An Empirical Study On Urban Distribution Line Optimization

With the continuous expansion of city size and socio-economic sustaineddevelopment, logistics and distribution in the socio-economic status is an increasinglyimportant. urban logistics distribution as a branch in the logistics field, with thelogistics of the role and status of a sharp rise, and its importance has become moreprominent, deeper theoretical and practical research on city logistics is extremelyurgent, especially in urban goods distribution needs increase, more diverse types ofproducts, increase the frequency of delivery of goods, the urban road network is morecomplicated changing, increasingly stringent traffic control case. Urban goodsdelivery vehicles line optimization algorithm to take appropriate science andcutting-edge software applications of today’s logistics and distribution areasTransCAD platform, delivery vehicles in accordance with the set of optimizationgoals, scientific and reasonable delivery routing to reduce logistics costs improve theefficiency of delivery and then play an active role in the traffic environment of thecity is of great significance.Urban distribution showed a wide distribution area, the number of customers, thevariety of delivery of goods, distribution of high frequency and complexity of theurban road environment characteristics, the main job of city delivery routeoptimization as follows:(1) on the distribution of Guiyang City, the overall analysis, such as urbandistribution environment (including the road environment, market environment andecological civilization in the environment, etc.), Guiyang City distribution involvesthe supply and demand side, and Guiyang City, the implementation of thecharacteristics of urban distribution.(2) The urban distribution of the two sides to do a thorough and meticulousinvestigation, and I participated in the past mentor the various issues, has made aseries of important research data. In this paper, the urban distribution of the demandside of the city’s major retail customers (in Guiyang City, for example, data sourcesGuiyang tobacco companies, tobacco retail customer data); distribution party is themajor wholesale market in the city (data from the subject "of Guiyang City uniformdistribution of the survey). In the city’s major wholesale market as a distribution ofstarting point, the city’s major retail customers as the end of the distribution service.(3) The urban distribution lines arrangements to take the two-phase solution. First partition on the city size of the large number of retail customer outlets, in orderto reduce the workload and improve the effectiveness of the work; partition specificand effective distribution line for each partition within the retail customer outlets andThe sequence arrangement of distribution customers in this process takes fulladvantage of the various functional modules of the TransCAD platform.(4) In the arrangement of distribution line work is done to partition the internalnetwork of retail customers, according to the reality of the customer sequenceadjustment, such as the delivery of some customer service priority is relatively high,this is when you need to give priority to such customers delivery time.
