最新的工业4.0 战略要求生产系统支持物联网环境下多单元间的自主交互与联动决策,实现系统整体的智能化优态运行。其中,生产与物流单元的实时协同是保证生产流程在充足的物料供给下稳步推进的重要前提。而如何实现物联网实时数据驱动下“决策-执行”层面间的纵向动态适应、又进而实现“生产-物流”环节间的横向全局协调,最终实现生产系统的多环节动态联动运作,是目前企业面临的关键挑战。研究制造物联网驱动的“生产-物流”动态联动框架,将AUTOM标准物联网信息基础架构扩展为支持系统多层、多阶段的横纵无缝信息传递的新架构,并在此基础上提出面向典型“生产-物流”运作模式的多环节修正型动态联动运作机制。结合课题组为某大型化工产品制造企业研发的“生产-仓储”联动型成品物流管理系统对所提出的框架和机制进行示例,利用动态生产节拍联动成品仓库进行适应性排库,以提高成品入库效率及仓库利用率。为大型生产系统基于物联网的在线协同运作和自主决策控制提供了可行的实现框架与手段。

The new Industry 4.0 strategy defines the automatic interaction and dynamic synchronization among multiple production sub-systems under manufacturing internet of things(MIOT) enabled environment, aiming at maintaining the whole system in an optimally operating status. The synchronization of production and logistics sub-systems could largely enhance the overall production efficiency, yet how to vertically enable the dynamic adaption between decision and execution levels and at the same time to horizontally enable the global coordination among production and logistics sub-systems remain two key challenges of finally achieving the dynamic synchronization of production and logistics. A MIOT-enabled dynamic production-logistics synchronization framework is proposed, which extends the AUTOM information infrastructure to a production-logistics-adapted new infrastructure which supports multi-level and multi-stage seamless information exchanging, and then puts forward a multi-iteration adaptive decision mechanism to enable the synchronization of production and logistics. Finally, a practical industrial case of production-warehousing synchronization is used to demonstrate the proposed solution. A feasible MIOT-based application framework and system is provided, which enable the dynamic operation coordination and adaptive decision-making of large production system.
