Problem-specific knowledge MOEA/D for energy-efficient scheduling of distributed permutation flow shop in heterogeneous factories

With the development of the global economy and the enhancement of environmental awareness, energy-efficient permutation flow shop scheduling gets more attention. Nevertheless, research on distributed scheduling with heterogeneous factories is scarce. In this paper, a knowledge-driven MOEA/D (KMOEA/D) is proposed to address the energy-efficient scheduling of distributed permutation flow shop problem in heterogeneous factories (DPFSP-HF) with the criteria of minimizing the makespan (Cmax) and total energy consumption (TEC). First, an efficient energy-saving strategy is proposed to reduce the TEC criteria. Second, a constructive heuristic is designed to generate a high-quality solution set. Third, an ingenious genetic operator is utilized to maintain population diversity. Fourth, the knowledge-driven local search operator combined the problem-specific knowledge is constructed according to the properties of DPFSP-HF. Additionally, the Taguchi approach is used to calibrate the parameter configuration of KMOEA/D. We evaluate the effectiveness of each improvement of KMOEA/D and compare it to other well-known multi-objective optimization algorithms on different instances. The results indicate the effectiveness of each improvement of KMOEA/D, and verify that KMOEA/D is an efficient approach to address DPFSP-HF.

Analysis of the Development Path of New Energy Vehicles Based on Technical Barriers to Trade -- Taking BYD as an Example

With the development of globalization, trade between countries is becoming more and more frequent. However, with the progress of society, the improvement of people's living standards in developed countries, and the enhancement of environmental awareness in various countries, people have more and more requirements for products. Therefore, the exploration and application of new energy are key topics today. The researchers found that the emerging new energy vehicle industry is in a stage of rapid development. However, the technical barriers to trade faced by new energy vehicles and their exports still lack a unified explanation. Therefore, this paper conducts a SWOT analysis of BYD by collecting its development status, business status, and competitors. In the context of globalization, BYD explores its development path in the face of technical barriers to trade. It is found that at this stage, BYD has alleviated the impact of technical barriers to trade by developing new energy technologies to a certain extent, but BYD still faces financial problems caused by the reduction of national financial support, and the after-sales service of new energy vehicles such as charging and insurance is not perfect. And put forward reasonable countermeasures and suggestions for the above problems.

The impacts of non-farming income on rural household energy choices: Empirical evidence from China.

This study uses data from the China Family Panel Studies to analyze the possible impact of non-farming income on household energy choices. We use ordinary least squares and instrumental variable estimation methods to investigate the causal effect of non-farming income on household energy choices. We find that an increase in non-farming income assisted farmers in reducing their use of solid fuels in favor of clean energy. Our heterogeneity analysis, based on the average rural household income and geographical location of the village, shows that the energy upgrade effect of non-farming income is more obvious in high-income areas and suburbs closer to the county seat center. Further, we find that non-farming income has an impact on rural household energy choice mainly through the optimization of household energy-saving appliances and the enhancement of environmental awareness.

Carbon Emission Reduction by Echelon Utilization of Retired Vehicle Power Batteries in Energy Storage Power Stations

With the enhancement of environmental awareness, China has put forward new carbon peak and carbon neutrality targets. Electric vehicles can effectively reduce carbon emissions in the use stage, and some retired power batteries can also be used in echelon, so as to replace the production and use of new batteries. How to calculate the reduction of carbon emission by the echelon utilization of retired power batteries in energy storage power stations is a problem worthy of attention. This research proposes a specific analysis process, to analyze how to select the appropriate battery type and capacity margin. Taking the BYD power battery as an example, in line with the different battery system structures of new batteries and retired batteries used in energy storage power stations, emissions at various stages in different life cycles were calculated; following this in carbon emission, reduction, by the echelon utilization of the retired power battery, was obtained. Finally, the overall carbon emissions that might be reduced by echelon utilization in the future were calculated according to the BYD’s battery loading volume and China’s total power battery loading volume in 2021. This research provides a quantitative analysis idea for the carbon emission reduction of power battery echelon utilization. Using this method could improve the process of echelon utilization, optimize the supply chain of power batteries, drive the development of the new-energy vehicle industry, and explore new business models, so as to achieve the environmental protection goal of carbon neutrality.

A novel approach integrating FANP and MOMILP for the collection centre location problem in closed-loop supply chain

ABSTRACT Supply chain network design plays a crucial role in supply chain management. With government support as well as restriction and legislation, the enhancement of environmental awareness, and the drive of economic interest, reverse logistics have been incorporated into the supply chain, forming a closed-loop supply chain. The collection centre, which helps recycle and classify returned products, is a vital hub in closed-loop networks. Regarding the location problem, this study proposes a novel approach that integrates a fuzzy analysis network process and multi-objective mixed-integer linear programming to analyse qualitative and quantitative factors: social, political, and environmental factors, including costs, emissions, and responsiveness. Hence, an ε-constraint method is applied to examine the proposed framework. Finally, uncertain scenarios and different scale problems are discussed. Orthogonal experiments provide a sufficient basis for decision-making.

Trans-frontier Environmental Damage in International Jurisprudence

The enhancement of environmental awareness in both domestic and international level has been accompanied by the growing number of internal authorities and international bodies within which environmentally related disputes can be addressed. Over the years, environmental issues have been discussed by different international judicial courts and arbitration tribunals. Their contribution to enhance the legitimacy of international concerns to the protection of environment is a significant one. They have acted to clarify the international environmental rules within the international legal order and have augmented the ability of domestic legal systems to deal with associated problems more effectively. The international judicial bodies as well as arbitration tribunals have been faced with a rather vague set of rules and principles that made it an enormous task to apply the law to the particular facts of a case in question. Issues relating to the existence, contents and meaning of the certain related concepts took considerable spaces in the contributions of international courts and tribunals in<em> </em>the course of developing international environmental law, particularly the concepts of environmental damage and the liable party to make reparation.<em> </em>International judicial bodies mostly relied on procedural obligations of states and arbitration tribunals on damage itself and the necessity to compensate them. While the damage is mostly confined to significant damage of value-use aspects of the environment, and liable party is focused on the damage causing activities of the operator, the reparation modes are unsteady between only financial compensation and, if possible,<em> </em>near to<em> </em>restitution.

SOCIO-ECONOMIC ASPECTS OF THE AUSTRIAN 200 kWp-PHOTOVOLTAIC-ROOFTOP PROGRAMME

Between 1992 and 1994 a 200 kWp-rooftop programme to promote small grid-connected Photovoltaic (PV) systems was conducted in Austria. Within this programme about 100 PV systems with an average capacity of 2.28 kWp were installed. This paper investigates the socio-economic aspects of this programme and the prospects for a further dissemination of this technology. The major conclusions of this investigation are as follows: (1) The motives to invest in a PV system are: (i) environmental protection; (ii) an alternative to nuclear power; (iii) technical interest. Yet, it is also important that the public supports this purchase by means providing subsidies. (2) The purchase of a PV system leads to different changes in consumer behaviour. Consumers with low initial consumption increased their electricity demand slightly, while the majority of consumers with high initial electricity demand saved electricity. (3) The financial incentives in the programme were not optimally designed. With the same amount of total subsidies it would have been possible to promote more PV systems. (4) The key factors for a further dissemination of PV systems are: (i) financial incentives; (ii) a reduction of the investment costs; (iii) increase in reliability; (iv) distribution of information; (v) enhancement of environmental awareness.
