Research On Quality Control And Path Optimization Of Fresh Products Cold Chain Logistics Distribution

With the development improvement of people's living standard,people pay more and more attention to quality of fresh products.Because there is product loss and high distribution cost in the process of fresh product cold chain logistics distribution,it is difficult to guarantee fresh product quality.Therefore,it is an important research problem to control quality and improve the distribution with reasonable path in the process of fresh product cold chain logistics distribution.Based on the analysis of the current situation of fresh product cold chain logistics distribution,the article focuses on quality control and path optimization in fresh product cold chain logistics distribution.In the research of fresh product cold chain logistics distribution quality control,due to diverse and changeable the customer demand,it is necessary to continue to survey customer needs and satisfaction for demand.Based on it,control and improve the quality of fresh product cold logistics distribution.The article construct a model of cold chain logistics distribution quality control and improvement process based on QFD and PDCA.First in the P phase,Obtain customer requirements and initial importance,then and use the Kano model and market competition assessment to revise the initial importance of customer demand with the correct factor,and determine the quality control factors of the customer demand influence,and establish the autocorrelation matrix of the control elements and the correlation about customer needs and quality control elements,and ultimately determine the ranking of the enterprise quality control elements with the customer needs mapping for the quality control elements,and thus determine the improvement target and formulate improvement measures through finding out the key control elements.In the D phase,go on the implement.In the C phase,check the effect of measures.In the A phase,continue and optimize the measures.Then the paper studies the distribution route optimization.In order to minimize the total distribution,analyzes the elements of distribution costs,including: vehicle fixed cost,transportation cost,refrigeration cost,damage costs and the penalty cost which is related to fresh products fresh degree function.On this basis above,build the optimization model of fresh products cold chain logistics distribution route with time window and use the tabu search algorithm to solve the model.Finally,the paper goes on example analysis combining with fresh products cold chain logistics distribution of the specific enterprises to verify the effectiveness and feasibility of the method.
