The Optimizer Research Of Fruit And Vegetable Cold-chain Distribution Path In Changchun

There are many nutritional value of the fruit and vegetable.The people’s dinningtable can’t lack of them.At present,more and more people pay attention to the qualityand the security of the fruit and vegetable. Unlike other products,the fruit andvegetable have a lot of unique factors,like seasonal factors,regionalfactors,perishability characters,timeliness characters and low value characters.Thefruit and vegetable circulation process needs cold chain technology to support it,tomake them in a suitable temperature and humidity to make sure of them quality andsecurity.Compared with the developed countries, the fruit and vegetable circulation inChina have a lot of problems. It lakes of logistics service concepts, base installations,laws and regulation standards, information technologies and so on. Leading to somany problems.Like owning the high cost,the low efficiency, the low satisfaction. Toimprove the fruit and vegetable cold chain logistics.It is important to need to besolved.In the fruit and vegetable cold chain logistics,the distribution is so important.Itowns the70%cost and80%time.So many researchers devote themself to solveit.Like building the model and optimizing the algorithm.The object of this article is optimizing the fruit and vegetable cold-chaindistribution path in Changchun.Depend on analysising Changchun fruit and vegetablecold chain logistics market,inductive the main problems of planning fruit andvegetable cold-chain distribution path.Then,Constructing the fruit and vegetable cold-chain distribution path optimizer model, to meet the request of the customer andrealize the lowest total cost.By comparing the advantages and disadvantages of allkinds of optimization algorithm, choosing the ant colony algorithm, ant colonyalgorithm in the distribution path optimization has the applicability of the naturalchoice, it also has stronger robustness, parallelism and positive feedback.Finally,putforward the optimizationg advices.Through the example calculation, proving thefeasibility and effectiveness of the model.Through optimizing the fruit and vegetable cold-chain distribution path,we can reduce the logistics cost,improve theefficiency,meet the customer request.
