The Research On The Optimization Of The Key Nodes Of The Tobacco Supply Chain

China's tobacco market is the biggest one in the world, and the tobacco industry ranks No. one in generating China's national fiscal revenue. After China's entry into the WTO, China's tobacco market has become a profitable one for powerful countries to compete in. Nowadays, it is widely believed that China's tobacco industry is solid in capital and flexible in autonomy. Given such environment in which there is seemingly not much room for optimization, these issues—how to further improve its productivity, efficiency, competitiveness—have become an important research subject in tobacco industry. From the perspective of supply chain, this paper explores the three traditional taches, i.e. procurement, production, and distribution of tobacco, for the purpose of key-node optimization, resource allocation and integration and to increase cost control and holistic competitiveness of the supply chain in our tobacco industry and facilitate the transformation from a tobacco country big in size to one competitive in market.Firstly, this article depicts the main business flows of tobacco supply chain, and analyzes the main problems existed in the tobacco supply chain.Secondly, by analyzing the present situation of procurement supply chain of tobacco enterprises, this article puts forward the procurement business process reengineering and procurement supply chain of tobacco enterprises based on the supply chain management. Also in this section, the discussion of the selection of tobacco enterprise supplier is strengthened, and such aspects are explored: set up the mixed orders allocation model of tobacco leaf procurement of tobacco enterprises, and put forward the heuristic algorithm of mixed orders allocation, based on the three basic operations of inner replacement, inner-external replacement and access or rejection.In the third section, these areas are discussed: set up the network chart models and dynamic programming models of production of tobacco filament according to the characteristics of the production of tobacco filament; optimize the production scheduling using the dynamic programming method and put forward methods for the model solution; set up network chart models for the storage tanks equipment quantity for the production line of tobacco filament, reach the solution method for the models and operation examples, research the dispatching optimization of multi-machines and multi-request of the automatic guided vehicle (AGV) system, and put forward responding models, also provide heredity algorithm for solving it, determine the one-one correspondence of request and AGV, fulfill the overall dispatching optimization of the integral AGV system, provide the desicive support for improving production capability and reducing production cost.Finally, taking into account the industry's characteristics such as monopoly sales and market dominance, program the network structure of hierarchy tobacco sale and distribution in the service scope of tobacco monopoly beaureau in China, analyze the influencing factors for site selection of tobacco sales-distribution center, put forward the evaluation index for effecting the distribution center, build fuzzy clustering evaluation model, solve the problem of the selection of distribution center, optimize the sales network structure of tobacco according to the principle of minimum cost, and allocate the service scope of distribution center, and optimize the distribution route, design the tobacco distribution networks, using the design of Hunan provincial tobacco distribution network as a case in point.
