基于类和特征的产品配置建模

Modeling of product configuration based on class & feature

通过分析目前配置建模方法中存在的一些不足,结合配置模型的特点,在建模过程中引入了类和特征的思想,提出了基于类和特征的产品配置建模方法。在该方法中,将零部件视为元件类,定义了元件类的特征属性,通过对元件类的封装和类间特征关系的建立,构建了产品配置元模型。由于类和特征的引入,该模型有利于实现与软件开发的有机结合。最后以捆钞机产品为实例,建立了产品的配置模型,并应用面向对象的方法表达配置模型。

Through analyzing disadvantages of the existing configuration models and combining characteristics of configuration models, a new configuration method--configuration model based on class and feature was put forward. In this method, part was considered as the element class and its special attributes were defined. The meta configuration model with legible hierarchy was established by encapsulating attributes of element class and defining its inheritance. Because of the introduction of class and feature, this configuration model was able to better integrate software development and realistic demands. Finally, a money-binding machine was taken as the example and its configuration model and object--oriented representation were illuminated.
