季节性运输波动下山区铁路工程弃渣回收物流网络优化
Optimization of logistics network for railway construction waste slag recycling in mountainous areas under seasonal transportation fluctuations
摘要
Abstract
The high proportion of bridges and tunnels in railway construction in mountainous areas of China,as well as the large amount of engineering waste,make the reasonable disposal and utilization of huge amounts of waste a key issue that urgently needs to be solved for the sustainable development of railway construction.However,seasonal factors can have an impact on the material transportation capacity and freight rates of railway construction in mountainous areas.Based on this,considering the seasonal fluctuations in transportation capacity and freight rates,as well as the uncertainty of waste residue output,this paper studied the optimization problem of waste residue recovery logistics network in mountainous railway construction,and constructs a multi-objective optimization model for multi cycle and multi product waste residue recovery logistics network.This model comprehensively considered the economic and social environmental benefits of logistics networks,optimizes and determines the site selection and investment construction scale of waste residue processing plants,procurement and waste residue recycling ratio,waste residue transportation route planning and flow distribution,and uses Epsilon constraint method to transform and solve the model.Finally,taking the Changgan Railway project as an example,the effectiveness of the model was verified.Analyze the solution results from the perspectives of multi-objective balance and seasonal impact.And conduct sensitivity analysis on the procurement prices and freight rates of the mechanism sand market.The research results are as follows.(1)within the range of high social and environmental benefits,the recycling and utilization of waste residue can help improve the economic benefits of the network.(2)The recycling and utilization of waste should mainly be arranged in autumn,and when the freight rate increases,the waste recycling behavior from other seasons can be transferred to autumn to reduce the total logistics network cost.(3)The government can intervene in the procurement and transportation markets through policy issuance to control the level of network carbon emissions,mainly by controlling the increase in autumn freight rates to avoid a sudden increase in autumn carbon emissions.The research results can provide effective reference for optimizing the logistics network of waste recycling and utilization in railway construction in mountainous areas of China.关键词
