Procedure The scheduling of maintenance work involves essentially two steps.

Considering total man hours needed for each task segment and the manpower available, the distribution of jobs (that will give reasonable man loadings, and can be accomplished) is done.A master schedule is flexible and a cushion always exists to accommodate, unanticipated tasks and jobs which are lagging behind schedule. Detailed schedules are prepared by breaking overall time spans allocated under master schedule.

Detailed weekly work schedule provides information to each craft and shop regarding the task to be carried on each job for each day in the coming week.Detailed scheduling requires records of work capacity of each section of the maintenance department and of the maintenance department as a whole.

Like master schedule, the detailed schedule should also be flexible and able to accommodate emergency jobs.Detailed schedule may be issued to concerned persons every day or near the week end.

Maintenance schedule of each machine may be prepared and it will indicate the list of works which must be carried out (together with the frequency) and will contain servicing, adjustments, lubrication details and particulars of replacement work.
