A control method and a system for dispatching the execution sequence of the processes in a multiprocessors system so as to dispatch an operation sequence for executing different operation programs by a monitoring processor and a plurality of target processors. The monitoring processor obtains operation status of other processors from a buffer; the monitoring processor selects at least one target processor according to the operation status; the monitoring processor assigns the target processor to execute a corresponding slave operation program, and modifies the operation status of the target processors in the buffer module; and the monitoring processor repeats the setting the operation status and assigning other target processors to execute corresponding operation programs, till a master operation program is completed.
