Research on the operation model of green supply chain (Part 1)

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 located in the 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. In order to solve this problem, the idea of system and integration is introduced into the process of green manufacturing and environmental management, and the green supply chain is proposed

supplychainoperationreferencemodel, The SCOR model Ganeshan and Hardson define the supply chain as: "the 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 the supply chain varies with industries and enterprises, the 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 carry out strategic enterprise management, i.e. strategiyenterprisemanagement, SEM. The model divides the supply chain into five processes: planning, material acquisition, manufacturing, delivery and reverse logistics A process can be divided into the following five processes: planning, material acquisition, manufacturing, delivery and reverse logistics. There are three levels in total

The first layer of the SCOR model describes five basic processes, as shown in Figure 1: plan, purchase, make, ship, deliver, and reverse logistics return. It defines the scope and content of the supply chain operation reference model, and determines the basis for the competitive performance objectives of enterprises. The second layer of SCOR model is the configuration layer, which consists 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 "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 and involves 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 from material acquisition, processing, packaging, storage, transportation, use to scrap disposal." In general, the green supply chain can be seen as the idea of green manufacturing running through the whole process of the traditional supply chain. Therefore, the idea of green manufacturing can be integrated into the SCOR model of the traditional supply chain and transformed into the operation model of the 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 product life cycle from concept formation to product scrapping treatment at the beginning of design, including quality, cost, schedule, user demand, optimal utilization of resources, waste generation and recycling. In general, the whole supply chain is divided into the procurement link, the manufacturing link, the payment link and the recycling link of the green supply chain. The requirements of green manufacturing are followed in each link, and the whole supply chain is managed as a green system

3 program analysis of green supply chain operation model

3.1 procurement link of green supply chain

green procurement implements 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 demand for environmental protection products and reduce the cost as a whole. Therefore, the policy and practice of green procurement also require that the group heating among the electronic universal experimental machine industries 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 material use 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 in which enterprises and suppliers share information about inventory and demand, and enterprises adjust their plans and implement delivery in real time according to the supply situation of the supply chain. 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 the supply chain management digital display hydraulic electronic universal testing machine is the latest product management, the procurement activities are carried out in an order driven manner, and the demand for manufacturing orders is generated 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 and reduce inventory costs

3.2 manufacturing link of green supply chain

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

3.2.1 green design  7 . Green design  greendesign  includes the whole process of product life cycle from conceptual design to production, manufacturing, use and even recycling, reuse and disposal after abandonment. Green design examines the whole product life cycle from the perspective of sustainable development and emphasizes systematic analysis and evaluation from the perspective of life cycle in the product development stage to eliminate potential negative impact on the environment, And the 3R  reduce, reuse, recycle  is directly introduced 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) to achieve a win-win situation for the whole green supply chain

3.2.2 selection of green materials. As a relative concept, green material 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 materials for green products requires that environmental protection factors, engineering properties of materials, manufacturability, reliability, maintainability, etc. should be taken as the material selection objectives, 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 timely put forward updated objectives 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 ", bringing environmental protection into the decision-making elements of enterprises and paying attention 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 the waste products for recycling;  5  protect  rescue  actively participate in the environmental cleaning activities in the community, carry out green publicity for employees and the public, and establish a green corporate image
