Research on the Urban Construction Waste Recycling Network and Its Optimization

This paper concentrates on the problem of urban construction waste recycling network optimization, and the main innovation of this paper is to introduce mixed integer programming in this problem. Firstly, the system layout of the construction waste recycling industry is proposed. Moreover, to construct an urban construction waste recycling network, we should formulate the rules of resource optimization and combination, determine the relationship between enterprises, and realize reasonable division of labor and coordination in advance. Secondly, an urban construction waste recycling network optimization algorithm is developed using the mixed integer programming, and three components are contained in our objective function. Finally, to make performance evaluation, we choose Chengdu city in Sichuan province to construct the dataset, and experimental results demonstrate that the proposed can effectively optimize the urban construction waste recycling network.
