Research On Distribution Path Optimization Of Dairy For The K Cold-chain Logistics Company When Considering Carbon Emission

With the rapid development of China's economy and people's consumption level unceasing enhancement,people's demand for dairy products is more and more strong,it also promotes our country cold chain.But because the dairy's own features,storage transportation of dairy products require preservation,refrigeration.To maintain high quality of dairy products in the whole process of transportation,transportation vehicles must be equipped with relevant refrigeration preservation equipment.These devices are usually large energy consumption and high carbon emissions,along with the social low carbon action of promotion,cold chain transportation energy conservation and emissions reduction is the trend of the times.In response to national advocacy of "low carbon economy",must optimize the current dairy products cold chain transportation.This article is both at home and abroad of low carbon logistics,cold chain logistics and cold chain logistics vehicle routing problem on the basis of existing research results,around the K cold-chain logistics company.First of all,this paper expounds the thinking of carbon emissions of dairy products cold chain logistics distribution problem related to cold ch ain logistics,low carbon logistics,vehicle routing problem related theory.Secondly,the paper analyzes the current situation of K cold-chain logistics company logistics distribution,in view of the problems such as unreasonable distribution route planni ng,combined with the development of low carbon environmental protection concept,the minimum total distribution costs and the highest satisfaction as the optimization goal,with rated load of the refrigerated trucks,store window as constraint conditions,such as the stipulated time,single distribution center is established considering carbon demand more dairy products with soft time windows constraint cold-chain distribution route optimization model.Again,using the improved genetic algorithm to design to solve the model.Finally,using the MATLAB software to K cold-chain logistics distribution route model for data analysis and solving,on the problem of carbon emissions,with the consideration of carbon emissions and does not consider two kinds of experiments,two different cases of the optimal path.After comparison and analysis,draw the conclusion: under the condition of considering the carbon distribution of total cost has been reduced,total length distribution route is also reduced,and carbon emissions are greatly reduced.Therefore,consider carbon emissions of dairy products cold chain logistics distribution path optimization,not only can reduce the distribution costs of the enterprise,but also can effectively reduce carbon emissions.Through t he research work of this article,and ultimately improve the K carbon emissions in the process of cold chain logistics company distribution and distribution costs,for cold chain logistics enterprise also has a certain reference and reference,in the curre nt under the background of carbon neutral,carbon amount to peak,early low carbon distribution layout,can reduce the environmental cost of enterprise,makes the distribution more environmental economic path.
