Research on the operation model of green supply chain (Part I)

human society has developed rapidly in the 20th century. As a pillar industry of the national economy, manufacturing industry has not only created rich material wealth for the society, but also consumed a lot of resources and caused environmental pollution. In view of this, some scholars at home and abroad are committed to the research and application of green manufacturing, in order to make the manufacturing industry use resources most effectively and minimize the harm to the environment. In the traditional supply chain, although some enterprises in key links formulate and implement strict internal standards for environmental management, their upstream suppliers and downstream distributors do not necessarily follow the same standards, which makes the environmental management of the supply chain lack of systematicness and integrity, and can not achieve the real purpose of environmental protection at all. In order to solve this problem, the idea of system and integration is introduced into the process of green manufacturing and environmental management, and green supply chain is proposed

1 supply 1. Force measurement and discrimination rate: 0.001-0.1n (determined by range)) reference model of stress chain and supply chain operation

supplychainoperation reference model, Ganeshan and Hardson of SCOR model define supply chain as: "supply chain is a network of facilities and distribution channels that acquire raw materials, convert them into finished products and semi-finished products, and then send products to customers. Although the complexity of supply chain varies with industries and enterprises, supply chain is common in both service and manufacturing enterprises."

supply chain operation reference model (SCOR model is the most influential and widely used reference model at present. It can evaluate and improve the internal and external business processes of the enterprise, making it possible to strategically manage the enterprise  strategyenterprisemanagement  SEM. This model divides the supply chain into five processes: planning, material acquisition, manufacturing, delivery and reverse logistics, each of which A process can be divided into the following five processes: planning, material acquisition, manufacturing, delivery and reverse logistics, which have three levels

The first layer of the SCOR model describes five basic processes, as shown in Figure 1: plan, purchase, produce, use Ke in the form of liquid under arthroscopy, ship, deliver, and reverse logistics return. It defines the scope and content of the supply chain operation reference model, and determines the basis of the enterprise's competitive performance goals. The second layer of SCOR model is the configuration layer, which is composed of 26 core process types. The third layer of SCOR model is the process decomposition layer, which gives the details of process elements in each process classification in the second layer, and provides enterprises with the information needed to successfully plan and set their goals to improve the supply chain

2 green supply chain and green supply chain operation model

green supply chain is "A modern management mode that comprehensively considers environmental impact and resource efficiency in the whole supply chain. It is based on green manufacturing theory and supply chain management technology, involving suppliers, manufacturers, sellers and users. Its purpose is to minimize the negative impact on the environment and maximize resource efficiency in the whole process of product acquisition, processing, packaging, warehousing, transportation, use and scrap disposal." In general, green supply chain can be seen as the idea of green manufacturing running through the whole process of traditional supply chain. Therefore, the idea of green manufacturing can be integrated into the SCOR model of traditional supply chain and transformed into the operation model of green supply chain

The operation model of green supply chain embeds the idea of green manufacturing on the basis of the original SCOR model. It requires supply chain designers to fully consider all factors in the whole life cycle of products, from concept formation to product scrap disposal, from the beginning of design, including quality, cost, schedule, user needs, optimal utilization of resources, waste generation and recycling. On the whole, the whole supply chain is divided into the procurement link of green supply chain, the manufacturing link of green supply chain, the payment link of green supply chain and the recycling link of green supply chain. In each link, the requirements of green manufacturing are followed, and then the whole supply chain is managed as a green system

3 analysis of the operation model program of green supply chain

3.1 the procurement link of green supply chain

green procurement is to implement the awareness of preventing environmental pollution and saving energy in the whole supply chain through source control. In addition, green procurement can meet the public's demand for environmental protection products and reduce costs as a whole. Therefore, the policy and practice of green procurement also requires that the electronic universal experimental machine industry can bring economic benefits and competitive advantages to enterprises. Enterprises in the green supply chain should design the green procurement link from the following aspects:

3.1.1 selection and management of green suppliers. At this stage, it is necessary to consider whether the materials provided by the supplier are polluting, whether the manufacturing process is clean, whether the transportation process can save energy and other factors. Through communication with suppliers, enterprises put forward requirements for suppliers' products in order to reduce the use of materials and waste generation. Care about the use efficiency and environmental benefits of products to the greatest extent, and minimize the damage to the environment caused by products, so as to achieve the "win-win" of the demander, customers and the whole environment

3.1.2 implement collaborative procurement. Collaborative purchasing refers to the process that enterprises and suppliers adjust their plans and implement delivery in real time according to the supply situation of the supply chain on the basis of sharing inventory, demand and other information. Suppliers can adjust their plans in real time according to the real-time inventory, plan and other information of the enterprise, which can reduce inventory without sacrificing service level

3.1.3jit order driven purchase. Under the circumstance that supply chain management digital display hydraulic electronic universal testing machine is the latest product development, procurement activities are carried out in an order driven manner, and the demand for manufacturing orders is driven by the demand orders of users. This JIT (just in time production) order driven mode enables the supply chain system to respond to users' needs on time, while reducing inventory costs

3.2 manufacturing link of green supply chain

the manufacturing link of green supply chain includes not only the manufacturing process, but also the concept of large-scale manufacturing starting from product design, including material selection, product processing, logistics design, packaging design, product disassembly and other processes

3.2.1 green design  7 . Green design  greendesign  includes the whole life cycle process of products from conceptual design to production, manufacturing, use and even recycling, reuse and disposal after abandonment. Green design examines the whole life cycle of products from the perspective of sustainable development, emphasizing systematic analysis and evaluation from the perspective of life cycle in the product development stage, so as to eliminate the potential negative impact on the environment, And introduce 3R  reduce, reuse, recycle directly into the product development stage; Green design advocates waste free design. Green design based on green supply chain should be based on the implementation of green design by enterprises themselves, Communicate with suppliers, distributors and other partner enterprises  from the stage of product concept formation and the beginning of design, consider the greening of product life cycle from an overall perspective (including the supply and transportation of raw materials by suppliers; the selection of raw materials and product production by manufacturers; the sales of distributors and the comprehensive consideration of waste recycling and reuse)  so as to achieve a win-win situation of the whole green supply chain

3.2.2 selection of green materials. Green material is a relative concept, which is still in the process of continuous development and improvement. Green materials mainly include the progressiveness of the material itself, high-quality materials with low production energy consumption, safety of the production process, low noise, no pollution, rationality of material use, economical and recyclable materials, and compliance with the requirements of modern engineering. The selection of green product materials requires that environmental protection factors and the engineering properties of materials, such as manufacturability, reliability, maintainability, etc. should be taken as the common objectives of material selection, so that the products not only have excellent predetermined functions, but also are conducive to environmental protection and ecological environment

3.2.3 cleaner production. Cleaner production itself is a process of continuous improvement. It requires enterprises to put forward updated goals in a timely manner with the development of economy and the progress of science and technology. It requires enterprises to always consider environmental protection and reflect green in enterprise management. This idea can be summarized as the "5R" principle, that is, "1" research ", which brings environmental protection into the decision-making elements of enterprises and attaches importance to the study of environmental countermeasures of enterprises;  2  reduce, adopt new technologies and processes to reduce or eliminate the discharge of hazardous wastes;  3  redevelop  reuse  change traditional products into environmental protection products, and actively adopt "green signs";  4  recycling  recycling and recycling of waste products;  5  protect  rescue  actively participate in environmental cleaning activities in the community, carry out green publicity for employees and the public, and establish a green corporate image
