Count drying and curing time without paying for it
A candle cures for two days. Nobody is paid for those two days, but the table is taken and the order cannot ship. Keelvy keeps three clocks apart so each answers its own question.
The three kinds of time
Section titled “The three kinds of time”On a step in the Works tab:
- Hours worked: how long the work itself takes, however that work is paid for. If you leave it empty because nobody has measured it, the cost is reported as incomplete rather than as free.
- Machine hours: how long the machine itself runs, not how long the person stands at it. Machine hours are costed at the resource’s hourly rate.
- Occupancy hours: elapsed hours the step ties up its resource or the line. Left empty, the step’s own hours count, or the whole cycle if it has none. Enter hours to override for drying, curing or waiting. Nobody is paid for them and they move the schedule, not the cost.
For a step with no person and no resource, such as drying, switch on Consumes no labor. The step then carries no position and no rate, and you enter Waits for, hours (once per order). These hours pass once for the whole order, however many pieces or batches it has. They are never multiplied. Heating is different: it draws power, so leave Consumes no labor off for it.
Per batch or per unit
Section titled “Per batch or per unit”Set Quantities are stated to Per batch or Per unit. Per batch stays the same however many you make, such as a setup or one kiln firing, which you add as its own step. Per unit is multiplied by the batch size. The step previews what it comes to for one batch.
Machines that run and tables that hold
Section titled “Machines that run and tables that hold”On the resource, It runs decides how time on it is treated:
- On for a machine: time on it is machine time, which is costed.
- Off for a shelf, a table or a room that only holds the work: it is occupied while the work takes and has no machine time.
If a resource holds several things at once, set Resource busy for, per load: how long this step keeps the resource busy for one load. An order is as many loads as it needs. A production order shows the loads, the rounds when identical units take loads in parallel, and the elapsed and machine hours. See Schedule production and see what is queuing.
On a real run
Section titled “On a real run”On a production order, the operations table has Machine hours and Occupancy hours for what actually happened. Machine hours reach the run’s cost the next time it is executed. A finished run keeps the cost it locked. Occupancy hours move the schedule rather than the cost.
