| 1. | In order to build the function model for the mold enterprise , according to the idefo method , functions of the mold enterprise were divided from top to bottom , and the function trees such as the management function tree , the technology function tree and the manufacturing function tree were established respectively . based on those trees , the top - layer idefo function graph , o - layer idefo function graph , etc . were set up , in order to build the information model , following processes had been done : 1 郑州大学硕士学位论文按照idefo方法,本文首先将模具企业自顶向下按递阶层次进行功能分解,划分为经营管理、工程技术分析与模具制作三方面,对这三个方面进行分析与细分后,可以分别得到其功能模型功能树图,对各功能树继续采用idefo方法,可以绘制出包括企业功能模型顶层idefo图、企业功能模型0层idefo图等各级功能模型图,从而完成系统功能模型的建立。 |
