Research On Optimizing Logistic Distribution Routing Problem For Y Medicine Chain Co.,LTD.

In recent years,due to the improvement of people's income level,people more and more attention to health,demand for pharmaceutical products is also increasing.As an important part of the pharmaceutical industry,medical logistics is facing severe challenges and opportunities.Faced with such fierce competition,to build scientific,efficient,rational medicine distribution system,the vehicle for a reasonable distribution route selection and optimization,not only to save distribution costs,reduce picking time,but also improve customer satisfaction It has very great significance.Fuxin Y Pharmaceutical Chain Co.,Ltd.is the first company in Fuxin pharmaceutical chain enterprises,chain stores covering the whole city,at present,the company is working on the distribution path selection work has not paid enough attention,choose the path often rely on personal habits and experience to complete the driver This increases the company's operating costs,is not conducive to long-term development,path planning unreasonable and unscientific also affected the carrying capacity of urban transport,and construction of the current advocates of resource-saving society contrary.Based on the above background,this paper will Fuxin Y Pharmaceutical Chain Co.,Ltd.as the object of study,the company in Fuxin County,10 chain stores,for example,analyzed its presence in the distribution path selection and optimization problems.First,this paper introduces the research status of the routing problem,leads to the concept of pharmaceutical logistics and distribution route optimization problems,introduce several route optimization research methods;Secondly,the problems currently faced by the distribution of work and to identify causes of the problem.Again,according to the company's actual work required to establish the same starting point and end point of time windows constraints,cycling field,non-loaded vehicle routing problem model,through the analysis and comparison of several algorithms for logistics distribution routing,and ultimately chose to take Time Window improved saving method to solve the model constructed.At the end of this paper,the use of MATLAB software written for an Improved procedures under the Conservation Act,path selection,in which the actual data into the model is solved to obtain the shortest path,that is the best route distribution program.The program will seek solutions and distribution route choice before company drivers often compared to find the model that we can really build effectively shorten the delivery company delivery vehicle driving distance,save delivery time and method feasible.
