Model Changeover Cost Calculator at 110% changeover cost scope included: a worked example
Push changeover cost scope included up to 110% and the picture changes. This example computes every intermediate figure at that operating point. a production manager needs to quantify the cost of model changeovers in high-mix appliance production
The inputs for this scenario
- Model changeover hours: 38 hr (unchanged)
- Loaded line cost during changeover: 420 $ / hr (unchanged)
- Changeover cost scope included: 110 % (raised for this scenario; the documented default is 100)
- Fixed setup, tooling, or approval cost: 2,800 $ (unchanged)
Working through the calculation
- Applying the documented formula (Variable changeover time cost = model changeover hours × loaded line cost during changeover × changeover cost scope included) to the inputs above produces each figure below.
- At this operating point the engine returns 20,356 $ for total model changeover cost, the number this scenario is built around.
- At this operating point the engine returns 536 $ / hr for loaded line cost during changeover.
- At this operating point the engine returns 17,556 $ for variable changeover time cost.
- At this operating point the engine returns 2,800 $ for fixed setup, tooling, or approval cost.
How this compares with the baseline
- Against the tool's baseline example, where changeover cost scope included sits at 100% and the headline result is 18,760 $, this scenario comes in 8.51% above the baseline at 20,356 $.
- It computes the total dollar cost of a model changeover from downtime hours, loaded line cost, an attributable scope percentage, and fixed setup costs. 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.
Results at a glance
- Total model changeover cost: 20,356 $ (headline result)
- Loaded line cost during changeover: 536 $ / hr
- Variable changeover time cost: 17,556 $
- Fixed setup, tooling, or approval cost: 2,800 $
