Abstract: With the development of intelligent manufacturing, automation of production line is improving. AGV (automated guided vehicle) as a necessary device in the automation system, it is important to design its charging system. Aiming at the problem of the site selection of online charging, the software FlexSim was used to build simulation model, based on the operation requirements of an actual assembly shop, in an actual planning process. Through a large number of simulation experiments, the maximum stay location of AGV in the different lines was obtained under the influence of random factors. By comparing the idle and blocked timebefore and after the location as an online charging site, the result shows that both of them are increasing and prove the suitability of selecting this point as an online charging site.

Key words: AGV, simulation, online charging, site selection
