A method and a system for scheduling apparatuses in a production line are disclosed. Each of the apparatuses on the production line includes one or more functional modules, each of the functional modules have a task sequence, and a task sequence includes one or more tasks. The method includes: obtaining a queuing time required for executing each of the tasks in the task sequence of the functional module; identifying a task that has a shortest queuing time in the task sequence as a target task; executing the target task; removing the target task from the task sequence and obtaining an updated queuing time required for executing each of the tasks in the task sequence. The method divides the apparatuses on the production line apparatus into a plurality of independent functional modules and executes the task having the shortest queuing time first with respect to each of the functional modules. It can be guaranteed to minimize an overall queuing time for each of the functional modules of the apparatuses on the production line during the scheduling process. Therefore, the scheduling efficiency can be increased.
