AUTO-CORRECTING PROCEDURE FOR THE OPTIMIZATION OF TURNROUND SCHEDULES OF MOTIVE POWER UNITS

Turnround schedules for motive power units are obtained using electronic data processing systems, from a solution of the problem of linear optimisation. While allowing for the prescribed reversal times of locomotives and for other operating requirements, the minimum locomotive standing times are achieved. The auto-correcting procedure makes use of certain reserves in the reversal times, thus enabling locomotive transitions, which are frequently only a few minutes too short, to be incorporated into the turnround, consequently leading to a considerable improvement of the turnround schedule. The reductions in reversal times required for this are already covered by the computer program during the establishment of the turnround schedule and recorded for the next program sequence, using amended data. The process requires several correction stages and it is terminated as soon as the shortest possible reversal time has been attained at a reversal station. The user can thus make a choice from a number of turnround schedules. Experience hitherto has confirmed that this procedure leads to optimum turnround schedules.
