from the description of natural language of product characteristics into that of math language. Constraints attached to components are related to product characteristic vector, which makes constraint representations simple and concentrated, reducing the difficulty of knowledge expression. And a successful case is illustrated.
