ABSTRACT

Energy management effectively reduces energy consumption, improves material utilisation, minimises emissions and maximises product output during manufacturing. Thus, enterprises are implementing an energy management strategy and improving sustainable competitive advantage. With the rapid development of the Internet of Things, Cyber-Physical Systems and Big Data, sustainable smart manufacturing provides a new strategy for energy management by applying advanced information technologies. In practice, energy management is an enormous opportunity given the lack of such implementation. This paper presents a case-practice-theory-based (CPTB) method of implementing energy management in the manufacturing factory for energy saving and emission reduction. The closed-loop structure of the proposed CPTB method is designed and implemented. Then, an application of six hot-blast stoves in moulding workshops of a partner company is presented to demonstrate the proposed method. Results showed that after employing the method, the unit energy consumption of production reduced by approximately 3%, and saved energy costs reached 4%. Finally, a discussion analyses the managerial implications for ceramic and other energy-intensive manufacturing industries.

摘要

能源管理有效地降低了能源消耗，提高了材料利用率，最大限度地减少了排放，并在制造过程中最大限度地提高了产品产量。因此，企业正在实施能源管理战略并提高可持续竞争优势。随着物联网、信息物理系统和大数据的快速发展，可持续智能制造通过应用先进的信息技术为能源管理提供了新的策略。在实践中，由于缺乏这样的实施，能源管理是一个巨大的机会。本文提出了一种基于案例实践理论（CPTB）的方法，在制造工厂实施能源管理以实现节能减排。设计并实现了所提出的 CPTB 方法的闭环结构。然后，展示了六个热风炉在合作公司的成型车间的应用，以演示所提出的方法。结果表明，采用该方法后，单位生产能耗降低约3%，节约能源成本达4%。最后，讨论分析了陶瓷和其他能源密集型制造业的管理意义。
