Efficient Energy Use in Manufacturing Systems—Modeling, Assessment, and Management Strategy

Abstract

Currently, studies on the energy efficiency of manufacturing systems usually lack synthetic and systematic techniques. In this paper, a holistic framework is demonstrated in order to achieve more sustainable manufacturing, which covers machine-level, system-level and life-cycle-level energy efficiency techniques. Based on these, the mechanism of how energy consumption is affected by machining processes and system operation is analyzed to achieve a comprehensive decision on energy efficiency optimization. Four main topics are included in this paper: (1) Hierarchical sustainability goals and metrics for energy-efficient manufacturing; (2) Machine-level machining processes optimization for energy efficiency enhancement; (3) System-level innovations for efficient consumption management; (4) Life-cycle level energy flow modeling and energy recycling strategy. An automotive engine manufacturing system is taken as an example to build a concrete understanding of the application of the framework. Moreover, this holistic framework establishes the theoretical basis for promoting the energy efficiency of automotive engine manufacturing systems. Furthermore, the proposed techniques can provide decision-making support for achieving sustainable manufacturing in a wider scope of mechanical manufacturing.

Learning dispatching rules via novel genetic programming with feature selection in energy-aware dynamic job-shop scheduling

“…Several studies have demonstrated that energy consumption can be effectively reduced through the implementation of green scheduling, which involves the consideration of traditional scheduling objectives and environmental factors 3 , 4 . In sustainable manufacturing, the energy issue is taken into account at three levels: the product level, the machine level, and the production system level 5 . The present study centers on the production system level, with the aim of minimizing energy consumption without necessitating the re-engineering of machines or products.…”

Low-Carbon and Energy-Saving Path Optimization Scheduling of Material Distribution in Machining Shop Based on Business Compass Model

“…The development of industrial enterprises has promoted the social economy but, at the same time, brought troubling environmental problems. Environmental and energy problems have become the focus of social development [1][2][3]. For manufacturing enterprises, each link has a large amount of carbon emissions, among which transportation is a link of concentrated energy consumption, and the transportation process generates a large amount of carbon dioxide [4].…”
