The energy benchmark has been recognised as an effective analytical methodology and management tool that help to improve the efficiency and performance of energy utilisation. With a wide distribution and large amount of energy consumption at a low efficiency, machining systems have considerable energy-saving potential. This paper proposes a task-oriented energy benchmark in machining systems, and illustrates the concept of the task-oriented energy benchmark and indicators. A method for developing the task-oriented energy benchmark considering the certainty production task and the uncertainty production task is proposed, which lays a solid foundation for studying the energy benchmark, benchmark rating system and energy certification. Furthermore, a case study of the task-oriented energy benchmark not only verifies the reliability but the effectiveness for energy-efficient production.
能源基准已被公认为一种有效的分析方法和管理工具,有助于提高能源利用的效率和性能。加工系统分布广泛、能耗量大且效率低下,具有相当大的节能潜力。本文提出了加工系统中面向任务的能源基准,并阐述了面向任务的能源基准和指标的概念。提出了一种考虑确定性生产任务和不确定性生产任务的面向任务的能源基准制定方法,为研究能源基准、基准评级体系和能源认证奠定了坚实的基础。此外,一个面向任务的能源基准案例研究不仅验证了其可靠性,还验证了其对节能生产的有效性。
