摘要

本文介绍了如何在Digital Twin平台上构建可重构的互操作缓冲区系统。互操作生产缓冲器现在在生产中广泛使用。它们对生产系统的影响可以从减少停机时间中看出。从基于成本的角度来看,互操作生产缓冲区可能会从减少在制品数量中获得收益,从而提高生产性能。这个比率取决于缓冲器所含产品的平均数量。缓冲区中的平均块数受缓冲区容量的限制。生产过程中湍流的影响可以精确地观察到操作间生产缓冲区的平均含量。如果我们想要维持在制品的最优值,就有必要计算和维持生产线上每个互操作生产缓冲区的最优容量。在智能工厂的背景下,目前有可能根据当前的生产状态维持互操作生产缓冲区的当前容量。在主体系统中,真实生产设施作为自主代理通过物联网相互通信,根据计算缓冲区最优容量、故障预测和协商的公式确定缓冲区,从而主动保持中间运行生产缓冲区的最优容量,以支持智能工厂。

Concept of Reconfigurability in Interoperation Manufacturing Buffers for Smart Factory
Abstract In this article, it is described how the reconfigurable inter-operational buffers system built on the Digital Twin platform. Interoperating production buffers are now widely used in production. Their effect on the production system can be seen in decreasing downtime. From a cost-based point of view, the interoperating production buffers may generate a gain from the reduction in the volume of work-in-process, with which we increase production performance. This ratio depends on the average number of products that the buffers contain. The average number of pieces in the buffer is limited by the capacity of the buffer. The impact of turbulence in production is seen precisely on the average content of inter-operational production buffers. If we want to maintain work-in-process on optimal values, it is necessary to calculate and maintain the optimal capacity of each interoperating production buffer on the line. In the context of Smart Factory, it is currently possible that the current capacity of the interoperating production buffers is maintained according to the current state of production. In the subject system, real production facilities communicate with each other through the IoT as autonomous agents, which are decided on the basis of a formula to calculate the optimal capacity of the buffers, the prediction of faults and negotiation, thus actively maintaining the optimal capacity of intermediate operating production buffers for Smart Factory support.
