技术介绍
当前,在用于企业生产的过程控制的综合自动化系统中,节能降耗、提高经济效益、生产过程优化运行、优化控制与优化管理是企业综合自动化的主要目的。流程工业的原料连续地投入,成品连续地产出,工艺运行也在不断的变化之中,产品的成本消耗只能按某一时段(通常为月),由各级生产统计人员读取进出物流的累计值、公用工程的消耗量,有时还需要进行必要的人工处理和工序间的人为摊派,人工完成进出工厂的物料平衡和工程内部各产品的物耗分配,进行能耗控制,这个能耗是该时段产品的实际能耗的平均值。 离散工业(装配工业)和过程工业的成本核算和控制的区别是,前者有详尽而确定的明细表,即BOM(Bill of Material,物料表)表,而后者只能提供消耗指标的一个大致范围。过程工业单位产出的物料和公用工程的消耗处于不断变化的过程之中,这种消耗从而引起成本的变化又是跟非价值型的参数(温度、压力、反应程度、回流比等)相关联的,具有多变量、强耦合、非线性、时变性等显著特点。因此,在会计期末(月末),按产品归集或摊派费用和消耗,进行成本核算时,已经是一种事后的行为,企业能耗流的控制永远落后于实际发生的时间,无法实现动态的控制。为了解决这一技术问题,有必要采取一种动态物耗能耗的控制方法,实时监测生产过程中的耗能情况。 经对现有技术文献的检索发现,申请号为200710036786.2,专利技术名称为“基于AR(p)预测模型的过程工业生产过程动态成本控制方法的中国专利申请文件中揭示了一种在网络、数据库等信息技术的支持 ...
