What Is Operator Time Off in Scheduling? EDGEBIC Definition

Operator time off is a leave, PTO, or training date range recorded against one operator that removes their hours from the labor pool for those days, inclusive of both ends. It is the people-equivalent of a machine holiday. While the range is active the operator does not count as available, so any routing step that depends on that person's skill is scheduled around the gap: it slides to the next window where a qualified operator has free hours. A person's absence becomes a scheduling fact the engine acts on automatically.

This entry is part of the EDGEBIC by User Solutions glossary series; for the broader vocabulary of planning, see the manufacturing glossary. To enter one, follow how to record operator time off.

How Operator Time Off Works

An operator's availability is built from two layers. The base layer is the weekly roster: the recurring pattern of which shifts the person works, maintained once and left alone. The exception layer is time off: specific date ranges when the person is out, entered as needed on top of the roster.

When the engine assembles each operator's hours for a scheduling run, it starts from the roster and then subtracts any time off that overlaps the horizon. During a time-off range the operator contributes zero available hours, so no step that needs that person can be placed there. Keeping absences as exceptions, rather than editing the roster date by date, keeps the recurring pattern clean and puts every leave in one place.

The effect on the plan appears on the next reschedule. Steps that require the absent operator's skill and would have fallen inside the range move forward to the next feasible window. If several people hold the skill, the work simply flows to a colleague; if only one person qualifies, or the step is pinned to the absent operator, the step slides until they return.

A Concrete Example

Joe is out Monday through Wednesday. The planner records a single time-off range for Joe covering those three days, inclusive on both ends.

On the next reschedule, every step that needs Joe's skill and had been sitting in Monday through Wednesday is re-evaluated. Where another certified operator is free, the work moves to them and the plan barely shifts. Where Joe is the only qualified person, or the step carries a pin to Joe, the step slides to Thursday, the first day Joe is back with free hours. The planner did not touch a single job by hand; recording the absence once was enough to re-plan the affected work around it.

How EDGEBIC Uses It

Operator time off is a record you attach to an operator, and it feeds directly into the engine's labor availability:

• The engine feed subtracts time-off ranges from each operator's rostered hours, so during a leave the operator supplies no schedulable hours for any step.
• Reschedules route around it. Not-yet-started steps that need the absent person move to the next window where a qualified operator is free, with no manual reassignment.
• Actuals are protected. Work the operator already started or finished keeps its recorded dates; only remaining, unstarted work is re-planned around the absence.

Time off decides whether an operator is available at all; once they are, their schedule operator assignment records which steps the current plan has them working. Read the two together to follow a person from absence, through availability, to a dispatched crew, and use how to record operator time off to enter a leave.
