Analyze operator capacity

Some operators are not assigned 100% of the time to a line during every cycle. Part-time operators often have other tasks to complete in parallel with work on the line.

Example

For example, an operator may only be available to work 50% of the time at the balanced line. The rest of the time, the operator may work on a mirrored line in the next station.

When you perform balancing, account for any part-time operators assigned to the line, so the line does not exceed defined takt time.

Note

An operator with a capacity of less than 100% may not be shared, meaning that the operator is not available to do work in other stations. If an operator is already shared, the person cannot have a capacity less than 100%.

Process Planning for BTO/BTS/CTO treats operators as process resources (PRs) during calculations. Process Planning for BTO/BTS/CTO uses this formula to calculate available takt time for a part-time PR:

Line takt time * capacity of PR.

Example

Takt = 60

Operator is assigned to station 50% of their time

Calculated takt time for the part-time operator is 30

Allocated work = 25

Available time = 5
