Research On Simulation And Design Optimization Of The Tobacco Order Picking System

Tobacco logistics distribution center for its advanced automation, large-scaledistribution system in the forefront in all sectors of logistics, reflects the highest level ofdevelopment of automated distribution center.Tobacco tobacco distribution center sorting system is the most important part of the coreoperations, improve sorting efficiency sorting system has a very important significance toimprove the operating efficiency of the distribution center.Tobacco sorting system with latency and sorting system previously studied significantlydifferent characteristics, in particular to optimize the core target object by the shortest routeinto and from picking and replenishment of resources does not lead to timely release of theshortest, and its string parallel combination of tree-partitioning scheme greatly improves thecomplexity and difficulty of the system studied.The storage spaces allocated using the method of combining the path, the mathematicalmodel of the various aspects of the sorting system, pointing out the possibility that the sortingsystem deadlock phenomenon. Handan tobacco distribution centers and automated sortingsystem, for example, tobacco sorting mechanism for sorting system is described in detail,and pointed out the Handan tobacco distribution center for the prevention of deadlock andestablish a sort of deadlock prevention strategy this strategy resulted in the same time usingthe sorting efficiency decreased to some extent.The establishment of a numerical experiment tobacco sorting system simulationprogram, the program to sort chronological order, including customer order splitting andrecombination, Subpart Cigarette sorting links, pieces of tobacco packaging and palletreplenishment links and links, etc. interlocking, mutual restraint, in the center of the smokesorting links to a number of parallel sorting line of smoke chronological order, replenishmentand resource release cycle to determine the situation on the downstream and upstream step bystep to their respective send link replenishment requests. Pointed out that as a result ofcustomer orders with strong randomness and uncertainty, the distribution is very irregular, global optimization algorithm is not able to design problems of internal tobacco sortingsystems to optimize the parameters.Through simulation analysis, the definition of the replenishment delay factor Bby usedto quantify the degree of influence various aspects of reality is difficult to determine thenumber of structural parameters on the total time sorting extended. And as a basis todetermine the optimal design parameters of replenishment aspects need to meet the conditionsfor the realization of the work to be completed as soon as the goal of sorting tobacco sortingsystem optimization analysis provides a basis for the design and basic methods. And strategiesand conclusions drawn series designed to help tobacco sorting system.
