To provide a servo press line operation method and an operation control device, capable of unfailingly preventing the generation of an interference and executing press operation with maximum productivity.

The servo press line operation control device is provided with: a normal press operation control means; a normal transfer operation control means; an upward movement step delay determination means; a downstream-side transfer step delay correction control means; an upstream-side transfer step delay determination means; a slide downward movement step delay correction control means. The servo press line operation control method performs a normal press operation for matching a slide position a to a target slide position s based on slide motion information, and performs a normal transfer operation for matching a transfer position Xa to a target transfer position Xs based on transfer motion information, and performs a correction for delaying a transfer step of a downstream-side servo transfer device 30D as compared with the normal transfer operation when a slide upward movement step is in a delayed state and performs a correction that delays a slide downward movement step of a servo press 30 as compared with the normal press operation when an upstream-side transfer step is in the delayed state.
