Research On Stability Evolution And Evaluation Of Building Green Supply Chain

In recent years,excessive utilization of resources,environmental pollution and other problems increasingly restrict the sustainable development of the construction industry.In order to realize the industrialization transformation of building production mode,the green supply chain management mode gradually develops.Compared with the traditional building management model,green supply chain has advantages in improving the economic benefits of enterprises,optimizing the allocation of resources and reducing the negative impact of the environment However,the application of green supply chain management mode in the construction industry is not yet mature,mainly manifested in the core enterprise of supply chain lack of the understanding of the returns and risk of investment in new production relations,the simplification of green supply chain structure and dispersion,and green building products "externalities" factors such as the greening implementation of construction supply chain uncertainty.Therefore,this paper explores the game relations among different subjects and the internal and external shadow factors of the supply chain,analyzes the evolution conditions and evaluation methods of the stability of the building green supply chain,and provides references for the implementation and development of the subsequent building green supply chain.Firstly,based on the research background and significance,the necessity of implementing the green supply chain for buildings is analyzed.Combined with the research status of related fields at home and abroad,the research content,innovation and research methods of this study are further explained.At the same time,the related theories and methods used in this paper are sorted out to lay a theoretical foundation for the whole paper.Secondly,the main body and internal and external driving factors of the implementation of building green supply chain are clarified,and the construction of building green supply chain is deeply explored.Taking RDEU game and evolutio nary game as the research tools,this paper mainly analyzes the influence of the environmental state of the system and the effectiveness of the decision-making of the main body of the supply chain on the stability of the building green supply chain by constructing the game model of government regulation and the main body of the node,and makes a simulation analysis on the strategy selection and influencing factors of the main body of the game with MATLAB.It is found that under the framework of rankdependent expected utility theory,emotional factors have a significant impact on the game equilibrium between the government and green behavior participants,especially when the government is pessimistic or optimistic,the probability of green behavior participants in the supply chain will increase or decrease significantly.Will produce population,consumption and decompose the population into three subject within the framework of dynamic game,the evolution of the main body of green supply chain decisions are the result of the game each other stakeholders,by improving the participants’ green incremental earnings,future value perception,decrease the cost of green participation can make all the strategy of combination converges to a rational steady state.Finally,a single supply chain is extended to the supply chain network,and the stability evaluation of building green supply chain network is analyzed.The specific process is as follows:1)DS evidence theory and grey target theory are used to calculate the importance of nodes in the building green supply chain network,and the importance of nodes is ranked according to their importance degree,which is taken as the weight coefficient of importance of each subject;2)from the perspective of enterprises,consumers and government to build index system of green supply chain network stability,building green supply chain networrk by calculation of deviation degree of the decision-makers and similarity of cloud,build give a kind of uncertainty of the language a multicriteria evaluation model of cloud,form the concept of qualitative indexes and quantitative conversion between said,to get each node body stability evaluation results;3)expressed in importance weight coefficient to the importance of the supply chain network node subject,based on the main body stability evaluation results,calculate the stability of the whole building green supply chain network,and through the case analysis,the results of the comprehensive similarity and only consider distance similarity,shape similarity comparing with the results of analysis,to verify the effectiveness of the methods of this research,raise the scientific nature of the construction of green supply chain network evaluation...
