In the light of extensive process shortages in most discrete industry , it istablishes a MES integrated model based on existing PDM .This model expounds the process generating flow of materials which is belonged to MES.It shows the detail about the process change and management of process version in MES .%针对多数离散行业工艺粗放的弊病,在现有PDM基础上构建了MES集成模型,并阐述了该模型中物料在MES内的工艺生成流程,最后对MES中的工艺变更、工艺版本管理进行了详细的分析。
