floating scheduling

A method for scheduling preventive maintenance work that schedules the execution of a preventive maintenance procedure according to the completion date of the last preventive maintenance work request, rather than the scheduled execution date. For example, suppose you set a preventive maintenance procedure to be executed on the first day of each month, so that a job is due January 1. However, because of a holiday, the work is not completed until January 3. With floating scheduling, the next due date for the procedure is February 3 (one month from the actual completion date) instead of February 1 (one month from the scheduled execution date). Compare fixed scheduling.
