The present invention discloses a system for realizing order management and control, a method for realizing order management and control, a scheduling server and a processing server system. The method includes the following steps that: when a scheduling system determines that order tasks need to be issued, the order tasks are issued, and the number of the issued order tasks is counted through a first counter; and when the scheduling system learns that the issued order tasks have been successfully processed, the number of the order tasks that have been successfully processed is counted through a second counter. According to system for realizing order management and control, the method for realizing order management and control, and the scheduling server and the processing server of the invention, when a scheduling decision in the scheduling system determines that the orders can be issued, pre-counting is performed for once, namely, the value of the first counter adds one, and therefore, management and control on the issuing of the orders by the total scheduling of the system is realized really; and therefore, when the scheduling system makes scheduling decisions on other orders subsequently, the scheduling system can refer to the value of the first counter so as to determine whether the number of orders issued to warehouses exceeds the capacity of the warehouses timely, and therefore, precise control on order issuance on the basis of a distributed system can be ensured, and the problem of inaccurate control caused by asynchronous time difference can be avoided.
