S88 给系统工程师提出了设计批量控制系统的指导原则,也就是 S88 标准的核心思想,那就是配方与设备控制程序相分离。这里所说的分离,指的就是配方的设计与设备控制程序的设计相互独立。将设备控制程序设计成一种相对固定的模块,这种模块被称为设备的程序元素。配方与设备控制程序仅仅在控制配方的程序元素与设备的程序元素之间实现结合,在其它方面两者不存在直接联系。配方的程序元素与设备要求这两项信息保证控制配方、不产生歧义地关联到某一特定设备的程序元素。
由此可见,要实现一个批量控制策略,首先必需进行过程分析,即分析一个产品批量生产过程的操作顺序。对批量生产过程进行分析时,一般通过带控制点的工艺流程图来了解被控对象,熟悉生产工艺,研究和分析批量生产过程固有的分层结构和模块化属性。进行过程分析的目的,是按照ISA S88标准中的物理模型来正确地划分设备单元、辨识产品的生产路径、各个元器件和设备的联锁保护以及按照程序控制模型来辨识基本的阶段。将工厂划分为设备单元,随之决定系统的最终规模,然后,把产品的生产程序在各个设备单元上分解为设备单元程序。设备单元程序是发生在一个单独的设备单元中的一组按顺序执行的操作,这些操作再细分为阶段。
