PROBLEM TO BE SOLVED: To provide a compressor operation control system which can improve overall operation efficiency of a plurality of compressors in which at least one is different in an operation efficiency characteristic to the other. SOLUTION: A unit number control panel 30 executes operation control according to an operation priority table when feeding air by making the operation priority table of setting a compressor for performing operation among compressors 11, 12, 13 and 14 and operation priority of the compressor for performing the operation in response to respective 24 divided time zones based on respective efficiency curves of the compressors 11, 12, 13 and 14 different in the operation efficiency characteristic and an estimated required air feeding quantity Qn to an air demand apparatus 52 of a factory 50 with every 24 divided time zones by dividing one day into 24 time zones with every one hour.
