Is this the same as parallel station capacity?

The capacity arithmetic is the same, with different labels. This page checks one rate against required output; the parallel capacity page adds the one-station-down case that redundancy planning needs.

Which yield belongs in this page?

First-pass yield for the group, measured at the end of the stations, not rolled throughput yield of the whole line. Count reworked units as not first-pass good even when they ship later.

Why multiply station count by cycles instead of adding timed cycles?

Because equivalent stations run at the same time on different units. Adding the rate of one station once per station is the same arithmetic, but multiplying keeps the single-station rate visible for the loss rows.

Can uptime above 100 percent happen here?

No. Uptime is a share of available time and caps at 100. If your counter shows more cycles than available time allows, the cycle count or the rating is wrong.

Multi-Station Throughput Calculator

Compute the hourly output of several equivalent stations from their cycle count, then derate it for downtime and rejects. The gap against required output tells you whether the station group can feed the next process.

What this calculator does

Good units per hour across parallel stations after uptime and first-pass yield, checked against required output.

Formula used

Gross station throughput = producing stations × cycles per station-hour
Good throughput = gross throughput × station group uptime % ÷ 100 × first-pass yield % ÷ 100
Throughput lost to downtime = gross throughput − gross throughput × uptime % ÷ 100
Throughput lost to rejects = gross throughput × uptime % ÷ 100 − good throughput
Throughput gap = required output − good throughput

Inputs explained

Producing Stations: Stations, lanes or heads making equivalent units in parallel.
Cycles per Station-Hour: Standard or counted cycles one station completes per hour.
Station Group Uptime: Run time ÷ available time for the group, from downtime logs.
First-Pass Yield Through Station Group: Good units ÷ units started, reworked units counted as not good.
Required Output: Good units per hour the next process or schedule needs.

How to use the result

Best suited to sizing a parallel machining cell, checking a station group before a rate rise, choosing between uptime and yield projects.
An average rate over the window; a single slow station or a mix change will shift the result. Downtime and rejects are separate losses. A station that jams and scraps the jammed unit is counted in both.

Current U.S. benchmarks

The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
