Job Shop Quote at 94% practical shop availability: a worked example
Push practical shop availability up to 94% and the picture changes. This example computes every intermediate figure at that operating point. checking whether a requested lot size fits the open shop calendar before sending a quote
The inputs for this scenario
- good parts per production slot: 18 parts / slot (unchanged)
- available production slots in the quote window: 24 slots (unchanged)
- practical shop availability: 94 % (raised for this scenario; the documented default is 82)
- quoted first-pass yield: 96 % (unchanged)
Working through the calculation
- Applying the documented formula (Gross quoted part capacity = good parts per production slot × available production slots in the quote window) to the inputs above produces each figure below.
- At this operating point the engine returns 390 parts for quoteable good parts capacity, the number this scenario is built around.
- At this operating point the engine returns 432 parts for gross quoted part capacity.
- At this operating point the engine returns 25.92 parts for parts lost to unavailable shop time.
- At this operating point the engine returns 16.24 parts for parts lost to scrap and rework.
How this compares with the baseline
- Against the tool's baseline example, where practical shop availability sits at 82% and the headline result is 340 parts, this scenario comes in 14.63% above the baseline at 390 parts.
- It computes quoteable good-parts capacity by derating gross slot capacity for practical shop availability and quoted first-pass yield. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
