### Sustainable Development  
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs [4], and global sustainable development is still gradually increasing and spreading all over the world [5]. In addition, sustainability includes three dimensions, namely cultural sustainability, social sustainability, and economic sustainability [4; 6]. In order to achieve sustainable development, environmental policies on pollution prevention have shifted from the end-of-pipe approach to front-end preventive control [7]. Manufacturing is the main component of the world's resource consumption and waste generation. From 1971 to 2004, the energy consumption of the world's manufacturing industry increased by 61% and accounted for nearly one-third of global energy use [8]. In contrast, the manufacturing industry has the potential to become a driving force for creating a sustainable society that can design and implement integrated sustainable practices and product and service development to help achieve better environmental performance [9]. Therefore, the concept of sustainable manufacturing came into being. By incorporating the spirit of sustainable development into products and services, the manufacturing and service industries can protect the environment and create their own profits while meeting customer needs and give back to society to achieve a sustainable enterprise with a long-lasting foundation [10; 11]. Thus, sustainable manufacturing promotes minimizing or eliminating production and processing waste through eco-efficient practices, and encourages the adoption of new environmental technologies [11]. In order to realize sustainable manufacturing, there are more and more studies on sustainable green manufacturing. The topics include the rising cost of energy and resources, the risks of suppliers, consumer demand, policies and laws, reducing the influence on environmental impact, and so on [12]. For this reason, the important content of sustainable competitive advantage includes: (1) economic performance: cost reduction, market share growth, profit margin increase, avoiding unnecessary environmental penalties, etc. ; (2) environmental performance (ecological performance): compliance with environmental regulations, controlling relevant pollution, recycling measures, etc. ; and (3) social performance: social responsibility appraisal, corporate environmental image, customer satisfaction, customer and stakeholder attention, etc. [13]. Among them, environmental performance is positively helpful in improving economic performance. Improving environmental performance means having a better opportunity to enter certain specific markets, having the opportunity to differentiate products, and being able to promote pollution prevention technologies. In addition, improving the environment performance can reduce material costs, energy and service costs, and labor costs [14]. Industrial sustainability refers to the end state of a transformation process where industry is part of, and actively contributing to, a socially, environmentally, and economically sustainable planet. There is a three-stage change including efficiency, technology, and system changes in industrial sustainability [15]. About society's consumption of natural resources and the impact of industrial activities, operation changes and equipment design for reduced energy consumption are discussed for process-related research, and new developments in process planning and production scheduling are highlighted that consider environmental performance [16; 17]. Therefore, how to reduce the impact of the manufacturing process on the environment can be roughly divided into three categories: (1) Process improvement and optimization: the process is high-efficiency and low-cost and environmental issues are addressed. (2) New process development: new \"green\" processes are developed to replace traditional processes.
