以一种立式多通道小袋包装机为研究对象，对其进行了功能分解，并建立了功能层次模型；按照包装机处理物料、信息和能量的流程，把功能分解得到的功能元构建为包装机功能元关联图；在该图的基础上，采用启发式方法得到了模块的划分规则，并采用该规则对立式多通道小袋包装机进行了模块划分。

A vertical and multichannel pouch packaging machine was studied, its functions were disassembled and its hierarchy function model was established. The function elements of packaging machine were used to build an association chart according to the process flow of the materials treated, information, and energy. Based on the association chart, heuristic method was used to get the partition rule. The rule was applied for module partition of vertical and multichannel pouch packaging machine.
