Operating method for a production line for rolling a strip, - wherein an actual value G and a setpoint value G* for the first strip point, a number of second strip points and a number of third strip points of the strip are known in each case to a control computer for the production line at the latest at a time point when said first strip point of the strip is still situated in front of the production line, - wherein the respective actual value G is characteristic of the actual energy content of the respective strip point (12, 13, 13') and the respective setpoint value G* is characteristic of the setpoint energy content of the respective strip point (12, 13, 13'), this applying to each strip point (12, 13, 13'), - wherein the respective actual value G relates to a location xE in front of the production line and the respective setpoint value G* relates to a location xA behind the production line, this applying to each strip point (12, 13, 13'), - wherein the third strip points are fed into the production line before the first strip point, characterised in that the second strip points are fed into the production line after the first strip point, - wherein the control computer determines a command variable L* in each case for the first strip point and at least a subset of the second strip points on the basis of a determining rule that is specific to the respective strip point (12, 13) and before the first strip point is fed into the production line, - wherein the respective command variable L* is characteristic of the command speed vL at which the control computer operates the production line at the time point when the respective strip point (12, 13) is fed into the production line, - wherein the control computer determines the respective command speed vL on the basis of the command variable L* that has been determined for the respective strip point (12, 13), and operates the production line at the respective command speed vL at the time point when the respective strip point (12, 13) is fed into the production line, and - wherein the actual value G and the setpoint value G* of the strip point (12, 13) currently entering the production line at this time point, and the actual value G and the setpoint value G* of at least one strip point (12, 13) that has already entered the production line at this time point, are input into the determining rule for the respective command variable L*. - wherein an actual value G and a setpoint value G* for the first strip point, a number of second strip points and a number of third strip points of the strip are known in each case to a control computer for the production line at the latest at a time point when said first strip point of the strip is still situated in front of the production line, - wherein the respective actual value G is characteristic of the actual energy content of the respective strip point (12, 13, 13') and the respective setpoint value G* is characteristic of the setpoint energy content of the respective strip point (12, 13, 13'), this applying to each strip point (12, 13, 13'), - wherein the respective actual value G relates to a location xE in front of the production line and the respective setpoint value G* relates to a location xA behind the production line, this applying to each strip point (12, 13, 13'), - wherein the third strip points are fed into the production line before the first strip point, characterised in that the second strip points are fed into the production line after the first strip point, - wherein the control computer determines a command variable L* in each case for the first strip point and at least a subset of the second strip points on the basis of a determining rule that is specific to the respective strip point (12, 13) and before the first strip point is fed into the production line, - wherein the respective command variable L* is characteristic of the command speed vL at which the control computer operates the production line at the time point when the respective strip point (12, 13) is fed into the production line, - wherein the control computer determines the respective command speed vL on the basis of the command variable L* that has been determined for the respective strip point (12, 13), and operates the production line at the respective command speed vL at the time point when the respective strip point (12, 13) is fed into the production line, and - wherein the actual value G and the setpoint value G* of the strip point (12, 13) currently entering the production line at this time point, and the actual value G and the setpoint value G* of at least one strip point (12, 13) that has already entered the production line at this time point, are input into the determining rule for the respective command variable L*.
