PROBLEM TO BE SOLVED: To shorten the time necessary for reordering a plurality of processing objects by surely searching a processable one from the plurality of processing objects in a short time. SOLUTION: A storage means 101 stores a plurality of processing-waiting entries. In matrix information of a matrix means 102, each row number is related to the storage position of each entry in the storage means 101 and each column number related to the order of each entry, and an element corresponding to the storage position and order of each entry has a predetermined value. First vector information of a vector means 103 shows storage positions of processable entries. A control means 104 computes the first vector information and each column of matrix information to generates second vector information showing orders of the processable entries. An order to be processed is selected from the orders shown by the second vector information, and an element having a predetermined value in the column corresponding to this order is determined, and the entry of the storage position corresponding to this element is processed.
