Abstract:

As a complete automated guided vehicle(AGV) system scheduling algorithm, it must include conflict-handling strategy, together with common dispatching strategy and routing algorithm. However, due to the uncertainty, characteristics of such scheduling algorithm are difficult to be analyzed theoretically, and the relevant study is lacking. AnAGV system simulation platform based on the discrete-event simulation technique is designed and developed, which can flexibly set the scheduling problem, choose the dispatching strategy, routing algorithm, and conflict-handling strategy for the scheduling algorithm, to run the simulation. The platform has a visual interface, from which the running status of AGVs and the performance of the scheduling algorithm can be intuitively observed, and it can also output statistical data of the simulation experiment. Experiment results show that the simulation platform can accurately and effectively evaluate and compare the scheduling algorithms in uncertain environment.

Key words: automated guided vehicle(AGV) system scheduling, uncertain environment, route conflict, discrete-event simulation, simulation platform
