Due date control (DDC) can be regarded as one of the competitive abilities of an enterprise. Based on advanced connected technologies implemented in Industry 4.0, DDC can collect processing information accurately and in real time to be integrated with production systems. It is an intelligent event-driven feedback control that can be designed to control process plans. In this study, a work-in-process alert system framework is developed based on a machine-to-machine communication approach. Subsequently, a manufacturer can monitor and perform DDC for each process based on the buffer control of the theory of constraints. The latter is a methodology for identifying the most important limiting factor, such as constraints, that prevents the attainment of a goal and then systematically improves that constraint until it is no longer the limiting factor. Furthermore, using hybrid strategies of Industry 3.5, a material planner can collaborate with suppliers to improve delivery performance. This approach is effective in semiconductor manufacturing.

到期日控制（DDC）可视为企业的竞争能力之一。DDC基于工业4.0中实施的先进互联技术，可以准确、实时地收集加工信息，并与生产系统集成。它是一种智能的事件驱动反馈控制，可设计用于控制过程计划。在这项研究中，基于机器对机器通信方法开发了一个在制品警报系统框架。随后，制造商可以基于约束理论的缓冲区控制对每个过程进行监控和执行 DDC。后者是一种确定最重要的限制因素（例如限制因素）的方法，这些因素会阻止实现目标，然后系统地改进该限制条件，直到它不再是限制因素。此外，使用工业 3.5 的混合策略，物料计划员可以与供应商协作以提高交付绩效。这种方法在半导体制造中很有效。
