Multi-objective Location Model Design And Game Playing Analysis For Recycling Based On Reverse Logistics Network Of CDW

With the acceleration of China's urbanization,China's construction industry is booming.Substantial accumulation of CDW(Construction and Demolition Waste)have a great negative impact on the environment and society,due to most of the CDW can be recycled,the reasonable recycling of CDW is very necessary.This paper analyzed the status of CDW recycling at home and abroad,summarized the status quo of the research in the CDW recycling in China,then studied the advanced experience and technology in terms of CDW recycling of developed countries,compared the gap between our country and developed countries,pointed out that there was obvious gap between our country and developed countries in the aspect of CDW recovery.After analysis of the types of CDW,the recycling and utilization of main CDW were described in detail.Based on the types and available degree of CDW,CDW shall be classified three types:Materials that can be reused for simple processing,materials that need to be remanufactured for use,and materials that are not available.This paper set up a recycling model which was in accordance with the classification of the construction and demolition waste.In this paper,the cost and recovery of reverse logistics network are both considered,and the reverse logistics network of CDW based on the cost-recovery ratio is established.Using the improved normalized-normal constraint method to solve the model,the pareto front is obtained based on the recovery and cost tradeoff.Considering the important role of the government in the reverse logistics network of CDW,the paper studied the game playing between government with dominant firm in the reverse logistics of CDW,and analyzed the sensitivity of the model.
