Simulation And Optimization Of The Inventory Control System Based On Witness

With the globalization of the economic, the market internationalization and the integration, user's needs' individuality and the uncertainty as well as science's and technology's rapid development, the supply chain management, Especially the supply chain inventory management to be able particularly to reduce the reserve effectively, reduces the fund backlog, raises overall system's efficiency, the enhancement enterprise's competitive power, more and more has received people's widespread attention.Computer simulation technology particularly to discrete element simulation application, in the circumvention mathematical analysis method is insufficient in the foundation, can promptly effectively provides the policy-making basis for the system planning and the operation departmentThis article reviewed the supply chain management, the supply chain stock and the supply chain stock simulation three aspect research contents, introduced supplies chain's development, the definition, the research content, supplies management content which, control model, method, strategy the chain keeps in stock, supplies the chain stock simulation the present situation. Also to the computer simulation, the discrete element simulation and the Witness basic principle has carried on the introduction analysis, proposed based on the Witness emulation technique stock decision theory.According to the supply chain inventory system characteristic and the simulation goal, use Witness to supply the chain inventory system to carry on the model simulation, the movement to optimize, and proposed that supplies policy-making finally five synergies,makes every effort to describe and the solution supply chain stock question with the quota optimized method, for the enhancement supply chain efficiency, reduces the supply chain cost, to increase supplies chain's benefit to provide the basic theory and the method support.
