Research on Simulation and Parameters Optimization of Kanban Production System Based on Witness

Based on the basis theory of Kanban production system,the article takes an engine assembly workshop as an example,simulation and optimization about workshop Kanban production system are done by using the Witness software,which will predict the implementation effectiveness timely.And the evaluation towards system performance can be given,such as the equipment utility rate,the effectiveness of order processing et al.The result shows that Kanban production system implemented after,the order gets timely response,the customers' satisfaction is improved,the equipment utility rate and the production efficiency are improve obviously,meantime,the product output reach target yield.Finally,the recessive parameters of Kanban production system are optimized.It will provide a basis for different enterprises implementing Kanban production system according to practical product condition.
