The invention discloses a fair-share scheduling method for multiple processes of computer. The method comprises the following steps: 1, selecting processes from a process set to form a scheduling set, and a reserved scheduling queue is formed by the unselected processes; 2, determining whether the requirement of a process scheduling is over or not, if the requirement of the process scheduling is not over, the next step is conducted, or the scheduling is over; 3, scheduling the scheduling set; 4, conversionring the scheduled processes in the scheduling set to the tail of the reserved scheduling queue; 5, emptying the scheduling set; 6, selecting processes from the reserved scheduling queue to form a scheduling set and jumping to step 2. According to the fair-share scheduling method for multiple processes of computer, the scheduling set of the processes and the reserved scheduling queue are formed by the operation of set computation, so that the fair-share scheduling on computer multi process is achieved, the occurrence of deadlock during the concurrent scheduling of the processes is avoided, and the scheduling ability on concurrent processes of the computer processor is improved.
