Modeling and simulation of Kanban production system on some engine assembly line

In view of low production efficiency for traditional production system on some engine assembly line,the modeling and simulation technology of assembly systems managed with kanban was studied.The Petri net model of production Kanban system was set up and converted in equivalent Markov Chain(MC),and the calculation formula of performance indicates was obtained.Witness software was used to simulate the model,and the result showed that the utilization rate of devices was increased greatly after implementing Kanban production system;the amount inventory of Work-in-Process was reduced,the production rate of assembly system was increased and the average delay time of unsatisfied orders was shortened.The influence of safety factor and variation coefficient on performance indicators of Kanban production system was analyzed,thus the different environmental adaptability of kanban strategy was mastered.
