Hydraulic System Test Capacity at 99% expected test-cell uptime: a worked example

Push expected test-cell uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when hydraulic system test capacity in port, crane and terminal equipment is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Hydraulic assemblies tested per cycle: 4 units / cycle (unchanged)
  • Available test cycles in the window: 480 cycles (unchanged)
  • Expected test-cell uptime: 99 % (raised for this scenario; the documented default is 90)
  • Expected first-pass test yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross hydraulic system test capacity = hydraulic system test capacity output per cycle × available hydraulic system test capacity cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good hydraulic system test capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross hydraulic system test capacity.
  • At this operating point the engine returns 19.2 units for hydraulic system test capacity downtime loss.
  • At this operating point the engine returns 57.02 units for hydraulic system test capacity yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected test-cell uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • It multiplies units per cycle by available cycles for gross capacity, then multiplies by uptime and first-pass yield to give good tested output, with the losses broken out separately. 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

  • Good hydraulic system test capacity: 1,844 units (headline result)
  • Gross hydraulic system test capacity: 1,920 units
  • Hydraulic system test capacity downtime loss: 19.2 units
  • Hydraulic system test capacity yield loss: 57.02 units
