Commercial Kitchen Equipment worked example
Service Parts Buffer with average service parts usage of 15 parts / day: a worked example in commercial kitchen equipment
What does the result look like when average service parts usage reaches 15 parts / day? The full calculation is worked below with real intermediate numbers. planning service parts stock for commercial kitchen equipment support
The inputs for this scenario
- Average service parts usage: 15 parts / day (raised for this scenario; the documented default is 6)
- Service parts replenishment lead time: 21 days (unchanged)
- Critical service parts safety stock: 40 parts (unchanged)
Working through the calculation
- Applying the documented formula (Service Parts Buffer lead-time demand = average service parts usage × service parts replenishment lead time) to the inputs above produces each figure below.
- At this operating point the engine returns 0.02 days for protected days of supply, the number this scenario is built around.
- At this operating point the engine returns 0.71 days for unprotected days.
- At this operating point the engine returns 15 pieces for inventory.
- At this operating point the engine returns 21 pieces / day for daily usage.
How this compares with the baseline
- Against the tool's baseline example, where average service parts usage sits at 6 parts / day and the headline result is 0.01 days, this scenario comes in 150% above the baseline at 0.02 days.
- A figure at this level is achievable when average service parts usage is genuinely sustained, not just peaked for a shift. It assumes steady daily usage; a seasonal rush or a single large account's equipment failure can spike demand well above the average the buffer is sized for.
