Wire Drawing & Rod Processing worked example
Line Throughput at 99% line operating efficiency: a worked example in wire drawing & rod processing
What does the result look like when line operating efficiency reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when line throughput in wire drawing and rod processing is being committed and you need a throughput number you can defend.
The inputs for this scenario
- Coils completed: 1,200 units (unchanged)
- Drawing line run time: 8 hr (unchanged)
- Line operating efficiency: 99 % (raised for this scenario; the documented default is 90)
Working through the calculation
- Applying the documented formula (Raw line throughput = completed output รท runtime) to the inputs above produces each figure below.
- At this operating point the engine returns 149 units / hr for effective throughput, the number this scenario is built around.
- At this operating point the engine returns 150 units / hr for raw throughput.
- At this operating point the engine returns 99 % for efficiency.
- At this operating point the engine returns 8 hr for runtime.
How this compares with the baseline
- Against the tool's baseline example, where line operating efficiency sits at 90% and the headline result is 135 units / hr, this scenario comes in 10% above the baseline at 149 units / hr.
- A figure at this level is achievable when line operating efficiency is genuinely sustained, not just peaked for a shift. It treats efficiency as a single multiplier and assumes steady-state running; it will not distinguish speed loss from micro-stops or quality slowdowns, so it is a planning rate, not a root-cause tool.
