How do you calculate good units per shift from a dispatch plan?

Multiply units per cycle by cycles per shift for gross capacity, then multiply by availability and first-pass yield. With 50 units x 8 cycles x 88% x 95% you get 334.4 good units.

What is gross shift capacity?

It is units per dispatch cycle times cycles per shift before any losses, 50 x 8 = 400 units in the default. It is the ceiling you can never exceed in a shift.

Why split availability loss from yield loss?

They have different fixes: availability loss (48 units here) points to downtime and changeovers, while first-pass yield loss (17.6 units) points to scrap and rework. Knowing which dominates tells you where to act.

What is a good first-pass yield for dispatch planning?

It varies by process, but mature lines run 95%+ first-pass yield. The 95% default costs 17.6 units a shift even at high availability, so small yield gains compound across cycles.

Dispatch adherence vs OEE?

OEE multiplies availability, performance, and quality against a theoretical max; this calculator applies availability and yield to your actual dispatched plan to answer 'will this shift's work orders get done.'

How do I improve good units per shift?

Attack the larger loss first. In the default, availability loss of 48 units exceeds yield loss of 17.6, so reducing downtime would recover more output than chasing scrap.

MES, MOM & Shop-Floor Data Systems calculator

Digital Dispatch Adherence Calculator

Digital Dispatch Adherence translates your MES dispatch plan into the good units a shift can realistically deliver after availability and yield losses. Production schedulers and MES dispatchers use it to sanity-check whether the work orders they release are actually achievable, rather than nominal capacity that ignores downtime and scrap. The calculator separates the loss into an availability bucket and a first-pass-yield bucket, so you can see whether your gap to plan is an uptime problem or a quality problem. That distinction drives very different countermeasures on the floor.

What this calculator does

Estimate achievable good units per shift when dispatching work orders digitally, factoring in planned output, dispatch cycles, line availability, and first-pass yield.
Use when setting realistic shift output targets for digitally-dispatched work orders. Shows the difference between theoretical gross capacity and actual good units after availability and yield losses.
It computes good units per shift from units per dispatch cycle, cycles per shift, line availability, and first-pass yield, and breaks out the availability and yield losses.

Formula used

Gross shift capacity = units per cycle x dispatch cycles per shift
Good units per shift = gross capacity x (availability / 100) x (yield / 100)

Inputs explained

Planned good units per dispatch cycle:
Dispatch cycles released per shift:
Expected line availability:
Expected first-pass yield:

How to use the result

Use it when releasing or validating MES dispatch lists and you need a credible achievable-output number instead of theoretical capacity.
It treats availability and yield as single shift-level percentages, so mixed product runs or mid-shift changeovers with different rates need separate calculations.
