Questions about this calculator

Why not use maximum machine speed?

Planning should use sustained good output for the product and format, including normal minor stops.

Does efficiency include rejects?

Use a good-output rate or make sure the efficiency assumption includes quality loss consistently.

How should cleaning be handled?

Add it as fixed planned time if it occurs once per batch, or include it in the schedule separately.

Can several machines be compared?

Yes, provided the same batch boundary, quality requirement and downtime assumptions are used.
