Integration optimization of sustainable supply chain network in railway construction
摘要
Abstract
With the increasing attention given to the sustainable development of railway construction projects,it is an urgent need for us to apply some advanced and integrated optimization theory and method for supply chain network design to improve the efficiency,sustainable performance,and resource utilization of the supply chain.To design a sustainable supply chain network was a significant way to realize the sustainable development of railway projects,in which the selection of suppliers,location of logistics facilities,route planning,inventory management,and recycling of waste were the core and critical issues of railway construction supply chain management.Based on the characteristics of the supply chain management of railway construction in China,an integrated optimization model for the sustainable supply chain network design of railway engineering construction was proposed.Meanwhile,the corresponding two-stage solution framework was proposed.In the first stage,the fuzzy TOPSIS method was used to determine the best supplier selection according to the sustainability index system.While in the second stage,the multi-period,multi-objective supply chain network integrated decision optimization model was given,which was based on fuzzy programming,to determine the optimal logistics facility location,inventory control strategy and optimal flow assignment among the supply chain network.The above optimization model aimed to minimize the total cost,carbon emissions,and maximize social benefits of the supply chain with the uncertainties of the transportation process.According to the characteristics of the proposed optimization model,an improved forbearing stratified sequencing method was given.Finally,a case study on the Fengxiongshang Railway Project in China was conducted to verify the effectiveness of the above solution framework and algorithm.The sensitivity analysis of three key parameters,namely unit freight rate,unit transport carbon emission,and disposal rate,was conducted.The results of the study are shown as follows.(1)The strategy of bulk discount benefits greatly in saving the purchasing cost by joint purchase method of purchasing.(2)The selection of transport mode and routing optimization show significant impact on the efficiency and sustainable performance of the whole supply chain system.(3)To promote the use of new energy sources is the most effective method to reduce carbon emissions compared to managerial measures.(4)The improvement of social benefits inevitably requires higher costs,and rational initiative subsidy policies of authorities are crucial to enhance the motivation of enterprises.(5)In the long run,waste recycling in the construction industry will become an important method,moreover,and its corresponding technology and application should be emphasized.关键词
