    • A production control support apparatus according to one embodiment includes processing circuitry. The processing circuitry calculates a plurality of different functions depending on respective regions of the upper bound value based on: a number of machines existing in each process; a time interval of the semi-finished products arriving at the production line; a statistical dispersion of the time interval; a time necessary for one machine in each process to process one semi-finished product; and a statistical dispersion of the necessary time; and thereby obtains a relationship between the upper bound value and the blocking probability for each of the regions, and an association of the functions of the respective regions is a function where the blocking probability monotonically decreases depending on an increase of the upper bound value.
    • 根据一个实施例的生产控制支持设备包括处理电路。 所述处理电路基于以下各项,根据所述上限值的各个区域计算多个不同的功能:存在于每个处理中的机器数量; 半成品到达生产线的时间间隔; 时间间隔的统计色散; 一个机器在每个过程中处理一个半成品所需的时间; 以及必要时间的统计分散; 从而获得每个区域的上限值和阻塞概率之间的关系,并且各个区域的功能的关联是阻塞概率随着上限值的增加而单调减小的函数。
