Compressor Test Capacity at 63% expected test stand uptime: a worked example

This worked example runs the compressor test capacity numbers for a tougher week than the baseline: 63% expected test stand uptime instead of the typical 88%. Estimate how many compressors a test station can actually release by combining slots per cycle, planned cycles, uptime, and first-pass yield.

The inputs for this scenario

  • Compressors completed per test cycle: 2 compressors / cycle (held at the documented default)
  • Available compressor test cycles: 36 cycles (held at the documented default)
  • Expected test stand uptime: 63 % (the input this scenario stresses; the baseline uses 88)
  • First-pass compressor release yield: 94 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross compressor test capacity = compressors completed per test cycle × available compressor test cycles.
  • Accepted compressor test capacity works out to 42.64 compressors at these inputs, and this is the headline figure for the scenario.
  • Gross compressor test capacity works out to 72 compressors at these inputs.
  • Compressor test stand downtime loss works out to 26.64 compressors at these inputs.
  • Compressor retest and rejection loss works out to 2.72 compressors at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected test stand uptime sits at 88% and the headline result is 59.56 compressors, this scenario comes in 28.41% below the baseline at 42.64 compressors.
  • Use it when sizing or load-balancing end-of-line compressor test stands against a target build rate, or when justifying a second test cell. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Accepted compressor test capacity: 42.64 compressors (headline result)
  • Gross compressor test capacity: 72 compressors
  • Compressor test stand downtime loss: 26.64 compressors
  • Compressor retest and rejection loss: 2.72 compressors
