Control Board Capacity Gap Calculator at 99% constrained process uptime: a worked example

Push constrained process uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a production planner needs to compare available control board capacity with appliance build demand

The inputs for this scenario

  • Boards completed per constrained cycle: 4 boards/cycle (unchanged)
  • Available constrained-process cycles: 900 cycles/shift (unchanged)
  • Constrained process uptime: 99 % (raised for this scenario; the documented default is 86)
  • Combined good-board yield: 95 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross scheduled board capacity = boards completed per constrained cycle × available constrained-process cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,386 boards/shift for usable control board capacity, the number this scenario is built around.
  • At this operating point the engine returns 3,600 boards/shift for gross scheduled board capacity.
  • At this operating point the engine returns 36 boards/shift for boards lost to process downtime.
  • At this operating point the engine returns 178 boards/shift for boards lost to combined yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where constrained process uptime sits at 86% and the headline result is 2,941 boards/shift, this scenario comes in 15.12% above the baseline at 3,386 boards/shift.
  • It computes usable good-board capacity per shift at the constrained process after applying uptime and combined yield, and shows the boards lost to each. 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

  • Usable control board capacity: 3,386 boards/shift (headline result)
