Water, Wastewater & Pump Systems Manufacturing worked example

Pump Assembly Cycle Time at 12% setup, staging, and delay allowance: a worked example

Push setup, staging, and delay allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when pump assembly cycle time in water, wastewater and pump systems manufacturing is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Pumps to assemble this run: 120 units (unchanged)
  • Assembly line throughput rate: 12 units / min (unchanged)
  • Setup, staging, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base pump assembly cycle time = pump assembly cycle time workload รท pump assembly cycle time completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required pump assembly cycle time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base pump assembly cycle time.
  • At this operating point the engine returns 12 % for pump assembly cycle time allowance applied.
  • At this operating point the engine returns 12 pieces / min for pump assembly cycle time completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, staging, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It computes the required assembly hours for a pump build by dividing quantity by line rate and inflating that base time by a setup and delay allowance. 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

  • Required pump assembly cycle time: 11.2 hr (headline result)
  • Base pump assembly cycle time: 10 hr
  • Pump assembly cycle time allowance applied: 12 %
  • Pump assembly cycle time completion rate: 12 pieces / min
