Firstly , as the basis of our methodology , we present a framework of an approach , semantic modeling for assembly planning , through applying semantic modeling approach into the field of assembly design and planning . moreover , by using a three levels semantic ( information ) abstract , an assembly information model is given : assembly = < name , concept / function , structure , part / feature > , and the corresponding architecture of methodology is described 装配信息建模理论方法通过将语义建模方法引入装配设计与规划研究中，提出了面向装配工艺规划的语义建模方法的主要理论框架，并进而应用产品(装配)信息的三层次抽象模式，构建了产品装配信息模型： assembly = name ， concept function ， structure ， part feature 。
