Ferrule Inventory Usage with hose assemblies to produce of 630 assemblies: a worked example

What does the result look like when hose assemblies to produce reaches 630 assemblies? The full calculation is worked below with real intermediate numbers. Use it when calculating the ferrule order quantity for a hose assembly production job to avoid line shortages.

The inputs for this scenario

  • Hose assemblies to produce: 630 assemblies (raised for this scenario; the documented default is 250)
  • Ferrules per assembly end: 1 ferrules / end (unchanged)
  • Fitting ends per assembly: 2 ends / assembly (unchanged)

Working through the calculation

  • Applying the documented formula (Theoretical ferrule count = assemblies x ferrules per end x fitting ends per assembly) to the inputs above produces each figure below.
  • At this operating point the engine returns 31,500 ferrules for required quantity, the number this scenario is built around.
  • At this operating point the engine returns 630 ferrules for theoretical ferrule count.
  • At this operating point the engine returns 30,870 ferrules for ferrule scrap or trial allowance.
  • At this operating point the engine returns 2 % for efficiency.

How this compares with the baseline

  • Against the tool's baseline example, where hose assemblies to produce sits at 250 assemblies and the headline result is 12,500 ferrules, this scenario comes in 152% above the baseline at 31,500 ferrules.
  • A figure at this level is achievable when hose assemblies to produce is genuinely sustained, not just peaked for a shift. The result is highly sensitive to the efficiency input; a low or misentered efficiency inflates the required quantity dramatically, as the worked example shows.

  • Required quantity: 31,500 ferrules (headline result)
  • Theoretical ferrule count: 630 ferrules
  • Ferrule scrap or trial allowance: 30,870 ferrules
