Abstract
Climate change mitigation, the goal of reducing CO2 emissions, more stringent regulations and the increment in energy costs have pushed researchers to study energy efficiency and renewable energy sources. Manufacturing systems are large energy consumers and are thus responsible for huge greenhouse gas emissions; for these reasons, many studies have focused on this topic recently. This review aims to summarize the most important papers on energy efficiency and renewable energy sources in manufacturing systems published in the last fifteen years. The works are grouped together, considering the system typology, i.e., manufacturing system subclasses (single machine, flow shop, job shop, etc.) or the assembly line, the developed energy-saving policies and the implementation of the renewable energy sources in the studied contexts. A description of the main approaches used in the analyzed papers was discussed. The conclusion reports the main findings of the review and suggests future directions for the researchers in the integration of renewable energy in the manufacturing systems consumption models.
Highlights
Introduction and Review MethodologyIn the last five years, as reported in [1], energy-related CO2 emissions have risen 1.3%per year
The cutting energy and the cutting time were considered as objectives in the machine tool level, whereas in the shop floor level the makespan and total energy consumption were defined as the targets; the optimization was achieved using grey relational analysis and a genetic algorithm respectively at the machine and at the line grade
Lei et al [105] developed a two-phase meta-heuristic based on the imperialist competitive algorithm and variable neighborhood search in order to achieve a solution for the flexible job shop scheduling problem; the proposed algorithm allows obtaining the minimization of the total tardiness and of the makespan, considering total energy consumption as a constraint
Summary
In the last five years, as reported in [1], energy-related CO2 emissions have risen 1.3%. Energy efficiency and renewable energy sources may provide more than 80% of the emission savings required [2]. This work aims to provide a comprehensive review of the main papers regarding the sustainability and energy efficiency in manufacturing. The number of articles regarding energy efficiency and sustainability, analyzed in this review from 2007 until June 2021, is reported in the following figure (Figure 1). The first and the second group collected the papers regarding energy efficiency respectively in the manufacturing system and assembly line context.
