PURPOSE:To improve the productive efficiency of the whole line by detecting bottle neck processes from pitch time and determining the use assignment of production unit group for this process to drop the pitch time for the bottle neck process. CONSTITUTION:Actual result time in respective production processes 5a-5c is input and the input actual production result data are temporarily stored in a actual production result storing section 1b. On the basis of said data thus stored, and production process having the maximum pitch time, together with a pitch time calculation section 1a for figuring out pitch time (time interval of attained actual productive result) at respective production processes 5a-5c is determined as a bottle neck production process on production (bottle neck process detecting section 1c). To drop the pitch time to the bottle neck production process, the production equipment 7 for this process is assigned to the preparatory operation for redistribution, removable attachment of workpiece and mounting the exchange of jig tool set in response to the operative amount by article type groups.
