Capacity Planner
Available hours, utilization, and remaining capacity.
Additional Capacity
216units/wk
Total Available
200.0hrs/wk before downtime
Net Available
180.0hrs/wk after downtime
Current Production
503units/wk
Max at Full Capacity
720units/wk
126.0hrs
54.0hrs
Adding a shift could provide 200 additional hours per week.
Net Available Hours = (Hours × Shifts × Days × Machines) − Planned Downtime
Count only the machines that can run the work you are quoting, because Number of Machines multiplies straight into available hours. Planned Downtime is hours per week per machine, so enter maintenance and scheduled cleaning for one machine, not the whole cell. Hours Per Shift, Shifts Per Day and Days Per Week describe the schedule you actually staff, not the one on the capacity sign. Current Utilization is the share of net hours already committed to released work, measured against net hours rather than the calendar, or you will count downtime twice. Average Cycle Time is minutes per part at the machine, including load and unload but excluding setup.
Why is additional capacity higher than I expected?
Additional Capacity turns every remaining hour into parts at your Average Cycle Time, with no setups, no scrap and no material waits. It is an upper bound. If each run needs a changeover, fold the setup minutes into cycle time by dividing them across a typical lot, then read the figure again.
Is Planned Downtime per machine or for all machines?
Per machine, per week. The planner multiplies the figure by Number of Machines, so four hours across five machines means twenty hours removed from total available hours. Enter the downtime a single machine takes for maintenance, cleaning and scheduled inspection, and let the tool scale it.
What utilization should I plan capacity around?
This planner sets no target, because the right figure depends on how much variation your order book carries. A shop quoting short runs needs slack to absorb hot jobs and reworks; a line running one part can sit closer to full. Judge remaining hours against the work you expect next month.
What is the difference between capacity and utilization?
Capacity is the hours or units the machines could deliver; utilization is the share of those hours already spoken for. This page needs utilization as an input and returns capacity as an output, so the two are not interchangeable. A cell at seventy percent still has thirty percent of its net hours free.
How do I use this before quoting new work?
Compare Additional Capacity against the weekly volume the new order would add, then check the growth line: adding a shift gives you Number of Machines times Hours Per Shift times Days Per Week more hours. If the order needs more than the remaining hours, the choice is overtime, a shift, or a longer promise date.
Know Your True Capacity Before You Quote.
WorkCell tracks machine utilization in real time so you always know exactly how much capacity is available before committing to new work.
