摘要
针对传统MES存在的业务逻辑层与数据层关系模糊、模块紧耦合等问题,提出了基于节点的MES构建方法,并引出了节点的定义及通过工作流实现节点的方法。在节点的基础上分别分析并提出了单个节点及节点集的定义、作用及实现方式,并在工作流驱动的基础上进一步提出基于节点构建方法的具体实现,从而在局部和整体两方面实现了系统功能,并消除了数据层与业务逻辑层的盲区,保证了模块之间的松耦合。
The method of MES system constructing is aimed to solve the problem exited in the traditional MES system,which is a blur relation among business logic layer and data layer and tight coupling of modules.And the definition of node and the method of work flow carrying out node are educed.Based on node,the definition,function and realizing way of single node and node gather are analyzed and put forward respectively.And further the concrete realization of the constructing method which is based on node on the foundation of work flow driving is put forward.Thus the system function is carried out in both aspects and the whole side.And the blind area between data layer and business logic layer are cleared up,the loose coupling of modules is guaranteed.
