Study On Interrelated Supply Chain Management And It's Coordination Mechanism Oriented To Resources And Environment

Facing to the serious situation of resource & environment and the fierce market competition, it has become the most important research subject that is how to utilize the limited resource efficiently, minish the damage of environment, maintain moderate economic growth, and finally achieve sustainable development of the manufacturing industry for the 21st century. Industrial waste coming from the manufacturing industry is the key factor that results in environmental pollution. From the other side, it is also another kind of resources which could be reused to create new value. The reutilization of industrial waste is one of the effective ways by which competitive advantage could be obtained in manufacturing industry. However, there exists a lack in effective management mode and decision-making engine about the reutilization of industrial waste at present. In view of this, under the framework of circular economy and green supply chain, this paper proposed a supply chain management model-interrelated supply chain based on the reutilization of industry waste. The following is the gained research results.â‘ Studied on the concept connotation, architecture and economic characteristic of interrelated supply chain, the three operational modes were proposed to realize performance of interrelated supply chain.â‘¡Studied on the problems of production cooperation condition and decision making optimization, the decision making optimizing model was proposed.â‘¢Studied on the coordination mechanism of production cooperation in interrelated supply chain, the method of realizing decision making coordination in interrelated supply chain was proposed.The above research results can provide a sort of management mode and decision-making reference for the reutilization of industrial waste from micro-level view, and to help manufacturing industry facing the grim market game in current severe situation of resource and environment and therefore obtain the competitive advantage by means of the value realization of waste reutilization.Firstly, the connotation of interrelated supply chain was defined and the architecture of interrelated supply chain was put forward. Furthermore, through the economic analysis of constructing interrelated supply chain, the problems and obstacles of constructing interrelated supply chain were revealed, and the key influencing factors of performance of interrelated supply chain were also revealed, and also the suggestions were put forward.Secondly, on the basis of the results of economic analysis and the features of constructing interrelated supply chain, and the case of interrelated supply chain management in practice, three kinds of operation mode of interrelated supply chain were put forward, and the characteristic, applicable conditions, optimal performance aim, key problems of various modes were deeply analyzed. Additionally, in order to verify the reasonableness and practicability of the research results, we carried through the typical case study of Guitang Group, Yili Resource Group, Chongqing Iron & Steel Group and Chongqing Lafarge Group.Thirdly, considering that there exist different conditions of wastes supply and demand in the operation of interrelated supply chain and different matching degrees of the wastes supply and demand have different effect on the performance of the interrelated supply chain, the independent decision-making model and the joint decision-making model of two core enterprises of interrelated supply chain were established. According to the model solution, the different waste supply and demand, the quantificational conditions and the output and price strategy of main product under the above conditions were given. Research results suggest that when waste supply is far less than demand, the cooperation space of system profit and main product output do not exist. When waste supply is far greater than demand, the cooperation space of main product output of downstream supply chain could reach the maximum, and the cooperation space of system profit is rather large. When waste supply is almost equal to demand, the cooperation space of system profit and main product output of upstream supply chain would be the largest, and the cooperation space of system profit also would reach the biggest.Fourthly, considering the leader-follower market behavior in the wastes supply relationship, Stackelberg model between the two core manufacturers was built up. And then, what we demonstrated the cooperation mechanism based on Stackelberg model was unreasonable and we explored the benefit conflict between the two core manufacturers. Furthermore, the coordination mechanism based on Nash negotiation model was put forward for reusing wastes fully and gaining economic income as much as possible.Finally, industrial waste is a kind of additional resource produced by the process of product production, so it is difficult to obtain the key information about wastes reuse value for the producer, such as its reuse cost and the market prospect of the product produced by reusing it. Therefore, applying the theory of principal-agent, we built up the trading game model between the waste supplier and reusing manufacturer. Additionally, we studied on the characteristics and efficiency of optimal trading contract of adverse selection so as to get an incentive to reuse waste at the furthest. The research results show that a group of separating contracts menu manner based on price & quantity is suitable for avoiding adverse selection, and improving the trading efficiency and making full use of industrial waste.
