Frozen foods are perishable, fresh food in cold storage under the new food is aproduct of economic development and technological progress. As to accelerate the paceof social and grade improvement of people’s lives, frozen food safe and efficientfeatures to make it more and more welcome, rapid increase in demand for frozen food.With the emphasis on the health, environmental protection, the standard diet fed fromthe original green, safe eating. Frozen food must show a trend of rapid growth.In order to reduce the distribution cost of food cold chain logistics. Firstly, theresearch status at home and abroad of food cold chain analysis, and then conducts theresearch to the development of food cold chain logistics in China problems. Then wesolve the cost optimization model is established and the model of the food cold chainlogistics and multimodal transport with time window. During the research process, fullyconsider the cost, transport process occurs mainly include: transport costs, transport thetransport costs of conversion, heat conduction loss distribution process cost, in violationof the restriction of time window which led to the penalty fee, ahead of the arrival of thestorage costs, energy loss cost, introducing the transport arrived the time window, thetransportation capability of the vehicle, vehicle driving changes in the process oftemperature constraints, On this basis, a nonlinear programming model, through theanalysis of advantages and disadvantages of the genetic algorithm, the genetic algorithmto calculate the local convergence problem often appears in the process, strong localsearch capability of simulated annealing algorithm, carries on the revision to the geneticalgorithm, in order to get the optimal solution. Through example analysis, through thecomparison of the food cold chain logistics and multimodal transport model and itsoptimization model of the transport costs, prove that the customers within the timeprescribed, multimodal transport modes effectively reduce early or late arrival distribution process arising from the penalty value, reduce distribution costs to.Through thorough analysis on Influencing Factors of food cold chain logistics andmultimodal transport cost, set up cost optimization model, provides the reference for thefood cold chain logistics enterprise time during transport and path selection. At the sametime also provide advice for the development of cold chain logistics.
