Distribution path optimization of zhongshan dashenlinchain drugstoreAbstractThis dissertation takes DaShenLin chain drugstore inZhongshan as the research object.During the internship in the company,obtainspecific distribution data,including warehouse data,distribution planning,distributiontime,distribution volume,etc..According to its current distribution status,the middlemay exist problems.In order to avoid the influence of model data on the results in thesolving process,the average demand of distribution stores is scaled up to obtain thevirtual demand,which is consistent with the comparison terms in the total distribution.With the optimization target,in order to get the shortest delivery route for thecharacteristics of the problem and algorithm optimization efficiency consideration,choose the single objective genetic algorithm model,and use MATLAB7.0 softwareoptimization solution,end up with a total journey in distribution and delivery vehiclesquantity project scheme is better than the physical distribution,the optimizationresults in theory to better improve the distribution efficiency and reduce logisticscosts.Keywords Pharmaceutical logistics Pharmacy chain Path optimizationGenetic Algorithm
