基于广义产品结构的产品配置

Product configuration based on generic product structure

针对传统的基于结构的产品配置方法中,零部件之间约束关系表达能力较弱的问题,将基于规则的方法和基于结构的方法相结合,给出了一种基于广义产品结构的产品配置模型和配置求解方法。该模型采用基于结构的方法描述配置知识的结构信息,采用基于规则的方法描述配置约束信息,增强了对配置约束的描述能力。配置求解方法中,提出了配置推理图的概念,并基于先根遍历访问模型中的节点,采用数据驱动的深度优先图搜索策略求解每个节点的配置约束,提高了配置求解能力。最后通过一个应用示例,给出了基于该产品配置模型的配置求解工作过程。

In traditional structure-based Product Configuration（PC） method,the expression capability of the constraint relationship among parts was weak.To tackle this deficiency,a PC model and a configuration solving method based on generic product structure were presented,in which the structure-base method was combined with the rule-based method.In this model,the structure information was expressed by the structure-based method and the configuration constraint information was expressed by the rule-based method so as to enhance the expression capability of the configuration constraint.In the configuration solving method,a configuration reasoning graph was proposed.The nodes in the PC model were accessed with preorder tree traversal method and the configuration constraint of each node was solved by depth-first graph search method,the configuration solving capability was enhanced.Finally,an application demonstration was provided to illustrate the solving process based on the PC model.
