The invention relates to an AGV quantity and work task matching method in an AGV production scheduling system. The multi-track interactive AGV production scheduling system comprises multiple work stations, multiple AGVs and multiple operation tracks, various types of information in a production process are interacted, a present work task and an operation line are selected by each AGV in the operation process according to an instant system state, and system complexity and AGV decision instantaneity make the AGV quantity and the work tasks be difficult to pre-match reasonably. Through the method, a system operation state can be pre-simulated, required AGV quantity can be pre-determined under the condition of certain work tasks, bearable largest work tasks can be determined under the condition of certain AGV quantity, required work time can be pre-determined under the condition of the certain AGV quantity and the certain work tasks, and thereby the work tasks and the AGV quantity can be reasonably matched.
