在生产各种产品的工厂，如专用集成电路或微型计算机，有必要检测任何导致瓶颈的机器，并使其恢复到高水平的性能，以实现快速有效的生产。本文介绍了一种“正义/道德”（just time process control system/最优缓冲限制和调整逻辑方法）工作流控制系统，它能动态检测出产生瓶颈的机器，并在适当的时间将工作馈送给该机器。该系统的优点如下：(1)制造周期时间可平均减少13%，最多可减少50%；(2)吞吐量可增加约10%。这个系统的一部分已经在我们工厂安装了。在1998年7月至9月的两个月内，我们发现工厂的生产周期缩短了约20%。此外，造成瓶颈的机器被迅速发现；结果，这台机器的利用率提高了3%。
At a factory which produces a wide variety of products such as ASIC's or microcomputers, it is necessary to detect any machine causing a bottleneck and return it to a high level of performance for fast and effective production. This paper introduces a workflow control system called "JUSTICE/MORAL" (just time process control system/method of optimum-buffer restriction and adjustment logic) which dynamically detects a machine causing a bottleneck and feeds work to that machine at an appropriate time. The advantages of this system are as follows: (1) manufacturing cycle time can be reduced by an average of 13% and a maximum of 50% and (2) throughput can be increased up to approximately 10%. Part of this system has been installed in our factory. We have seen factory cycle time improve by approximately 20% in the two month period from July to September 1998. Also, the machine causing the bottleneck was found quickly; as a result, the utilization of this machine increased by 3%,.
