    • A method, a device, and a corresponding system for controlling a discrete production process produce or process in a number of production steps. Each step uses a machine, so that different intermediate products are produced. Buffer times are defined and taken into account during which one machine is able to continue to operate for the duration of the failure of one of the machines of a preceding production step by processing a stock of intermediate products corresponding to the associated buffer time and stored in a buffer during the production. In this case, production data are acquired continuously for each machine and, with access to these production data, statistically averaged repair times MTTRi (Mean Time to Repair) are calculated cyclically by using a MTTR calculator. Based on these times MTTRi, buffer times are calculated by using a TP calculator and are fed to a device for controlling the production process as desired values for buffer times.
    • 用于控制分立生产过程的方法,装置和相应的系统在多个生产步骤中产生或处理。 每一步都使用机器,以便生产不同的中间产品。 规定和考虑缓冲时间,在此期间,一台机器能够通过处理对应于相关联的缓冲时间的中间产品的库存并存储在前一生产步骤中的一个机器的故障期间继续运行 生产过程中的缓冲。 在这种情况下,为每台机器连续获取生产数据,并且通过使用MTTR计算器周期性地计算MTTRi(平均修复时间)的统计学平均修复时间。 基于这些时间MTTRi,通过使用TP计算器计算缓冲时间,并将其输送到用于控制生产过程的设备作为缓冲时间的期望值。
