Energy saving in production plants is becoming more and more relevant due to the pressure from governments to contain the environmental impact of manufacturing and from companies to reduce costs. 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 production is not critical and on when the part flow has to be resumed. A general policy is formalized by modelling explicitly the energy consumed at each machine state. The policy parameters that minimize the requested machine expected energy are provided analytically for general distributions. Numerical results are based on data acquired with dedicated experimental measurements on a real machining centre, and a comparison with the most common practices in manufacturing is also reported.

对“随机到达机床的节能控制策略”的更正

由于政府要求抑制制造对环境的影响以及公司降低成本的压力，生产工厂中的节能变得越来越重要。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打开机器。通过明确建模每个机器状态下消耗的能量，可以制定一项通用策略。对于一般分布，通过分析提供了使所请求的机器预期能量最小化的策略参数。
