| As a core component of the logistics industry chain,the "last mile" distribution link of urban logistics plays a key role in meeting residents’ logistics distribution needs and improving residents’ happiness index.The "last mile" distribution link of urban logistics has significant unsustainable characteristics,such as high costs and labor shortages due to aging populations and fewer children,exhaust emissions and noise pollution from transportation vehicles using traditional energy sources,traffic congestion and personal safety issues caused by irregular driving of distribution personnel,and solid waste and garbage recovery issues caused by logistics distribution resource consumption.The above issues violate China’s sustainable development concept and the industry trend of intelligent transformation in the logistics field,providing an objective basis for this article to explore intelligent unmanned delivery vehicles under the sustainable concept.Starting from the theoretical research on sustainable concepts and intelligent distribution,this article combs out the pain points in the "last mile" terminal distribution process,proposes the expected goal of "three low,two high,and one optimization" of intelligent distribution vehicles enabling urban logistics,deduces a multidimensional context with distribution,pickup,and feedback as the main process nodes,and constructs a context based design and evaluation model for intelligent unmanned distribution vehicles,Some functions of the intelligent unmanned distribution vehicle were optimized,such as the UV disinfection and sterilization function under the public health security requirements in the post epidemic era,and the design concept of module "X" suitable for multiple scenarios was proposed in the distribution vehicle scheme practice.On this basis,the feasibility and effectiveness of the design scheme are evaluated and verified.Intelligent unmanned delivery vehicles mainly embody sustainable design concepts in terms of reducing labor costs,making up for labor shortages,reducing environmental pollution,alleviating energy consumption,using biodegradable materials,and optimizing resource allocation,with a view to contributing innovative,practical,and practical design solutions to the "last mile" of urban logistics,Further,it provides some reference significance for the relevant research on the intelligent transformation of urban logistics and the sustainable development of terminal logistics. |
