D医药连锁企业配送路径优化研究

Optimization of Distribution Path of D PharmaceuticalChain Enterprises[Abstract]D pharmaceutical chain enterprises as one of the largestpharmaceutical chain enterprises in Zhongshan City,the number of chain stores morethan 150,covering the entire Zhongshan City.With the continuous development ofenterprise scale,the original manual completion of vehicle path planning and vehiclescheduling can not meet the needs of enterprise development,how to choose ascientific and reasonable vehicle distribution route is an important problem thatenterprises must face at present.Based on the research object of D pharmaceutical chain enterprises,this paperanalyzes the current situation and existing problems of vehicle route distribution.Firstof all,this paper collates and introduces the related theories of vehicle path problemand medical logistics,and comprehensively expounds it.Secondly,this paper analyzesthe current situation and existing problems of pharmaceutical logistics distribution inD enterprises,analyzes and compares the principles,steps and other contents ofvarious algorithms and according to the actual distribution situation of enterprises,finally chooses the mileage saving method to construct the mathematical model,andthe store drug demand and vehicle nuclear load capacity are the constraints.Finally,by collecting the basic data related to distribution,the model and data are importedinto MATLAB software tools to solve,and finally the optimization results areobtained.The optimized distribution scheme can significantly reduce the cost oflogistics distribution and improve the economic benefits of enterprises.[Keywords]medical logistics distribution;path optimization;mileage savingmethod
