In recent years, to attain a competitive edge, merely optimizing the production efficiency is no longer the whole story that the manufacturing enterprises concentrate on. Instead, the increasing energy costs are driving manufacturing enterprises to seek an energy-oriented approach further to improve the overall performance of the production systems. Therefore, an opportunistic maintenance policy under energy and quality constraints is developed for a degrading batch production system in this paper. First and foremost, the degradation process of the production system is modeled using the Lévy-type processes, meanwhile, the concept of the multielement-dependent degradation model was first put forward to describe the energy and quality degradation in production systems during the work period. Secondly, the degradation constraint threshold, energy constraint threshold, and quality constraint threshold are developed to determine the maintenance groups which include the machines that require two types of maintenance, preventive and corrective. Subsequently, in order not to interrupt the batch production activities, the changeover time between every two batches is regarded as an energy saving window to perform maintenance actions for the integrated maintenance groups. Thirdly, an energy-oriented integrated model that optimizes the total cost rate in consideration of energy and quality is developed, and the optimal maintenance combination scheme can be obtained by the Monte Carlo method. Finally, a numerical example is used to prove the effectiveness of the proposed policy.

能源和质量约束下基于能源的维护策略,用于依赖多元素的降解批生产系统

近年来,为了获得竞争优势,仅优化生产效率已不再是制造企业关注的全部内容。取而代之的是,不断增长的能源成本正推动制造企业寻求以能源为导向的方法,以进一步改善生产系统的整体性能。因此,本文针对退化的批量生产系统,提出了在能量和质量约束下的机会维护策略。首先,首先使用Lévy型过程对生产系统的退化过程进行建模,同时,首先提出了依赖多元素的退化模型的概念来描述工作期间生产系统中的能量和质量退化。其次,退化约束阈值 制定能源约束阈值和质量约束阈值以确定维护组,其中包括需要两种类型的维护(预防性和纠正性维护)的机器。随后,为了不中断批生产活动,每两批之间的转换时间被视为执行集成维护组维护操作的节能窗口。第三,建立了以能源和质量为基础优化总成本率的面向能源的集成模型,并通过蒙特卡洛方法获得了最优的维修组合方案。最后,通过数值算例证明了所提策略的有效性。制定质量限制阈值来确定维护组,其中包括需要两种类型的维护的机器:预防性和纠正性。随后,为了不中断批生产活动,每两批之间的转换时间被视为执行集成维护组维护操作的节能窗口。第三,建立了以能源和质量为基础优化总成本率的面向能源的集成模型,并通过蒙特卡洛方法获得了最优的维修组合方案。最后,通过数值算例证明了所提策略的有效性。制定质量限制阈值来确定维护组,其中包括需要两种类型的维护的机器:预防性和纠正性。随后,为了不中断批生产活动,每两批之间的转换时间被视为执行集成维护组维护操作的节能窗口。第三,建立了以能源和质量为基础优化总成本率的面向能源的集成模型,并通过蒙特卡洛方法获得了最优的维修组合方案。最后,通过数值算例证明了所提策略的有效性。为了不中断批量生产活动,每两批之间的转换时间被视为节能窗口,可以对集成维护组执行维护操作。第三,建立了以能源和质量为基础优化总成本率的面向能源的集成模型,并通过蒙特卡洛方法获得了最优的维修组合方案。最后,通过数值算例证明了所提策略的有效性。为了不中断批量生产活动,每两批之间的转换时间被视为节能窗口,可以对集成维护组执行维护操作。第三,建立了以能源和质量为基础优化总成本率的面向能源的集成模型,并通过蒙特卡洛方法获得了最优的维修组合方案。最后,通过数值算例证明了所提策略的有效性。通过蒙特卡洛方法可以得到最优的维修组合方案。最后,通过数值算例证明了所提策略的有效性。通过蒙特卡洛方法可以得到最优的维修组合方案。最后,通过数值算例证明了所提策略的有效性。
