多维视角下建筑废弃物减量化系统物流网络设计

Logistics network design of construction waste reduction system based on multi-dimensional perspective

针对建筑废弃物循环利用不足的问题,讨论了具备现场处理能力与否两种条件下建筑废弃物减量化系统的物流网络设计方案.以系统中各参与方的功能及相互关系为基础,以实现经济、环境和社会三个维度可持续发展为目标,建立了减量化系统的物流网络模型;以成都市为例,对该区域建筑废弃物减量化物流网络进行优化重构.研究表明:建筑废弃物经过减量化处理,系统总成本降低;建筑废弃物资源化能力保持不变时,提高建筑废弃物再回收比例,系统的经济效益和环境效益相应改善;提升建筑废弃物资源化能力,系统的经济效益和环境效益也相应改善.

To improve rational reusing and recycling of construction wastes,we discussed the logistics network design problems of two kinds of building waste reduction systems-with or without on-site processing conditions.According to the functions and interrelations of all participants in the system,a logistics network model of reduction system was established to realize the sustainable development of economic,environmental and social dimensions.Taking Chengdu as the research object,the logistics network of building waste reduction was conducted with optimal reconstruction.Results showed that the total system cost was reduced after the construction waste reduction.The recycling ability of construction waste was increased to improve economic and environmental benefits of the whole system.On the contrary,the ability of construction waste resources and the economic and environmental benefits of the whole systema are positively correlated.
