考虑碳排放的铁路物流储运一体化方案优化模型OA

In the context of green development and market-oriented reform of railway logistics,providing customers with integrated and green warehousing,transportation,and comprehensive logistics services is one of the important reform directions for railway logistics enterprises.Drawing on the research results of carbon emissions in the field of transportation and logistics,this paper proposed a carbon emission calculation method for railway logistics service,considering transportation,warehousing,loading,and unloading operations under different energy consumption types.The logistics cost and carbon emission cost of the railway storage and transportation integration scheme were used as dual objective optimization functions,and a weighted standardization method was adopted to establish the overall objective function.Considering the requirements of rail-road intermodal transportation and delivery time limit,a railway logistics storage and transportation integration scheme optimization model that included carbon emissions was constructed.By simulating and verifying the scientificity and applicability of the model,the research results show that reducing the number of rail-road intermodal transportation changes has a significant impact on reducing carbon emissions.By coordinating the planning of arrival time windows and railway transportation schemes,the total logistics costs can be effectively reduced.
