Decision-making Research On Recycling Utilization Mode Of Construction Waste Based On Reverse Logistics

In recent years,under the guidance of the sustainable scientific development concept of ecological conservation,China has achieved high-quality social and economic development.However,with the acceleration of the urban construction process and the implementation of strategic planning for the revitalization of urban and rural areas,the scale of construction is still increasing year by year,and the amount of construction waste generated during the construction process is also increasing year by year.How to guide the construction of a scientific and rational construction waste recycling model has always been a hot topic and a difficult issue in academic research and practical application.This is not only the internal requirement of the government to promote ecological civilization to effectively solve the comprehensive utilization of construction waste,but also a realistic requirement for the sustainable development of construction companies.Firstly,on the basis of carefully reviewing the research status of construction waste recycling and reverse logistics modes,author combines the theory of reverse logistics with the recycling of construction waste.according to the technology of construction waste recycling and its operational flow,author will design construction waste recycling based on the RM,PM,TPM reverse logistics of the model operational flow;at the same time,after in-depth analysis of the mutual constraints,according to the guidance of grounded theory,author will establish a decision index system based on reverse logistics mode of construction waste recycling;Secondly,author will use the improved gray correlation method to obtain the weights of decision indicators;The use of improved GC-TOPSIS to propose a model decision-making model;author will the linear programming method of operational research,to the in-depth analysis of construction waste recycling reverse logistics model operation process,to build model operation simulation verification model.Finally,combined with case analysis,the proposed model decision-making model is calculated and analyzed,and the results of the decision-making are further verified based on the established model operation simulation verification model.The research results show that the decision-making model and simulation verification model of construction waste recycling model based on reverse logistics mode in this paper are feasible and reasonable.The methods used in the model can calculate the case data relatively accurately and simulate objectively.Out-of-the-mode operation flow to verify the accuracy of the decision results.This not only provides a theoretical basis for the construction enterprises to scientifically select the recycling mode of construction waste,but also the new construction waste recycling model for the construction process,effectively reducing project construction costs and minimizing the increase in construction waste due to construction.The negative impact of the ecological environment has brought new ways and methods.
