One of the measures for saving energy is the implementation of control strategies that reduce energy consumption during the machine idle periods. This paper proposes a framework that integrates different control policies for switching the machine off when the production is not critical, and on when the part flow has to be resumed. A general policy is formalized by modeling explicitly the power consumed in each system state. With this policy, the service can be resumed according to time threshold and when parts have accumulated in the buffer. The behavior of the control strategy under different scenarios is numerically evaluated. Numerical results are based on data acquired with dedicated experimental measurements on a real machining center. A comparison with the common practice in manufacturing and with control policies that do not consider buffer information is also reported.

对“具有随机到达和缓冲区信息的机床节能切换的分析”的更正

节能的措施之一是实施控制策略，以减少机器空闲期间的能耗。本文提出了一个框架，该框架集成了不同的控制策略，用于在生产不重要时关闭机器，在必须恢复零件流时关闭机器。通过显式地建模每个系统状态下的功耗来制定通用策略的形式。使用此策略，可以根据时间阈值以及缓冲区中已积累零件的时间恢复服务。对不同情况下控制策略的行为进行了数值评估。数值结果基于在真实加工中心上通过专用实验测量获得的数据。
